Hi
The iOS/Android ports are finally ready for beta-testing. This happens one month after the expected date, sorry for the delay (everyone is very busy -- more than usual). Until Jonathan pushes the code to the public repository, here is what you need to know if you want to play with them.
Where?
The ports will be available in the ios_and_android branch of the repository. This way it won't bother people who are not interested, and the amount of testers (and reports) is kept under control.
How to compile the iOS port?
To compile the iOS port, you must use the Xcode generator of CMake, and define the "IOS" boolean variable (set to TRUE) before configuring for the first time. The generated projects can then be compiled for x86 (simulator) or armv6/v7 (device) by selecting the target in Xcode; no need to generate multiple builds for that. SFML is built as static libraries on iOS (this is the only option for this OS).
To use SFML in your iOS app project, do as usual: add the include path to your project settings, and drag'n'drop the libraries into your project. Since SFML is linked statically, you'll have to link all its non-default dependencies as well (extlibs/libs-ios).
Note that you'll need a registered Apple developer account in order to copy and run your app on a device; otherwise the simulator will be your only choice.
How to compile the Android port?
How to compile the OpenGL ES port for Linux?
Things to know for Android
Jonathan will explain that as soon as he is available ;)
New API
Only a few things have been added to the public API:
- The sf::Keyboard::setVirtualKeyboardVisible function
- The Touch API:
- A sf::Touch class (similar to sf::Mouse)
- sf::TouchBegan / sf::TouchMoved / sf::TouchEnded events (similar to mouse events)
General things to know
The sensors (accelerometer, gyroscope, compass, ...) are currently using the Joystick API (see the sources for more detail about the mapping). We'll soon add a sf::Sensor API that better matches the requirements.
The foreground / background events are mapped to the GainedFocus and LostFocus events.
Orientation changes are mapped to the Resize event.
sf::Shader is not available, because the implementation is based on OpenGL ES 1. Shaders are only available in OpenGL ES 2, which would require a major rewriting of the graphics part. So that won't be done in a near future.
Things to know for iOS
On iOS, the working directory is automatically set to the resources directory.
There's no audio module on iOS, I'm still waiting for libsndfile to add a license exception for iOS so that I can use it statically without breaking the terms of the license. The author said it was one of its priorities, but it was months ago and I've got no news...
The implementation should be compatible with iOS 4.0 and more.
The size of the window is ignored, the screen size is always used.
Examples are not available. It seems that CMake is not ready for that, it still requires too many hacks, and even with them, it was still pretty bad.
The ugly hack: you need to include <SFML/Main.hpp> in the file where your main function is defined. This is because SFML has to hijack it, and rename your own main to call it later.
There's no specific support for high-resolution (retina) screens, they currently produce the same output as low-res screens (this will be done later).
Important
Until everything is merged into master, please use the forum for your feedback. You can post here or open new threads. There are still many things to do, I don't want to pollute the task tracker ;)

Note
For those who aren’t familiar with git, once the SFML repo freshly cloned, type: git checkout –b ios_and_android origin/ios_and_android to get the right branch.
How to compile the Android port?
To compile the Android port, you must use CMake with the toolchain configuration script located at cmake/toolchains/android.toolchain.cmake. To do that, define the CMAKE_TOOLCHAIN_FILE variable when invoking CMake and make it point to the android.toolchain.cmake script. You’ll also need to define an environments variable ANDROID_NDK telling where the NDK directory is. There are a few options available to customize the build process:
ANDROID_ABI : armeabi, armeabi-v7a, x86, mips
ANDROID_NATIVE_API_LEVEL: 9, 14, 18, etc.
ANDROID_USE_STLPORT: Make sure this one is set at TRUE because I’m not sure if it’s set automatically. Usage of the STL port is MANDATORY. If you don’t use it, no error will be reported and your application will just.. crash :)
Once compiled, type "make install" to install everything in your NDK directory.
Getting familiar with the compilation process of native Android application isn’t an easy task so, don’t give up and read carefully the NDK documentation. Maybe you should start with compiling an official example such as NativeActivty located in your NDK. You’ll need to get through this because you won’t be able to reuse this CMake toolchain script to compile your own application (unless your application is a library :D).
There’s an example available in the SFML source files directory. I advise you to “create a project from existing source” from the Android IDE (Eclipse). Once the example imported and set up, you can’t simply press the “Run” button, you’ll need to compile the example project first. To do that, open a console, head to the example directory and invoke the ndk-build script located in your NDK: your command might look like this: $ANDROID_NDK/ndk-build
Things to know for Android
On Android, the working directory is automatically set to the resources directory (assets/).
sf::SoundRecorder won’t record any sounds.
Since recently I no longer get the orchestral.ogg song to play with sf::Music ... but canary.wav does work.
The implementation is compatible with Android 9 or later.
You may have to install some 32bits libs on Linux. I can’t tell which exactly but on Fedora 64bits, type the following: sudo yum install glibc.i686 glibc-devel.i686 libstdc++.i686 zlib-devel.i686 ncurses-devel.i686 libX11-devel.i686 libXrender.i686 libXrandr.i686. If someone could give the list for Debian based distribution, it would great!
How to compile the OpenGL ES port for Linux?
Unfortunately, this isn’t available yet because I need to refactor the EGL code to avoid duplication, as well as time to test the new CMake scripts on a Raspberry Pi. I’ll implement this really soon.
Important
I really am busy right now and I won't be able to provide much support until 8th of December.

First: Thanks for your work. :)
I tried to build SFML, however I get errors inside the NDK. Since I'm very unexperienced with it, I ask if something like this is known anyhow:

It seems that NDK version r9b has been released in the meantime. I use version r9 so try to downgrade, even if it's unlikely to be because of this new version.
Try:
export ANDROID_NDK=/path/to/ndk
cd SFML/
mkdir build && cd build
cmake -CMAKE_TOOLCHAIN_FILE=../cmake/toolchains/android.toolchain.cmake -DANDROID_USE_STLPORT=1 ..
make -j8
-
Thanks, will try that.
-j8? I only have 4 gigs of RAM, do you want to freeze my system? :P
Edit: I was able to build SFML with NDK version 9.

Hey, so I followed the Android instructions, nearly the same as for eSFML, so I don't think I did something wrong.
I created a project from the android example, added native support, then compiled it, everything works fine until my phone tries to launch the application.
Here are the logcat logs, I tried it on two phones: Galaxy S (android 2.3.4), and HTC ONE X (tegra 3) (Android 4.2.2).

On a emulator it just get stuck during the launching phase with no error.
P.S. I compile it again to exclude a mistake in the setup

added native support
???
You don't need to right-click on the project then "Add native support...". I'll explain how it works internally later.
P.S. I compile it again to exclude a mistake in the setup
Does that mean it works now? :D
-
No its still not working yet. The ndk examples runs fine, so I guess its not an error in my setup (at least the sdk/ndk part)
When I do not add native support I get an error the phone cant find the shared library...
Btw i test it on windows, tomorrow I will try it on ubuntu...
AlexAUT
-
For now, you're forced to have your application library named "sfml-example" (libsfml-example.so) because the SFML Activity (libsfml-activity.so) that comes along when you compile SFML doesn't take the customized application name into account.
In the meantime, you can either modify Main/SFMLActivity.cpp line 145 or fix it :D
Good luck!
-
Ok i am currently not at home, out clubbing ;)
But thanks for your help I will try it later!
Edit: I downgraded my NDK from 9b to 9 and set everything up again and now it works(without setting the native lib support)... Awesome work!

So... since this should also be compilable on a normal system, I went ahead and tried it out.
Didn't compile because <SFML/System/Err.hpp> was missing from GLExtensions.cpp for err() and std::endl.
Fixed that, then went ahead to check out all the warnings I got with my crazy warning settings enabled :).
-Wall -Wextra -Wconversion -Wshadow -Wunreachable-code -Wredundant-decls -Wcast-align -Wfloat-equal -Wno-long-long -Wformat=2 -pedantic
First and most importantly, is it necessary to redefine the OpenGL extension function names even if they exist already? From what I understand, the suffix added to the function names just denote which vendor/working group is taking care of the extension before it gets reviewed by the ARB and then put into the core specification. So overwriting say glGenFramebuffers with glGenFramebuffersEXT doesn't seem right to me if glGenFramebuffers already exists. Wouldn't it be nicer to have some form of #if !defined() guards around each function?
I also went ahead and cleaned out many conversion warnings that popped up. Most conversions shouldn't have made a change to behaviour, but some others do in fact change behaviour in slight ways that were probably not noticed by anyone yet ;). Free "bug" fixes.
Here is the diff. When I push my branch to GitHub it completely messes up the line endings, because well... SFML line endings are a mess already :P. Laurent or someone should just tell git to normalize them one day, see: https://help.github.com/articles/dealing-with-line-endings
Patch here: patch.diff (http://pastebin.com/UWTXkdTT)

As I read up on ARB_framebuffer_object and EXT_framebuffer_object recently, I can say they are subtly incompatible and should not be mixed up, because they have different internal code. The EXT version gets shared beweens contexts, while the ARB (or GL3.0) version does not and contains other extensions. One should not call functions of one of them, then functions of the other.
And its not the only extension where older extensions were modified, not just promoted.
-
Didn't compile because <SFML/System/Err.hpp> was missing from GLExtensions.cpp for err() and std::endl.
Ah. Strange thing that it compiled for me (I can understand how <iostream> may be included indirectly depending on the compiler/OS, but <System/Err.hpp>?).

Yes, it's probably a bad thing to reuse the core name of the function. But I don't think testing it with preprocessor directives would solve the problem: it will be a macro only if defined by GLEW; if it is defined in the GL header, it will be a regular function.
I also went ahead and cleaned out many conversion warnings that popped up. Most conversions shouldn't have made a change to behaviour, but some others do in fact change behaviour in slight ways that were probably not noticed by anyone yet
I don't understand why so many casts would be needed. As far as I know, "anything op float" yields a float, so there's no need to cast both operands every time.
SFML line endings are a mess already :P. Laurent or someone should just tell git to normalize them one day, see: https://help.github.com/articles/dealing-with-line-endings
Yep. I thought I had configured git correctly... obviously not.
-
Yes, it's probably a bad thing to reuse the core name of the function. But I don't think testing it with preprocessor directives would solve the problem: it will be a macro only if defined by GLEW; if it is defined in the GL header, it will be a regular function.
But the problem is, it will never be defined in the GL header, at least on Windows, unless Microsoft decides that Windows should support a more recent version of OpenGL than what... 1.1? That would break all their precious customers' systems who don't have cards that can support anything more recent, which is also why DirectX has a hardware emulation layer. If OpenGL had a software rasterizer fallback that took care of newer features it wouldn't be a problem to do so, but it isn't part of the standard and Microsoft hasn't shown any interest in it either.
This is why GLEW goes ahead and defines even core functions. The goal is that every extension that is proposed goes through a sort of standardization process.
First it is probably only supported by a single vendor AMD/Nvidia, then it has the NV or ATI/AMD suffix.
Once the vendor can convince other vendors that what they are doing is good, it gets the EXT suffix.
When it is submitted to ARB for becoming part of the core API, it gets the ARB suffix.
Finally when it gets into the core specification it loses all suffixes.
The function will stay in the GLEW header, probably forever, but over time it will change its name, and maybe even its functionality a bit.
The only reason why the redefinitions that are in GLExtensions.hpp work now, is because the assumption that "if the card supports the core function it supports the EXT variant as well" holds. As wintertime already said, this can be problematic because they are not required to have the same behaviour, and it is up to the card manufacturers to drop support for legacy APIs if they have had core support for a long time. It might just be that at some point glGenFramebuffers will be available from GLEW, but glGenFramebuffersEXT not, and with those redefinitions you are overwriting a working name with a non-working one. This will break things because the redefinition takes place after you include GLEW the first time and if the compiler can't find the definition of glGenFramebuffersEXT after the preprocessor replaces glGenFramebuffers with it, or even worse tries to call glGenFramebuffersEXT although it is not set up, bad things will happen.
I think if you need a common entry point for those different GL functions you should create your own name block for it, something like SFGenFramebuffers and use the GLEW extension probing macros to decide which to assign to it, favouring core functions of course. This is how many other libraries alias lower level functionality in such situations.
I don't understand why so many casts would be needed. As far as I know, "anything op float" yields a float, so there's no need to cast both operands every time.
In the case of a binary operation, yes that is true, but it is also a matter of signalling the programmer's intention, and technically, if you cast one operand on the right-hand-side just to get a floating point operation, you are losing precision over casting the result after the integer operation instead.
When there are more operands involved it sometimes isn't always obvious in what order the implicit casts will take place. The goal is to cast as late as possible to take advantage of lossless integer operations but early enough if you know an integer operation will lose precision because it can lead to a fractional value.
I've just made it a habit to explicitly specify casts for everything so I know exactly what happens. Leaving things up to the compiler to decide works most of the time, but when higher level semantic knowledge gets involved, the compiler doesn't really have many possibilities to be smart about how it generates code, especially in a case where the standard instructs it to do something we didn't expect.
-
But the problem is, it will never be defined in the GL header, at least on Windows
But things are not limited to Windows, as you perfectly know ;)
Regarding casts: if nothing's broken then I prefer leaving the code as it is now. I'm not a big fan of those long lines of code where 80% of space is taken by occurences of the "static_cast" keyword. Of course your approach is safer, but I think it's a point where I can make a compromise ;)
-
But things are not limited to Windows, as you perfectly know ;)
But Windows is supported, and should not break even in such situations, as you perfectly know ;)

I just said that your solution based on the preprocessor might not work on Linux and OS X. I never said that I didn't want to solve this issue; sorry if it was not clear.

Why wouldn't it work? The names are part of the OpenGL extensions that are quasi-standard and the preprocessor should work the same on all platforms unless you have a really broken compiler ;). I haven't seen any special versions of said functions that only exist on a certain platform... There is only one GLEW header that you use on all platforms and it defines the same functions that are available.

Actually, now that I checked, when you include glew.h it basically "pretends to be gl.h" by defining __gl_h_ itself so that if you include gl.h after glew.h it does nothing. If you do the opposite and include gl.h before glew.h an #error will be triggered so that isn't even possible. So as long as you include glew.h you will have access to all the functions and definitions no matter what gl.h version you have. There is no way to prioritize one or the other. You can't use both at the same time anyway, either you use glew.h or gl.h but not both.

If you include an OpenGL 2+ header, it will declare these functions directly, not as macros. The preprocessor won't see them, and your test will fail although the functions are already defined.

Interesting. So I guess this closes the discussion ;)
I'll rename my own identifiers so that no confusion / conflict is possible anymore.

So I have tried to port Kroniax for Android, and found a few bugs in SFML ::)
1.) The SFML app crashes when you try to change the orientation, e.g. turn the phone to landscape mode. Error code in logcat: "validate_display:294 error 3008 (EGL_BAD_DISPLAY)"
Current fix: Force one orientation, e.g. "android:screenOrientation="landscape" "
2.)sf::Sprite doesn't support transparent images, the transparent pixels are black or white instead of transparent. Also the non transparent colors aren't drawn correctly. See attachments(the sprite in the app, and the raw image)
3.)I think Jonathan already mentioned it that sf::Music can't play *.ogg files. the openFromFile always return false.
4.)I dont know if its just because of the license of GNUSTL(good c++11 support) but it would be nice if SFML wouldn't force us to use the STLPORT(little c++11 support). (not really a bug)
EDIT:
5.)Fonts/Text seems not to work too -> (http://i.imgur.com/fx9lCMg.png)
But anyway great work, thanks!

Nobody for iOS? :'(
I'll probably try later. :) I've been waiting on this for a while.
I only have access to the simulator though.

For those who don't know: you can also run your compiled apps on a jailbroken device.

I'm trying to build the android port but it is not working. Cmake says that the CMAKE_TOOLCHAIN_FILE isn't being used by the project

There
At first it was having issues finding the OS X 10.9 SDK. I don't know if it is my computer, but I found it in "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk". I think it has something to do with XCode coming through the app store now, but that's just a random guess.
Then I had this:
CMake Error at CMakeLists.txt:231 (install):
install FILES given no DESTINATION!
CMake Error at CMakeLists.txt:232 (install):
install FILES given no DESTINATION!
Configuring incomplete, errors occurred!
See also "/Users/Chase/Desktop/Programming/build/SFML-ios/CMakeFiles/CMakeOutput.log".
See also "/Users/Chase/Desktop/Programming/build/SFML-ios/CMakeFiles/CMakeError.log".
After looking at CMakeLists.txt I tried defining INSTALL_MISC_DIR manually, which worked.
Also this. (https://github.com/SFML/SFML/commit/24aa04fd4cebb9b44cbac41154fdbb497b97e7ca#commitcomment-4748774)
Other than that it built successfully, but I'll have to actually try it another time later today.
-

Hmm I've never had problems with that. My Xcode was installed with the app store too, and as far as I remember the SDK was found at the same location -- automatically of course.
However I'm not up-to-date: Xcode 4.6 (I think ;D) and OS X 10.7.

However I'm not up-to-date: Xcode 4.6 (I think ;D) and OS X 10.7.
I'm using Xcode 5.0.1 and OS X 10.9. I really have no clue what it is then. I don't have much experience with anything beyond a couple of experiments here and there.
So I tried a simple test app, and when it linked it gave some errors until I added the non-default libraries from here (https://github.com/SFML/SFML/blob/ios_and_android/src/SFML/Window/CMakeLists.txt#L184). It took me a while to figure that out and how to do it (properly), but I suppose it doesn't help that I haven't used XCode much since sometime in OS X 10.5/6.
Now that it is running all I get is a black screen for this:
#include <SFML/Main.hpp>
#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>
int main( int argc, const char* argv[] )
{
sf::RenderWindow window( sf::VideoMode( 0, 0 ), "Testing SFML" );
//window.setFramerateLimit( 50 );
sf::RectangleShape shape;
shape.setSize( sf::Vector2f( 100, 100 ) );
shape.setPosition( 50, 50 );
shape.setFillColor( sf::Color::Blue );
bool isRunning = true;
while ( isRunning )
{
sf::Event event;
while ( window.pollEvent( event ) )
{
//
}
window.clear( sf::Color::White );
window.draw( shape );
window.display();
}
return 0;
}
The only iOS SDK I have available is 7.0 (simulator 7.0.3), so I wasn't able to test on anything else.

Oops, this is an important thing that I forgot to explain ;D Since SFML is linked statically, you have to link its dependencies yourself in your application.
Now that it is running all I get is a black screen for this
What if you use a valid size for the window? It is ignored by the window, but I think the default view still uses it.
-

Oh, that makes since. I don't link statically very often, and when I have I did it before that was needed on Windows. :P
What if you use a valid size for the window? It is ignored by the window, but I think the default view still uses it.
I was originally using (640, 480), but was trying to change it to see if something different would happen.
Shouldn't the screen at least be white though, since I'm clearing with sf::Color::White? I can't remember if that works with OpenGL ES, it has been a while since my attempt at it.
-

This may be the splash screen that automatically appears until the app is ready to run. Try to provide a custom one.

It shows up for a second and fades then fades to black.
-
You can also try iOS 6 instead of 7: in your project properties, select iOS 6 for "deployment target", and in the simulator, select iOS 6 too.
-
That was obnoxious. (https://github.com/SFML/SFML/pull/503)
Anyways, Starbound is out. I'm going to be fairly distracted now. :P
(EDIT: I guess I should make it a little bit more clear, it does work now.)

Great! :D

Example app is crashing (SIGSEGV) for me using SDK 17 and 19 with NDK r9 (Asus Transformer Prime, Android 4.1.1):
I/DEBUG (27754): backtrace:
I/DEBUG (27754): #00 pc 0000fc2a /system/lib/libutils.so (android::String8::appendPath(char const*)+5)

The previous ESFML build worked without problems. The crash happens for both resources, the image as well as the audio file.
Edit:
My bad, obviously forgot to set ANDROID_USESTLPORT and it's working now. :)
-
Hi there,
Thanks for the port ! I will try both android and iOS very soon (or when I have time...) . Simulator, iPhone and iPad :)
Good luck with that.
-
Is the stable version available soon? I would like to use SFML for my Android game project.

The more you help us stabilize it, the sooner it will be ready. ;)
Soon Jonathan will have time to go over the reports and we'll see where we can go from there.
-
Playing with it some more, hopefully with less silly mistakes. It seems there might be an issue with sf::Event::LostFocus on iOS. Using this:
#include <iostream>
#include <SFML/Main.hpp>
#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>
int main( int argc, char* argv[] )
{
sf::RenderWindow window( sf::VideoMode( 1, 1 ), "Testing SFML" );
window.setFramerateLimit( 50 );
sf::RectangleShape shape;
shape.setSize( sf::Vector2f( 100, 100 ) );
shape.setPosition( 50, 50 );
shape.setFillColor( sf::Color::Blue );
std::cout << "start" << std::endl;
bool isRunning = true;
while ( isRunning )
{
sf::Event event;
while ( window.pollEvent( event ) )
{
if ( event.type == sf::Event::LostFocus )
{
isRunning = false;
}
}
shape.move( 0, 2 );
std::cout << "loop " << shape.getPosition().y << std::endl;
window.clear( sf::Color::White );
window.draw( shape );
window.display();
}
std::cout << "term" << std::endl;
return 0;
}
The program runs fine. When leaving the app, "loop <...>" stops appearing, but "term" does not appear. When reopening it, "term" appears and the screen stays black.
If I leave and reopen again, instead of rerunning the app, it crashes with EXC_BAD_ACCESS here (https://github.com/SFML/SFML/blob/ios_and_android/src/SFML/Window/iOS/SFAppDelegate.mm#L170).
Also, it when loading a font I get 'Failed to load font "Arial.ttf" (failed to create the font face)'. I'm not sure if I put it on the wrong place though, I'll have to look more into it later.
Sprites/textures and touch events worked very well though. :) My testing has been pretty simple so far.
-
Font loading is broken at the moment, same happens for Android.
-
Thanks for waiting! I'm now available to dig into these issues :D
So, what do we have here:
1) Crash when orientation changes (unless you set android:screenOrientation at landscape)
2) Alpha color issue
3) Figure out why some audio format cannot be played.
4) Drop stlport in favor of gnustl since it has poor C++11 support
5) sf::Text displays white rectangles
6) Add support for NDKr9b
Bug number 2 and 5 are fixed but I haven't pushed anything yet because I need confirmation from the iOS port.
I'm trying to build the android port but it is not working. Cmake says that the CMAKE_TOOLCHAIN_FILE isn't being used by the project
This message shows up when I rerun CMake so don't worry, it's being used by the project.
Font loading is broken at the moment, same happens for Android.
What happens exactly? Does it fail to load any font file ? Or is it the same as bug number 5 ?

I just finished porting my game so I guess it's stable enough to start developing a game :D
Thanks everyone for your feedbacks and reports! :)

iOS apps crash if you terminate them. That's a know bug.
Font loading is broken at the moment
No it's not, I've never had any problem with fonts on iOS. It's most likely a resource directory issue (try to load a texture for example).

Unicolored quads, exactly. Size, offsets, etc. are perfectly fine, just missing transparency and/or texture coordinates (didn't check so far).

Well, on Android. :) See above.
-
It's great to see these ports coming along! I've compiled the libs for ios, but haven't got around to testing a basic application yet. Hopefully I'll get a chance soon.
-
Hi,
I'm on the iOS port too. :D
I've tried to build it whitout any succes.
First error that pops to me : it can't find <GL/glew.h> to fix it I had to modified XCode projet and add a user search Path to the extlibs/header you've provided.
Then it couldn't find <OpenGL/glu.h> and I don't know why.... I will look further more later.
I've recently moved to Maverick via update and install the last XCode (5.something) through AppStore. So it's might be to link to all of this. Maybe a clean install will help.... :(
Still, I'm eager to try this ^^
Thanks for the work you've done.
-
Bug number 2 and 5 are fixed but I haven't pushed anything yet because I need confirmation from the iOS port.
Can't wait for the fixes to be public repo because currently it is impossible to use the Android port (sf::Text and sf::Sprite issue).

I'll send a fix tonight with the EglContext code improvaed and refactored to be used on Linux and other EGL based OSes.
-
I ended up with changes in some CMake scripts and I still need to test whether SFML compiles okay on Windows before pushing anything. It should be ready tonight!
-
Push it and drop me a PM, it's an experimental/unstable branch after all. :)
-
Unfortunately I don't have access to the code right now so I can't push it :( By the way, rewriting commits leads to confusion, that's why I prefer to wait in general :p
If you're looking for the code that fixes the font and transparency issue, I haven't fixed it properly yet actually... (not sure if it'd still work on the iOS side). Anyways, here's a quick temporary fix: replace "GL_OES_blend_func_separate" with "false" in Egl src/SFML/Graphics/GlExtensions.hpp lin 37.
You may have to set EGL_BIND_TO_TEXTURE_RGBA at True in src/SFML/Window/Android/EglContext.cpp (be careful there are three occurrences).
I'll sort this thing out tonight before pushing EglContext refactored :)
-
Can wait, just thought you're just waiting for someone to test the commit.
-
Thanks for the last commit Sonkun. I will try it on my RPi this weekend! :)

Don't think so. Only the Linux Opengl es implementation is now available (latest commit).
But here is the fix for the android text issue:

Your command line is wrong. To set a define on the command line you'll have to make sure to start with a "D" (for define):
cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/android.toolchain.cmake -DANDROID_USE_STLPORT=1 ..
-
inserted the D there and now I have different issues. I consider myself pretty computer savy but not overly so on Linux so I am trying to track it down as much as possible....but this is what i am getting now

CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!
I know that is a lot to look at so here is what I figure out about it so far on my own. All those initial warnings looks like they are looking for the compilers in the NDK directories but for some reason it seems to be looking in a linux-x86_64 directory which wont exist in that location for any of those since I am on an x86 system (actually in WMware Player) and only have the linux-86 directory there because I downloaded the x86 NDK from the Android website.
So it looks like it goes through all the folders i guess looking for a compatible compiler but it cant find one do to the fact that the folder it tries to look in doesnt exist. And since it cant find one, it is unable to set all the variables at the bottom of that error list.
I know overall the NDK works as I can do a simple project using the ADT and use native code on my own making some OpenGL calls with success.
Anyone have had a similar issue? I been trying to hack through this most of the day and am about to go back and give it a shot in Windows but am trying to teach myself Linux stuff at the same time so would like to develop in that system to become more familiar with it.
EDIT:
It seems if I run the same command twice consecutively, the second time it looks in the linux-86 directories and gives warning on a few of the directories but seems to find some of the compatible compilers and is therefore able to set those variables and it reports "Configuring done" and "Generating done".
I then try the make -j8 command and get the following

errors in building the actual libraries
-
There's something going wrong. I'd suggest you clear your build directory by hand and try once again. Maybe the first attempts screwed up something. Or did you do that already?
-
yeah i have tried multiple times deleting the entire build directory and starting over from scratch with the same results.
-
arm-linux-androideabi-g++: error: SONAME_FLAGlibsfml-system.so: No such file or directory
Same problem here.
-
Can't test is right now, but looks like a typo in the code (like missing space or something similar).
-
it it helps i am using cmake version 2.8.7 from the command line on Ubuntu 12.04
-
so it appears i finally got success in using cmake and compiling sfml for android....here is what i found out should others have the same issue.
1 - I was initially using cmake 2.8.7 and was having all of those problems and errors outlined in my first post
2 - I then put some message statements into the cmake toolchain file and realized that it wasnt pulling in the ANDROID_NDK environment variable i was setting from the command line so as far as cmake was concerned the path to the ANDROID_NDK was "". So I just added that variable on the command line to cmake and was able to cmake successfully
cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/android.toolchain.cmake -DANDROID_USE_STLPORT=1 -DANDROID_NDK=/home/daniel/Desktop/programming/android/adt-x86/ndk-r9 ..
3 - but at that point I would then try to do the make but would receive errors in the compilation process due to the SONAME_FLAG issue that was detailed in the other post. I did some googling and people recommened to update cmake to at least 2.8.9 to fix that issue
4 - So i go to the cmake website and get the latest version of 2.8.12 and installed it
5 - I then went back and deleted my build dir and recreated it empty and ran cmake again.....now cmake would give errors about unable to find certain files and I found that it was putting its version number (2.8.12) into that path of where it expected some of the cmake files inside the SFML drectories
6 - I then went and downgraded to cmake 2.8.9 and started this process over again
7 - this time success with cmake and make to build the libraries
8 - now i did still have to specify the ANDROID_NDK on the command line for cmake as for some reason it wouldnt pick up the environment variable of the same name i would export right before doing the cmake
hopefully anyone else running into this problem then this will help them out
now my next task is figuring out how to get the sfml into my programs. I have already been doing some NDK stuff on my own with raw OpenGL so I have figured out a little of it. I also dabbled with SDL2 when I was hitting these brick walls with SFML and successfully got it setup, but I much prefer the c++ interface of SFML so I came back to give it another shot in compiling it and success this time.
If anyone has a step by step process to use SFML in an eclipse project then let me know.
-
Tried testing on x86 emulator with the following results:
1. Creating a pbuffer with 0 size (which is the default if no params are specified in the attribs) results in an EGL_BAD_ALLOC error and crashes the app.
2. I could not get it to load an image successfully. new priv::ResourceStream(filename); in Image.cpp:134 causes: Fatal signal 11 (SIGSEGV)...
When not trying to load textures, the rest works as expected.
EDIT: Tried the same thing for arm on an actual device (galaxy s4) and get a similar problem. It gets fatal signal 11 at 0xdeadbaad, so somewhere something uninitialized is used it seems.
-
After testing some devices it's clear that the pbuffer problem only happens on some devices. Creating it with size 1x1 solves it for all devices.
My seg fault problems was due to main creating a temp std::string to call things like Texture::loadFromFile and Music::openFromFile. I don't know much about these things but it looks like a library linking issue. Adding a new method that takes a const char* and forwarding it to the std::string version solves the problem 100%.
Also, I'm new here and would like to know if I can log bugs somewhere or send pull requests or anything else to help out.

Hi,
Am I the only one getting an error message telling that 'EGL/egl.h file not found', when building for iOS?
I've looked through the whole post, and it doesn't seem that anyone else have the same problem.
I'm running OSX 10.9 Mavericks, iOS 7 on x64 simulator.

I have the same issue (and the same system configuration).

hello! I'm new to the forum and I'm doing some testings on ios and android ports in order to make a cross platform framework.
I'm building sfml in my own makefiles and building only window and system modules in libsfml.a on windows using mingw: these are my compilation flags:
DEFS= -DSFML_STATIC -DSFML_OPENGL_ES -D__STDC_FORMAT_MACROS -D__USE_BSD -D_BSD_SOURCE -DPOSIX_SOURCE -DGL_GLEXT_PROTOTYPES -Dfdatasync=fsync -DPIC -fPIC -fexceptions -frtti -std=gnu++11
LDFLAGS = -lGLESv1_CM -lGLESv2 -lstlport_static -lc -ldl -lgcc -landroid -lEGL
CFLAGS = -shared -LC:\android\ndk\sources/cxx-stl/stlport/libs/armeabi-v7a -LC:\android\ndk\platforms/android-17/arch-arm/usr/lib C:\android\ndk\platforms/android-17/arch-arm/usr/lib/crtbegin_static.o -nostdlib -Wl,--no-undefined -Wl,--whole-archive libsfml.a -Wl,--no-whole-archive
everything goes ok in window and linux but once I try android things gets hard: I managed to compile and make an apk but when I run a simple main creating a window and displaying a cube, I get a black screen in emulator. in particular eglCreatePbufferSourface returns egl_bad_alloc. I tried to fix it using some custom attributes list: no more errors but still I get black screen with eglSurfaceAttrib not implemented.

I also got the EGL_BAD_ALLOC, and setting the width and height to 1 in the attribs for creating the pbuffer solved it for me and rendering continued as normal.
-
I could manage to display some graphics using the sfml-graphic module: I rendered a blue rectangle on white background on android. so probably the problem is in my opengl setup! dunno where tho
-
ok I got it working! it was a problem on my opengl code! still have to figure out what! probably some unimplemented feature of opengl es! btw eglCreatePbufferSourface really need another type of initialization!
Window/EGLContext.cpp: line 86:
- EGLint attrib_list[] = { EGL_NONE };
+ EGLint attrib_list[] = { EGL_WIDTH,1,EGL_HEIGHT,1,EGL_NONE };

There's no audio module on iOS, I'm still waiting for libsndfile to add a license exception for iOS so that I can use it statically without breaking the terms of the license. The author said it was one of its priorities, but it was months ago and I've got no news...
Well, great news in general, but do you have any hint that the author will add this exception, because i found a quote of the original developer on stackoverflow where he mentioned that he is quite happy with LGPL and when asked if he could make an exception for someones iOS game, he answered with something similar like 'i could do that but then i would have to track down every developer who has commited something and i won't do that'
So unless you have got some hint from him, that he will do it, i would not count on it.
I personally could live with throwing out libsndfile and just limit audio format support to ogg/vorbis, which is bsd licensed.
-
So unless you have got some hint from him, that he will do it, i would not count on it.
He said it to me personally by e-mail. And it was of course after he wrote that post on stackoverflow. But... it was strange that he changed his mind so quickly, so maybe it was just a way to get rid of me ;D
-
No joy so far. I can compile the android port without problems and I can run all the samples that come with the NDK on an AVD and on my phone but I cannot run the sample that comes with the android_and_IOS port. When I try to run it on either an AVD or on my real Nexus 4 it starts and then says "Unfortunately, SFML has stopped."
Building the project seems to work fine. Here is the output from ~/android-ndk-r9/ndk-build:

I believe I configured cmake properly, but I attached a screenshot of my cmake-gui configuration.

Ican use the program with a white screen and song.
In the logchat :
E/libEGL(930): called unimplemented OpenGL ES API
And when i use OpenGLES emulation :failed to create/resize pbuffer
at start and it just crash.
I think Android wanted to use 2.0 OGL and SFML wanted to use 1.0 but didnt find how to solve this problem.
And i must check OpenGLES emulation.

try this patch
Window/EGLContext.cpp: line 86:
- EGLint attrib_list[] = { EGL_NONE };
+ EGLint attrib_list[] = { EGL_WIDTH,1,EGL_HEIGHT,1,EGL_NONE };

Thank you for this tips, but this change nothing for me :-\

Hi,
It's been quite a long time since I last answered here because I was busy with other stuff. I'll be back next week to carry on working on the Android port and answer your technical questions. :)

This was the key for me to get the example project working. Thanks!

One question. Is the audio working perfectly in IoS?
-
There's no audio on iOS. I'm still waiting for libsndfile :-\
-
What a drag...
Anyway, all I ever need(most likely) is .ogg, guess i'll write a decoder just for it or something :x I think I shouldn't get my hopes high waiting for them right? :p
-
You are no longer forced to use "sfml-example" as library name for your application. The SFML activity now reads the manifest file which comes along with your Android project in order to retrieve it, thus you need to add the following line to AndroidManifest.xml:
<meta-data android:name="sfml.app.lib_name" android:value="myCustomLibraryName" />
If you forget it, an error saying "No meta-data 'sfml.app.lib_name' found in AndroidManifest.xml file" will appear.
By the way, I'm still working on the gnustl support to enable C++11 features in your applications. :)
-
Aye! :D Just found out what goes wrong when using the GNU implementation of STL! I'll drop stlport in favor of gnustl shortly so we can enable C++11 in our app! I hope it will also fix SFML not working on some Android device by the way...
Tomorrow, I'll fix the transparency issue properly so you won't have to modify GlExtensions.hpp manually anymore. :)
-
Does that include crashes on Nexus 5? Sounds interesting. :)

I've finally menaged to build ogre over sfml and cegui over ogre on windows mac Linux android and iOS! now I have one last problem with android! when I show the keyboard with
sf::Keyboard::setVirtualKeyboardVisible(true)
I can see the virtual keyboard but I can't capture inputs!
I tried to investigate in the method
int WindowImplAndroid::processEvent(int fd, int events, void* data)
that is attached to a looper in
static void onInputQueueCreated(ANativeActivity* activity, AInputQueue* queue)
but when I try to press a key processEvent callback is not entered! the only keys that works are tab and backspace!
-
little update: I updated android and now processEvent get called but I still cannot have input since getUnicode() in
void WindowImplAndroid::processKeyEvent(AInputEvent* _event, ActivityStates* states)
always returns 0!
-
I'd like to signal the bug I've found on Android! It's quite important since otherwise the app will crash sooner or later:
in WindowImplAndroid.cpp
301 + lJavaVM->DetachCurrentThread();
504 - case AKEYCODE_DEL: return Keyboard::Delete;
504 + case AKEYCODE_DEL : return Keyboard::BackSpace;
593 - jobject ObjectKeyEvent = lJNIEnv->NewObject(ClassKeyEvent, KeyEventConstructor, (jvalue*)downTime, (jvalue*)eventTime, (jvalue*)action, (jvalue*)code, (jvalue*)repeat, (jvalue*)metaState, (jvalue*)deviceId, (jvalue*)scancode, (jvalue*)flags, (jvalue*)source);
593 + jobject ObjectKeyEvent = lJNIEnv->NewObject(ClassKeyEvent, KeyEventConstructor, downTime, eventTime, action, code, repeat, metaState, deviceId, scancode, flags, source);
602 + lJavaVM->DetachCurrentThread();

Hi,
I'm running 64bit Windows 8 and am having trouble with the initial setup.
I've managed to get the basic native-activity sample from android built using the command line, but am having difficulty setting up SFML for Android.
I've never used cmake before now so I'm not sure if I was doing it right, but I'll run you through the steps I took.
1. Downloaded the android-ndk
(Placed in C:/NVPACK/android-ndk)
2. Cloned the repo, and switched to the ios & android branch
(Placed in C:\Users\Matthew\Documents\GitHub\SFML)
3. Downloaded cmake 2.8.12.2 and ran the cmake-gui
3.1. Set source as C:/Users/Matthew/Documents/GitHub/SFML
3.2. Set destination as C:/Users/Matthew/Desktop/AndroidSMFL
3.3. Clicked configure
3.4. Specified generator as Visual Studio 10 with custom toolchain file for cross-compiling
(Toolchain at C:/Users/Matthew/Documents/GitHub/SFML/cmake/toolchains/android.toolchain.cmake)
3.5. Finish
3.6. (Receive error Could not find neither Android NDK nor Android standalone toolcahin.)
(Must specify ANDROID_NDK)
3.7. Added entry ANDROID_NDK as FILEPATH; C:/NVPACK/android-ndk
3.8. Ticked ANDROID_USE_STLPORT
http://i.imgur.com/Kq8hJaU.png (http://i.imgur.com/Kq8hJaU.png)
3.9. Clicked configure again
http://i.imgur.com/RPG1Giq.png (http://i.imgur.com/RPG1Giq.png)
3.10. Clicked generate (no errors)
Contents of build location;
http://i.imgur.com/f86JLsy.png (http://i.imgur.com/f86JLsy.png)
4. Downloaded cygwin64 with make
(Placed in C:/cygwin64)
4.1. Ran the following command;
C:/cygwin64/bin/make C:/Users/Matthew/Desktop/AndroidSFML
Failed
http://i.imgur.com/bAJRTlV.png (http://i.imgur.com/bAJRTlV.png)
4.2. Ran the following command;
C:/cygwin64/bin/make install C:/Users/Matthew/Desktop/AndroidSFML
Failed
5. Instead opened the C:/Users/Matthew/Desktop/AndroidSFML/SFML.sln using Visual Studios 10 Express
5.1. Right clicked on the INSTALL project and clicked Build
Failed
Build log - http://pastebin.com/raw.php?i=qMRXSXAt
5.2. C:\NVPACK\android-ndk\sources\sfml after INSTALL build was as follows;
http://i.imgur.com/AAru0cn.png (http://i.imgur.com/AAru0cn.png)
(Images were large so I left them as links)
As I said I don't have much experience with cmake or the like, so any help would be greatly appreciated
Thanks,
Matthew

First, uninstall Cygwin, unless you need it for something else. The tools in the cygwin package most likely won't like classic Windows path or they'll just pass the wrong paths (i.e. Cygwin paths).
First, install MinGW:
- Download and run the setup program/package manager: http://sourceforge.net/projects/mingw/files/Installer/mingw-get/mingw-get-0.6.2-beta-20131004-1/mingw-get-0.6.2-mingw32-beta-20131004-1-bin.zip/download (the default selection should be enough; you'll only need make)
- Go to MinGW's bin folder and copy mingw32-make.exe to make.exe.
- Add MinGW's bin folder to your PATH environment variable.
- Open a new dos shell (cmd).
- Run "make" - it should spit out an error about not finding a makefile rather than the system being unable to find make.
- Go to your SFML source dir.
- Create a new build folder and then enter it: mkdir abuild
- Now run Cmake (you'll have to add its path in case it's not set): cmake -G "MinGW Makefiles" -DANDROID_NDK=C:/NVPACK/android-ndk -DANDROID_USE_STLPORT=TRUE -DCMAKE_TOOLCHAIN_FILE=../../SFML/cmake/toolchains/android.toolchain.cmake <any other cmake flags> ..
- Cmake will either complete or bug out once, I'm not sure why this happens and haven't had any time to have a closer look. If it bugs out, rerun it and it should finish.
- Now you're ready to build. Run make install and the library files should be built and then copied to your NDK's source directory.
- To rebuild new revisions or changes, just repeat the very last step, then rebuild your projects.
-
Thanks, this helps a lot.
However I now have problems during the make install process,
I used the cmake-gui and had CMAKE_MAKE_PROGRAM set as C:/MinGW/bin/g++.exe
(Built it to C:/Users/Matthew/Desktop/AndroidSFML using the gui)
Then when I ran 'make install' in the directory this happened;
http://pastebin.com/raw.php?i=t4ErTTLN (http://pastebin.com/raw.php?i=t4ErTTLN)
Edit:
Changed STLPORT to disabled and it compiles but then crashes with no errors as Sonkun said it would
(Only crashes when trying to load in assets, otherwise runs fine.)
-
I'd just like to report a bug with the onContentChange method on MainAndroid.cpp
Around lines 318-319:
event.size.width = ANativeWindow_getWidth(states->window);
event.size.height = ANativeWindow_getHeight(states->window);
You're getting the size incorrectly. In certain devices, such as Amazon's Kindle Fire, the window is moved up and resized by the action bar, causing it to e.g., change the size from 1024 height to 1004 height. In this case, however, ANativeWindow will get the old value (1024) while the Rect parameter passed to onContentChange has the right value (1004).
I replaced these lines with the following:
event.size.width = rect->right;
event.size.height = rect->bottom;
-
Which version of the Android NDK should I be using for this? r9d, and (I assume) 64 bit given I'm on a 64 bit Windows 7 system. I have VS2010 too.
-
Any release 9 should be fine. The current instabilities/crashes aren't directly related to the NDK as such (e.g. on the Nexus 5 context creation crashes with the given/default parameters).
-
Hi guys!
Sorry I'm so late in answering you. Finally, it turned out I hadn't fixed the problem and I was still getting weird errors at random places. Actually, I spent the entire last week trying to make SFML work with the GNU version of STL. I just tried everything but it was unsuccessful :( That's why I'm quite delayed here.
Hopefully, yesterday I noticed a new NDK version has been released in the meantime and this one contains a new STL version (the one used by Clang compiler). Thus I dropped everything, GNUSTL (can't make it work, license constraint) and STLPORT (poor C++11 support, upstream development is dead), in favour of this one which has high c++11 support and no license constraint. It seems they're willing to retire the other STL versions as well. Well, I could make SFML work with this version of STL and I'm happy to announce you can now use C++11 in your application and distribute them freely. :)
I will still annoies you with the Android CMake toolchain because it needs to be rewritten to remove features that SFML don't need and which are hard to maintain. Using this new implementation of STL requires the latest NDK version because earlier versions don't have it. However I'll keep the same interface, you just won't need to enable ANDROID_USE_STLPORT but I might introduce new bugs :s.
The good news is SFML now works on some of my devices where it used not to work. What about yours ?
@LittleCodingFox and @nero81af: Thank you very much for reporting bugs. I'll check them as soon as possible!
-
Is it checked in already? Have to have a look. :)
As for my Nexus 5, the context creation with 1x1 pixels fixed the startup crash. Not sure about other devices though.
Edit:
Fixed some tidbits (pull request incoming right now). Compiles fine for me, although this version OpenAl crashes on my Nexus 5. It compiles and runs fine if I don't use the Audio module.
-
on Android, how to detect if the player presses the back button or the menu button? the Home button is really handled by the OS itself and suspends your app, but in other games the back button can be used for menu navigation among other things. I cant find the way to detect that event.
-
As far as I know buttons (hardware and virtual) aren't implemented yet and get just dropped. E.g. you can't use volume control while an SFML app is active.

Hi,
Am I the only one getting an error message telling that 'EGL/egl.h file not found', when building for iOS?
I've looked through the whole post, and it doesn't seem that anyone else have the same problem.
I'm running OSX 10.9 Mavericks, iOS 7 on x64 simulator.
/Kenneth
I have the same issue (and the same system configuration).
I also have this issue on the same system configuration.
-
Hi all! I'm running into the issue where the app crashes right off the bat without any errors. Both on a Nexus 4 emulator and on a Nexus S device. I believe it has to do with not launching the native activity.
I'm using the r9d release of the ndk, with the latest version of the ios_and_android branch, but I still tried building it with and without -DANDROID_USE_STLPORT=TRUE after I couldn't get it working the first time.
I believe it has to do with not launching the proper activity at the beginning, because I didn't see any similar errors with the ndk native activity example.
Is there a way for me to diagnose if it's something wrong with my SFML build or with my project settings?
--Additional Information--
Using Android Studio on Windows 8 64bit
I built SFML with 'cmake -G "MinGW Makefiles" -DANDROID_NDK=C:/android-ndk-r9d -DCMAKE_TOOLCHAIN_FILE=cmake/toolchains/android.toolchain.cmake'
'make install'
I'm using Android Studio, but have the project set up the same way as the native activity example, so I don't believe that is the problem.
I also included my Android Manifest file, thinking it might simply be a problem in there. It's slightly modified from the sfml example. The important part to note is that android.app.lib.name corresponds to libsfml-activity.so, and sfml.app.lib_name corresponds to libapp.so, which are both in libs/armeabi/.
-
Try disabling all parts of the code related to the Audio module. As far as I know it seems to be some incompatibility with the precompiled OpenAL library.
-
Thank you! Looks like that was it, in addition, I'm now seeing relevant messages in my logcat console as well, so it should be easier to debug problems now.
I had actually tried removing them all before, but sfml-activity would error out if I didn't include the audio and network shared libraries in the apk.
Just in case it's helpful, this is the logcat error when attempting to play the audio in the example app:
03-23 18:07:25.097 8680-8697/com.leafdj.app A/libc﹕ Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 8697 (.leafdj.app)

It seems building for iOS is broken at this point. But I successfully build https://github.com/SFML/SFML/tree/7ba4458bea396434eb29b0e1cc19fe0104747d1c

-
I've identified the problem, it should be fixed soon.
Thanks for the feedback.
-
I've identified the problem, it should be fixed soon.
Done. The EGL stuff should no longer cause errors on iOS.
I've also reviewed the sensor API, it's not tested yet on iOS and has to be rewritten on Android (should be done quickly).
-
Regarding the iOS audio issue, since there's no sign of a licensing breakthrough from libsndfile, how hard would it be to reimplement that part of the module using some other library, like the AVAudioPlayer class that the iOS SDK comes with? (I don't care about the exact range of file formats we get, as long as it's better than just .wav)
-
It would require a major internal redesign.
-
Should the Android example to work now? I built it with armeabi-v7a and it crashes on start.
-
Try commenting out all SFML Audio related lines and it should run just fine. It's the precompiled library that somehow screws up.
-
Yes, thank you, it works now. Cool! =)
So i need to build audio libs myself?
-
It might help, haven't tried it so far, since compiling OpenAL for Android doesn't seem to be too trivial to do. :(
-
As i remember that task was in my practice a year ago. It was part of an engine of one software company which hired me to outsourcing. I forgot everything, but it was pretty simple. Or it was not OpenAL? =) I need to learn all stuff from the very begining...
Yes, i even found MK from it:

Yep, building of latest OpenAL from repo is not so simple. At the current moment i'm stuck with two things: 1) tons of multiple definitions, 2) i don't know why am i doing it. =)

Make sure you've got the proper module name set for the native ability. Right now it's still looking for "sfml-activity" rather than whatever you've defined.

I'm not sure about build.gradle, no, i'm sure that my build.gradle is incorrect. Google changed project's structure in Android Studio again! So, this question is not for this topic, it's for Google. Is there full AS documentation anywhere?

Well, in Eclipse all builds perfectly. Another question, how to buld SFMLES with gnustl_static?

It shouldn't. Make a clean build to be sure ;)
-
Well, may be, i'm mixing with SFML and SFMLES, so i can't be sure absolutly. sf::String, for example, i copied from main branch.
-
You shouldn't have to do any modifications on your own, just grab the ios_and_android branch off SFML's main repostiory on GitHub. You might just have to skip SFML audio for now.
-
Getting familiar with the compilation process of native Android application isn’t an easy task so, don’t give up and read carefully the NDK documentation. Maybe you should start with compiling an official example such as NativeActivty located in your NDK. You’ll need to get through this because you won’t be able to reuse this CMake toolchain script to compile your own application (unless your application is a library :D).
Since I don't have the time, to search and teach me all the things around Android and NDK and yet, still would like to test the Android port, is there an easy and at best step by step guide for this?
-

There was some trouble with String. I'll check now, where i went wrong.
-
Here it is:
error: 'class sf::String' has no member named 'toUtf8'
-
sf::String::toUtf8() was added after SFML 2.1, and it seems not to be part of the ios_and_android branch yet.
By the way, ChronicRat, please use the Edit function if you're adding information to a previous post. Earlier you posted 3 posts and 4 posts in a row; it really makes the thread unnecessarily long and more difficult to read. Users are also notified if you edit the post.

I just rebased ios_and_android branch onto master thus to update your local branch git pull won't work, you'll need to recreate it.

Just pulled repo. Error in building armeabi-v7a.

No questions to SFMLES now. =)
As i understand, there is no way to get locale from C. So i think, such method must be implemented in SFMLES. Or may be better is to create some sort of wrapper to allow programer fast bind to java... Well, it is just variant, i have not thought through this.
And AAssetManager must be available with SFML methods.

Yes, i can turn off music in example, but i can't turn off music in my game. So this bug is critical, i will try to resolve it myself if Sonkun is busy. And another bug - program crashes or hang ups when rotating phone i.e. crash on screen rotation. Is it tries to recreate window?
-
Of course that's no permanent solution, just a temporary workaround for testing.
Edit:
As for the build error, you can use this commit:
https://github.com/MarioLiebisch/SFML/commit/b8c2cdcfbc10d76db7cdb2a9f5fa0c544b497ad6
Edit 2:
Why no locale in C? Never tried using setlocale() on Android, but it should be available.
-
Yes, Joystick i fixed already, but i did not declared class member, just return Joystick::Identification();
setlocale returns nullptr. Google said that there is no access to current locale from NDK.
And i built the most fresh OpenAL from repo - no crash on sound play now. I'm just replaced shared object (openal.so) in $(NDK)/sources/sfml/ext-libs and rebuilt Android example - sound works.
First run: broken graphics and no reaction on touch. i'm not implemented using of sf::Touch yet.

(i'm not checked, may be with forced C99 there are no need to disable log macros)
#ifdef NO_LOGGING
#define TRACEREF(...)
#define TRACE(...)
#define WARN(...)
#define ERR(...)
#else
#define TRACEREF(...) do { \
if(LogLevel >= LogRef) \
AL_PRINT("(--)", __VA_ARGS__); \
} while(0)
#define TRACE(...) do { \
if(LogLevel >= LogTrace) \
AL_PRINT("(II)", __VA_ARGS__); \
} while(0)
#define WARN(...) do { \
if(LogLevel >= LogWarning) \
AL_PRINT("(WW)", __VA_ARGS__); \
} while(0)
#define ERR(...) do { \
if(LogLevel >= LogError) \
AL_PRINT("(EE)", __VA_ARGS__); \
} while(0)

And you'll need to create own config.h from config.h.in

What exactly this error does mean?
E/libEGL(3472): called unimplemented OpenGL ES API
I don't use any direct OpenGL code, all operations via SFML.
-
I'd say you (or SFML :P) tried to use some OpenGL ES call that isn't implemented in your version of the NDK for whatever reason.
-
Latest NDK, APP_PLATFORM - 10. Test smartphone with Android 4.2.2. What SFMLES need as minimum platform?
And again, what do with shaders? Currently i'm not using shaders, but, in future, may be i can enable GLES2 myself and use own code? Or shaders soon will be in SFMLES?
-
Never had OpenGL ES issues using APP_PLATFORM on 9. Weird. Would you mind sharing your config.h? Couldn't get it to compile so far.
-
Openal-soft config.h
By the way, may be -DIN_IDE_PARSER in Android.mk is useless too after adding -std=c99
-
So, i have several thoughts what i need (and i think others too):
1) access to ANativeActivity to get app path, or asset manager, or make it possible via special Android-only interface.
2) callbacks to Android events (Pause, Start) or make them via SFML events system (for example GainedFocus and LostFocus)
3) bind AKEYCODE_BACK to Keyboard::Escape
4) emulate CTRL+ESC (or any other combination, may be dynamicly changable) for AKEYCODE_MENU
Sorry, if all of this is available now, and just i have to rtfm.
-
Got it working late last night. I've had to use the latest source from their repostirry (OpenAL) and make some minor modifications, but it's working and it's quite small as well. :)
-
Mario, is sf::VertexArray supported by SFMLES? In my game does not work VertexArrays, Fonts, RenderTextures and sprites has no transparence. :o
-
sf::VertexArray should work, I've been using it myself. You just can't use Quads. Is it possible that you're using them?
-
No, i'm using all sorts of Triangles.
-
I tested sf::Font in "example" - it does not work, i don't know why yet. Transparency in test sprite does not work too. Just clear window with non-white color - it is immediately obvious.
loadLibrary("sfml-system", lJNIEnv, ObjectActivityInfo);
loadLibrary("sfml-window", lJNIEnv, ObjectActivityInfo);
loadLibrary("sfml-graphics", lJNIEnv, ObjectActivityInfo);
loadLibrary("sfml-audio", lJNIEnv, ObjectActivityInfo);
loadLibrary("sfml-network", lJNIEnv, ObjectActivityInfo);
In debug build this code is incorrect.
Retrived sf::Err() output:
sf::Quads primitive type is not supported on OpenGL ES platforms, drawing skipped
Indeed, Mario, somewhere i'm using quads. But this is only part of render problems.
-
Yes, fonts are broken for me as well.
-
Fonts and transparency, Mario! No transparency everywhere, in all gfx objects.
-
Ah, didn't use transparency so far. That might actually be the same issue then (didn't check whether it's glyph rendering to textures or the rendering to screen). At least glyph dimensions are correct.
-
I fixed sf::Font.
For the transparency issue, in file src/SFML/Graphics/GLExtensions.hpp line 37, you can replace "GL_OES_blend_func_separate" with "false". It shoudl fix your issue. I don't know yet the proper fix.
-
Thanks, now it's much better:
(http://cs616521.vk.me/v616521616/9f62/LWZDxwJ68bE.jpg)
Now i have two questions: what to do with notification zone? Iit eats part of screen, where i have buttons. How to react on screen rotation? Need i to do it myself or it will be SFMLES's job?
But first of all it is necessary to LostFocus/GainedFocus events.
-
Screen rotation should be nothing more than a resize event. If Jonathan did it like on iOS, it should work out of the box.
-
Oh, i was not tested game with single threaded mode. It can't active RenderContext after resize, so if in single threaded will be ok then it is my fault.
upd: Nope, single threaded can't activate context too.
-
Screen rotation should be nothing more than a resize event. If Jonathan did it like on iOS, it should work out of the box.
It worked before, but with the latest version my screen freezes sometimes (with the example app). Going to standby and back on the phone reacts again but the SFML screen stays black. Doesn't seem to happen all the time though. Didn't have time to try to track it down so far.
But yes, overall, rotation should be a resize event and it worked before.
-
Must sf::RenderTexture work in SFMLES?
-
sf::RenderTexture works for me.
As for the resize event bug, I'm working on it :)
-
Ok, and by the way VirtualKeyboard works only for latin text.
If i'll catch bug with sf::RenderTexture - i'll inform.
-
After merging ios_and_android with master fonts are broken again.
And AKEYCODE_DEL must be returned as backspace.

I'd like to submit here some patches I had to put in sfml in order to build ogre with sfml on android ios macos linux and windows with gl3plus renderer and gles2 renderer and mingw64 compiler. Some patches allow the creation of a es2.0 / 3.0 context.. not sure those are useful tho since sfml is working with gles 1.0 only.. anyway here they are (those patches should not broke actual build)

Regarding the OS X part of your patch, the current master revision should already address those issue. Can you confirm that?
-
those patches have been applied on the master branch from yesterday so no! opengl 3.0 context does not work without those patches
-
Then there's some duplicate code. https://github.com/SFML/SFML/blob/master/src/SFML/Window/OSX/SFContext.mm#L189-L202 and https://github.com/SFML/SFML/blob/master/src/SFML/Window/OSX/SFContext.mm#L215-L232
You can create a pull request on github if you want. It will be easier to integrate your work then.
-
I edited my previous post! master branch has fixed problems regarding opengl 3.0 context creation.
while testing I found out another bug
JoystickImpl.mm and JoystickImpl.hpp in Ios folder are missing getIdentification method!
-
Sonkun, did you solved rotation bug?
-
Sorry, actually I'm on vacation and I didn't have enough time to find out the bug or answer the forum. I'll have time to work on SFML Friday evening and whole Saturday. I hope it can wait.
-
Yes it can wait surely. =)
-
@nero81af: your patch sounds interesting. However it turns out I don't have enough time (because of the SFML team reorganization and the amount of discussion to read/reply) analyse and merge it. As for the rotation bug if you want to solve the bug, go ahead I would be glad to merge your changes. Otherwise, I'll be back on 28th of April thus I hope I can do it day after.
-
I've made a little hack:
AAsset* GetAsset(const std::string& filename)
{
priv::ActivityStates* states = priv::getActivity(NULL);
Lock(states->mutex);
return AAssetManager_open(states->activity->assetManager, filename.c_str(), AASSET_MODE_UNKNOWN);
}
But i'm getting segfault on open. I cheked that states->activity is not null and assetManager is not null too. What it can be? My own bug, again.
-
Here is log for rotation crash.
I think it's OpenAL again.

Adding "orientation" to manifest fixed crash. But view not changed in example project. My croger controls view itself, so it works on 4.2.x Android.
android:configChanges="keyboardHidden|screenSize|orientation"
As i understand it won't work with Android 2.3.3.
-
Well, who is intrested, can download full android alpha - https://www.dropbox.com/s/409org6py72zkq7/croger.apk
I think it won't run on API < 13 and it crahes on stop/continue, i.e. you can't answer to call or read SMS and then return to game now. Fixed.
Now i see only one serious bug - NativeActivity not killed on exit. And when i'll run game again, there are just black screen, i need to kill app manually then start. Example has this bug too. Looks like onDestroy is not called on window close.
As i understand ANativeActivity_finish() does only mark to wish finish, and app has to be alive while onDestroy is awaiting to be called.
-
Interesting! Actually, I noticed the activity not properly destroyed bug when working on the rotation bug (and that's why I needed more time :p). But I don't understand why we still see the application as running because the code is called as intended. onDestroy() takes care of sending the SFML close event, the main loop ends which ends the main() function, which causes ANativeActivity_finish() to be called.
-
I inserted log messages in the onDestroy function, i haven't seen any message. In the same time messages in the terminateMain was displayed.
-
I forgot to mention I also had to move the clear/draw/display calls to the top of the main loop. Probably something goes wrong when calling them after the window has closed.

Thanks, I fixed it locally with another bug. I'll push everything shortly.
@nero81af: I don't understand the changes you made in the EGL implementation. Why would you need that ? As you said, SFML currently only supports version 1.x of OpenGL ES so it shouldn't be necessary.. unless you can't get Ogre working with SFML without it ?

Don't worry, I am ;)
Sorry for those who are waiting for the changes I announced. I'm delayed because since I rewrote the Android CMake toolchain I can't get libsfml-activity.so to work >.< The audio module is fixed (I managed to compile OpenAL-Soft for Android properly) but I want to recompile libopenal.so again once the toolchain is fixed. There are also small fixes (Raspberry Pi compilation, EGL display is equal to EGL_NO_DISPLAY, etc.) on top of that and I don't want to push before everything works out of the box.

I just want to ask about the feasibility of waiting for libsndfile license changes for iOS.
I remember someone mentioning this in a previous post, but here's the post 2 years ago from Stack Overflow where the person who calls himself the main maintainer of libsndfile states:
Unfortunately libsndfile has lots of copyright holders and I simply don't have the patience to track them all down and ask them if its ok
https://stackoverflow.com/questions/4939268/can-the-libsndfile-library-be-used-on-the-iphone-ios
I'm just wondering if looking into other c++ audio libraries may be more practical.
Here's one I've found while googling that seems to support OSX and iOS (I'm sure there are also others):

E-mail from Erik, 8 months ago:
Hi Laurent,
Dealing with this issue is high on my todo list.
I intend to email all the people who have significant contributions
to libsndfile and ask them if they are OK with a modification to
libsndfile's license.
That modification would be to change libsndfile to LGPL with a
static linking exception on iOS and any other OS which does not
provide support for dynamic linking.
This change keeps the spirit of the LGPL and fixes the issue with
iOS.
Cheers,
Erik
Nothing else since then.
libsndfile is not an audio player. It's just an audio file reader/writer. And no other library does that.
If I redesigned the audio module so that it is more abstract, I could plug other file backends, and easily provide support for at least OGG, WAV and Apple's audio format(s) on iOS.
-
Would you say that this project has already reached a state where I can "easily" port my current game project to Android or are there still to many bugs to publish a real game in the Play Store?

Thanks for quoting the email, it's good to see the reply.
This is just my person opinion, but if libsndfile's license change is something that still doesn't have an estimated date, it might be more worthwhile to, as you've said, first redesign the audio module to allow users to play at least OGG, WAV, and Apple's audio format(s) on iOS.
I feel users' first priority is in actually getting audio to play - most games are nothing without sound, and if the price to pay is some abstraction, I feel that most would comply than go without an entire audio module which in many cases prevents development completely.
If some time afterwards libsndfile does make the license change, then we could perhaps revert back to the original code at that point and remove the abstraction layer.
All in all, I feel this is more a time issue - if libsndfile's license change is unpredictable then I sense that abstracting the audio module to provide users with basic sound play, and reverting the code after libsndfile's license change (whenever that may be) may be a more attractive stance to take.
It may perhaps be worthwhile to send Erik another email to ask if there's been process over the last 8 months.

I've found a bug on Android with texture repeating (using the example) :
(http://img15.hostingpics.net/pics/281991sfmlbugrepeat.png)
The sprite should be exactly 4 SFML logos
Here is the code :
#include <SFML/System.hpp>
#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>
#include <SFML/Audio.hpp>
#include <SFML/Network.hpp>
int main(int argc, char *argv[])
{
sf::RenderWindow window(sf::VideoMode::getDesktopMode(), "");
sf::Texture texture;
if(!texture.loadFromFile("image.png"))
return EXIT_FAILURE;
texture.setRepeated(true);
sf::Sprite image(texture);
image.setPosition(0, 0);
image.setOrigin(texture.getSize().x, texture.getSize().y);
image.setTextureRect(sf::IntRect(0, 0, texture.getSize().x * 2, texture.getSize().y * 2));
while (window.isOpen())
{
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed)
{
window.close();
}
}
if (sf::Touch::isDown(0))
{
sf::Vector2i position = sf::Touch::getPosition(0);
image.setPosition(position.x, position.y);
}
window.clear(sf::Color::White);
window.draw(image);
window.display();
}
}

This is not a bug, only a limitation of your GPU, as stated in the doc:
Warning: on very old graphics cards, white pixels may appear
when the texture is repeated. With such cards, repeat mode
can be used reliably only if the texture has power-of-two
dimensions (such as 256x128).
Admitedly, it's not a "very old graphics card", and pixels are not white. But anyway, your platform (don't know if it's your GPU or the GL ES 1.1 spec) doesn't support non-power-of-two texture sizes. So you can't use texture repeating on such textures.

Hmm, I'm running into errors recompiling SFML after updating to account for the branch merge.
Right now these are the steps I'm taking:
- Using Cmake GUI on Windows:
- Select source and build paths
- Set ANDROID_NDK variable to point to my Android_NDK path
- Hit Configure- Select MinGW Makefiles and specify toolchain for cross-compiling. Point to the SFML Android toolchain.
- Warnings appear saying "Could not uniquely determine machine name"
- Eh, what are warnings? Generate makefiles successfully.
- Try to run make (both the one included with Cygwin and the one packaged with the NDK, neither worked) in the build dir. Get's to 66% then errors out saying "GL_FUNC_ADD was not declared in this scope"
I was able to build the SFML libs properly for Windows, though that was with running the make included with the Android ndk, which generated a Visual Studio solution that I used to compile it. I previously had the android implementation compiling too, and I don't think I'm doing anything differently this time around.

This is not a bug, only a limitation of your GPU, as stated in the doc:

http://pastebin.com/Be4jJjUs
Thanks, I fixed it locally with another bug. I'll push everything shortly.
Have you pushed it? It appears to still be broken. It looks like the issue is that GL Blend functions arnt supported in GLES 1.x, and SFML uses the GLES 1.x headers in OpenGL.hpp
-
The current master branch does not compile for iOS. I have generated build scripts with the IOS parameter set to true.
JoystickImpl member getIdentification is missing (I see the android version for this was fixed a month ago). In addition I get a couple of GL related errors (ss attached).

I thought it was already fixed... I'll take care of that ASAP.

There's still a pull request up done by myself, which should fix building on all OpenGL ES platforms: https://github.com/SFML/SFML/pull/580
You don't have to wait for Laurent, just copy the few lines and apply the changes yourself.

Admitedly, it's not a "very old graphics card", and pixels are not white. But anyway, your platform (don't know if it's your GPU or the GL ES 1.1 spec) doesn't support non-power-of-two texture sizes. So you can't use texture repeating on such textures.
What do you think? Should the unused areas be filled with some pattern or collor? I'd probably make them magenta?
-
There's still a pull request up done by myself, which should fix building on all OpenGL ES platforms: https://github.com/SFML/SFML/pull/580
If you make it into a separate pull request (without the Android CMake stuff), and follow the naming conventions (just have a look at all the other identifiers of the GlExtension.hpp file), we can probably merge it quickly ;)

It doesn't matter, because these parts should never be shown.

Happy now? :) Otherwise just comment on the PR.

Okay, true.

No ;D
You PR no longer matches its title and description. You should at least add a message that explains what you changed.

Nitpicka! Fixed. :)

What do you think regarding the Android sensor implementation? I don't know any reason why the ndk headers haven't been updated, but based on the API version (any minimum defined so far? I'd suggest 9 or 12) pretty much all sensors should be available (http://developer.android.com/guide/topics/sensors/sensors_overview.html#table2), even if they're lacking official enum members. For example, the gravity sensor is missing from the official headers, but it's working without any issues (tested on Android 4.4 though).
Apart from those listed already, I'd consider the following sensors to be quite interesting for some games or possibly utility/entertainment software as well: TYPE_LIGHT, TYPE_PRESSURE, TYPE_PROXIMITY, TYPE_TEMPERATURE.
-
The set of exposed sensors has been reduced on purpose. Let's start with a small subset of the most common sensors, and add others in future versions.
-
Okay, the source comment gave me the impression they've been left out just due to (possibly outdated) docs.
-
Which comment?
-
// These sensors are unavailable from the Android C API
if ((sensor == Sensor::Gravity) ||
(sensor == Sensor::UserAcceleration) ||
(sensor == Sensor::Orientation))
return NULL;
-
Hmm... yes, looks strange.
-
sf::Music and sf::Sound aren't work on Android for me, is this an known issue? Because everytime I create a instance of Music or SoundBuffer the app crashes (segment fault 11)
AlexAUT
-
That might be related to https://github.com/SFML/SFML/issues/621.
-
That might be related to https://github.com/SFML/SFML/issues/621.
Yeah this fixed my issue.
Another Question: Is it intended that SFML "eats" the volume keys events? Because it's quite annoying when you have to switch out of the app to change the volume of the game.
AlexAUT
-
Yep, right now it does (and it won't generate key events in SFML). Should probably be something that should be changed for 2.2.
-
Yep, right now it does (and it won't generate key events in SFML). Should probably be something that should be changed for 2.2.
Yeah i changed the source of SFML so the hardware keys (back, volume) send a key event. Simply added sf::Keyboard::Back, sf::Keyboard::VolumeDown. Without these keycodes its nearly impossible to make a game.
Edit: Is there any "real" case where the app should catch the volume keys?
AlexAUT
-
Added an issue for this: https://github.com/SFML/SFML/issues/622
There could be use cases where you'd like to control something with the volume keys. Take Amazon's Kindle app as a prime example. It doesn't provide sound output by default. As such they're using "volume up/down" as "page up/down" while reading text, which works rather nice. Of course, there's the touch screen as well, but it's just another option.
It's also possible to use Android phones with VR toolkits such as the Durovis Dive (https://www.durovis.com/index.html). Once the phone is strapped into the thing it's rather tedious to still access the touch screen, but you could provide minimum control through the (still accessible) volume keys.
-
Thanks for the examples.
I just noticed that ogg files are still cracking when playing them on android :'( . I don't want to use wav 8)
Edit: Normalizing the audio removes the cracking like described here: https://github.com/SFML/SFML/issues/310

Hi,
I rewrote the Android toolchain and pushed the change in feature/android_toolchain. However, there's still a bug and if you compile SFML using this new toolchain, Android won't be able to launch sfml-activity.so. I hope to fix that bug soon (it has to do with link options).
Regarding the audio module which is broken: it's all about compiling OpenAL-Soft properly. Unfortunately there's no official version for Android and our two options are:
* https://github.com/AerialX/openal-soft-android
* https://github.com/apportable/openal-soft
I couldn't make apportable/openal-soft work and managed to make the other one work after disabling some audio backend. The CMake scripts that come along are also a bit broken and need to be hacked to work on some platforms. I'm just waiting for the new Android toolchain to work before recompiling OpenAL-Soft for each arches.
There's also a bad news about the audio module: I never got sf::SoundRecorder working and I really don't know how to fix that. Thus SFML 2.2 might be released without any audio recorder features working on Android.
-
// These sensors are unavailable from the Android C API

return NULL;
Yes, unless I missed something, these sensors are unavailable from the C API and would require to go trough JNI to use the Java API.

They're only missing from the headers. Using the values from the SDK docs works for me, though.
As for OpenAL, there'd be a third option from a non-github repository. I either linked it here or on the issue tracker. I haven't checked recently, but I think the biggest hurdle is getting a proper config.h (which I have now). Guess biggest question would be which repository us updated regularly (didn't check the ones above so far).
Going to have a look later today.
-

Awesome! I wasn't aware of that. I added the missing sensor constants and made the remaining sensors available. The change can be found in feature/android_toolchain branch.

Does sf::SoundRecorder work with this version of OpenAL-Soft ?
-
Hm... with latest master I no longer get any audio output and then another segfault after a few seconds.
-
Hah! Got it working again (and this time my source and build directories for OpenAL are in a clean and tidy state; I've somehow had quite a mess before). :)
I only had to perform one tiny adjustment:
- Clone the official(?) OpenAL-soft repository from git://repo.or.cz/openal-soft.git (http://git://repo.or.cz/openal-soft.git) (just the master branch is enough).
- Open the CMakeLists.txt file and comment out line 1022:
#SET_TARGET_PROPERTIES(${LIBNAME} PROPERTIES VERSION ${LIB_VERSION})- Create a build directory for each architecture and use SFML master's toolchain file with CMake to create makefiles. (I commented out the toolchain warnings to speed things up.)
- Everything should build out of the box and create the library files in libs/<architecture>. The common.a libs can be ignored.
- Do not use make install, copy the static libraries by hand.
-
when I call ndk-build on the sfml android example i get this error
Android NDK: WARNING: APP_PLATFORM android-17 is larger than android:minSdkVersion 9 in ./AndroidManifest.xml

Sounds like "make install" for SFML somehow failed. Do you have the directory [ndk]/sources/sfml?
-
no I don't have [ndk]/sources/sfml
this is how my cmake-gui looks like
source code: /home/heresh/Downloads/SFML-master/

then i go to where it put the build files and call
make
sudo make install
and everything works fine no errors
-
Ah, you're building and installing the desktop version of SFML I guess. Building for Android is a bit more complicated unfortunately. :) I'll see if I have time to write some short readme/guide for the wiki.
-
Okay, started a new wiki page explaining building SFML for Android (https://github.com/SFML/SFML/wiki/Building-SFML-for-Android). It's still incomplete and might contain mistakes as well. If anyone feels like improving the page, go for it!
-
Very nice Mario, thanks a lot! That will certainly open the Android port for more people, and it could even be used as inspiration for the official tutorials :)
-
Okay now you're talkin' :) Thanks Mario, I needed that stuff :)
-
Hi there,
is there any way to build a GL ES2.0 context? Can't seem to find any solution.
Thanks
-
Nop, at the moment SFML is entirely based on GL ES 1.1.
-
I just need the context, the rest of it is handle by me. Just want to use the window and events with SFML.
-
It is currently hard-coded. On iOS (EAGL) it should be farily easy to turn it into a public option, I don't know about EGL (Linux / Android).
-
That would be great if it could go public option!
-
Hi
I already built SFML-2.1 for android with mingw x32-4.8.1-posix-dwarf-rev3
(http://i.imgur.com/ADWgDNe.png)
It's all I need? I'm quite disorientated and I don't know how to compile my code for android

Yes, I followed this guide, but how to compile?
-
That guide uses CMake, so you tell it what compiler you want and it will generate the appropriate makefile/project file/whatever which you then use to do the actual compilation in whatever way is normal for your compiler. It even gives the example that on Linux the actual compilation would be make && sudo make install. For something like Visual Studio obviously you would open the project file and then tell VS to build the project. Reading the official CMake tutorial might help: http://www.sfml-dev.org/tutorials/2.1/compile-with-cmake.php

I already compiled/built SFML with CMAKE, I mean how to compile my code for android apps to .apk? how to create a project, in code::blocks, for example.
-
how to create a project, in code::blocks, for example.
Well, i'm working on it now. I have no results yet, but i have several thoughts. By the first i copied XML where ARM compiler declared. Then i'll adapt it for NDK toolchain - it's not problem for one single computer. After building source C::B will run afterbuild script which will create APK. So, it looks pretty simple and at least possible. But my main target is debugging code with C::B and i don't know how to do it yet, but think it possible too.
-
Quickly:
Compile SFML using CMake, it should look like this:
export ANDROID_NDK=/path/to/ndk
mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/android.toolchain.cmake -DANDROID_ABI=armeabi ..
make
make install
The last command, make install, will install everything in your NDK (headers, libraries, bootstrap).
From now, just create a regular native Android project (actually, just copy and adjust the example provided in SFML source, it'll be easier), compile and run. Refer to the example to write your app Android.mk and Application.mk scripts. It should look like this:
cd path/to/your/android-project
$ANDROID_NDK/ndk-build # this line compiles your project)
Then press the run button from your IDE.
-
cd path/to/your/android-project
$ANDROID_NDK/ndk-build # this line compiles your project)
Then press the run button from your IDE.
Why not just adding native support to your project (Right-click on project -> Android tools -> Add Native Support) and let eclipse compile your project?
Another advantage, you will have code completion and eclipse will report c++ errors too.
AlexAUT
-
Just a quick question: is there a way to obtain the native activity outside sfml? I need access to obbpath and assetmanager to extract game data! :D Maybe it would be nice to obtain it from getSystemHandle instead of the native window!
-
Not yet.
-
Anyone tried new NDK10? I wonder why $NDK/platforms is empty except "android-L". cmake can't configure make files without "android-9", i copied it, just for test, from previous NDK and cmake configured make files successfully. But, as expected, there were problems with linkage.
-
Just updating and my Platforms folder has all the previous versions. Are you sure you downloaded the correct package? (Windows x64 here)
-
I'm using Ubuntu for building for android. :o Well, i think i can copy these files from Windows package.
upd: Yes, i'd downloaded wrong package. There are new target now - arm64.
-
I can share some hacks for my games. Currently it placed in System/Err.hpp and System/Err.cpp

These things are necessary! I don't know how to say it in english... That functional MUST BE provided by SFML.
By the way, i'm using C::B to build game, and now i'm trying to debug via C::B.
-
I've noticed the same limitation last week, but the whole asset loading is already there, just not exposed. I thought about adding something like sf::String::loadFromFile(). It should still be able to read binary files as well. And most important: The code should work cross-platform. :)
-
I'm using my own ResourceManager, where 99% of files are loaded via sf::InputStream interface. It pretty good to universal reading of data from files or archives and my Lua's "require" is modified to use it, so i need full access to Assets. And I'm not using ::loadFromFile at all. Now i'm using assets just once, when app runs first time it copies game's data files from Assets to app's data dir. To be honest, there are only one "data files" - resource.pak.
By the way, is "orientation" works now? I updated master branch to last state and Android's screen now is vertical only.
-
It should work just fine (triggers resize events). Just check the example app.
-
static void onPause(ANativeActivity* activity)
{
// Retrieve our activity states from the activity instance
sf::priv::ActivityStates* states = sf::priv::retrieveStates(activity);
sf::Lock lock(states->mutex);
// Send an event to warn people the activity has been paused
sf::Event event;
event.type = sf::Event::MouseLeft;
states->forwardEvent(event);
}
Why there used "MouseLeft" event? I think "LostFocus" is better.
But it is not important. I'm entering to this function when i'm exiting from my "main". If i'm calling "window->close()" before - the same. I want to get in "onDestroy" function!
-
I already created an issue about this topic: https://github.com/SFML/SFML/issues/653
The problem is there should be a way to differ if onPause or onStop is called, because maybe you want to do different things.
AlexAUT
-
AlexAUT, do you have any trouble with exiting from app? I can normally launch/exit only once, then i need to kill app manually to launch app again. As i see in the debugger - "onDestroy" function is never called.
-
onDestroy is only called when app gets deleted from the memory, for example when the system is low on memory... So its ok when onDestroy isn't called.
What do you mean with "exiting from app", do you mean when the user presses the home button? Or do you mean when your code closes the app -> main returns?
For the first case I have no problem, sf::Event::LostEvent/MouseLeft are called and sf::Event::GainFocuse/MouseEntered are called.
For the latter case I use exit(0) to close the app, otherwise I have problems when I open the app again.
AlexAUT

Just remember that "exit(0)" won't run any destructors...
-
No problems here either. Works fine as well.
Here's a compiled/packaged version of the SFML example app featuring a simple modification that will print out all events happening, making it easier to see which events are fired: https://dl.dropboxusercontent.com/u/2510538/SFML-Example-debug.apk
-
Just remember that "exit(0)" won't run any destructors...
Yes, I know. =) But I would never have thought of using "exit" to quit app. I just forget about it. Now I can place my games at stores. 8)
-
Just remember that "exit(0)" won't run any destructors...
The problem is what are the options? When I return normally the user can't open the game again, so I created the "engine" on the heap and delete it myself before I exit(0) (btw I have no globals), but I don't know about the SFML global stuff :-\
AlexAUT
-
This sounds like you've got some bug somewhere, possibly a race condition with static constructors/destructors?
-
It also happens with the SFML-example, so I guess its not a problem with my codebase, also it does not happen on every device. Sadly I can't test it because I haven't my phone for ~2weeks (broke it last week :'( )
AlexAUT
-
There used to be a bug similar to that in event handling a few weeks ago. Make sure you actually rebuild from scratch (delete the bin/libs/obj sub dirs), then build again. Just issuing "ndk-build" or "ndk-build -B" doesn't seem to always do the trick.
-
Okay, I will try it when i have my phone back.

Quick question about resource management on Android, I'm having a bit of a tough time reading a .txt file that I have defined in assets. I'm using an ifstream which works fine on Windows, but won't work on Android because the file is contained in the .apk. Is there a way to use the SFML Resource Manager that's used by Image Loading, etc., or is it better just to directly use the android asset manager?
Is there a way that I can get a reference to the file that can be treated the same way as the ifstream?
ie stream >> line?
-
It's not exposed yet, you'd have to write your own code around that. But I'm having the same issue, so very likely to submit something soon™.

Okay, thanks for the reply Mario. Wasn't sure if I was just missing a piece of the puzzle or not. I'll try and tinker with it a bit and see if I can make something work.
-
As a temporary solution, all you'd need would be "src/SFML/System/Android/ResourceStream.hpp" to access `sf::priv::ResourceStream`. No need for further custom code.
-
Ah, perfect. I was trying to replicate the functionality in ResourceStream on my own. I didn't know I could simply move the header file to get access to it. Everything looks like its working, thanks for the help!

Someone else having problems which certain fonts at certaint sizes? Because sometimes sf::Text is destroying the rendering, it looks like the backbuffer doesn't get updated anymore so display will always "show" the last frame and the current frame (in a loop, gamelogic still runs fine). Kinda hard to describe. I had a similiar problem with my opengl engine where I forgot to "unbind" a FBO, looked exactly the same.
Grimmreefer has also experienced this issue so I think it is related to SFML, sadly I can't reproduce it right know (but its still there I changed the font/font-size in Kroniax about 5times to avoid this issue)
AlexAUT
-
I'm not sure about your bug, but may be... All my problems with fonts were with "loadFromFile" or stream's bug. Now i'm using "loadFromStream" only and have no problems with any language.
-
I've been tinkering with SFML for a short while and I'd like to request some assistance and troubleshoot some issues I'm experiencing... :)
I use the bleeding edge master available at https://github.com/SFML/SFML. Here's a short piece of test code.
#include <iostream>
#include <SFML/Main.hpp>
#include <SFML/Graphics.hpp>
int main(int argc, char **argv) {
sf::VideoMode videoMode = sf::VideoMode::getFullscreenModes()[0];
std::cout << videoMode.width << "x" << videoMode.height << "@" << videoMode.bitsPerPixel << std::endl;
sf::RenderWindow window(videoMode, "Test", sf::Style::Fullscreen);
sf::RectangleShape rect(sf::Vector2f(window.getSize().x / 2, window.getSize().y / 8));
rect.setFillColor(sf::Color::Red);
sf::Event event;
while (window.isOpen()) {
while (window.pollEvent(event)) {
if ((event.type == sf::Event::Closed) || ((event.type == sf::Event::KeyPressed) && (event.key.code == sf::Keyboard::Escape))) {
window.close();
}
}
window.clear(sf::Color(sf::Color::Blue));
window.draw(rect);
window.display();
}
exit(0);
}
Android (test hardware, Nexus 5 and OnePlus One):
1. I experience the same issue AlexAUT and ChronicRat with the application crashing when backing out of it. I currently work around the issue by also using exit(0).
2. Crash upon pressing the "Home" button. AlexAUT and ChronicRat, how did you work around it?
iOS (test hardware: iPod touch, 4th Gen from 2011 running iOS6)
1. Does not compile unless I comment out line 94 from SFML/Window/JoystickManager.cpp -- item.identification = item.joystick.getIdentification();
2. Using the test code above, I get the resolution 480x320@32, but it appears to work in portrait mode. Upon rotating to landscape, the drawing looks even more funny. It does not matter if I change the application orientation int he project. Please see the enclosed screenshots.

4. Crashes when killing the application from the "task bar". Here's a stack trace.

Doesn't crash for me on my Nexus 5 using the r10 NDK. However, it seems like the app is once again trying to use the context even while it's not active (so has no context). Definitely no crash happening, though.
-
2. Crash upon pressing the "Home" button. AlexAUT and ChronicRat, how did you work around it?
Which android version do you use? 4.4? Because I remember a friend told me about the home button issue on his nexus with 4.4.

2. Crash upon pressing the "Home" button. AlexAUT and ChronicRat, how did you work around it?
I have no crash with Home, but i'm catching LostFocus and whole app is paused untill GainFocus raised. Tested on 4.2.2 and 2.3.6
-
Hmm, 2.3.x does not work now. And i'm not sure that it worked before. The same build perfectly works on several 4.x.x devices.

And i'm not sure that it worked before.
Nope, since I first tested eSFML (was a fork from Sonkun and then got pushed into the main repo):
In my experience it runs only on 4.1+ and on some 4.0.x device. Hower the native activity example runs on my Galaxy S1 (2.3.4) without problems so something in SFML destroys the compatibility to the old versions.

Main problem is to load sfml-activity. May be little loader on Java will help.
Secondary problem, for me, there is bug with activity->internal(external)DataPath, it always NULL. This bug was fixed since 3.0.
Little hack for it, but i can't test it because main problem is not solved. =)
std::string GetInternalDataPath()
{
priv::ActivityStates* states = priv::getActivity(NULL);
Lock(states->mutex);
const char* path = states->activity->internalDataPath;
if (!path)
{
JNIEnv* jni;
states->activity->vm->AttachCurrentThread(&jni, NULL);
jclass activityClass = jni->GetObjectClass(states->activity->clazz);
jmethodID getFilesDir = jni->GetMethodID(activityClass, "getFilesDir", "()Ljava/io/File;");
jobject fileObject = jni->CallObjectMethod(states->activity->clazz, getFilesDir);
jclass fileClass = jni->GetObjectClass(fileObject);
jmethodID getAbsolutePath = jni->GetMethodID(fileClass, "getAbsolutePath", "()Ljava/lang/String;");
jobject pathObject = jni->CallObjectMethod(fileObject, getAbsolutePath);
path = jni->GetStringUTFChars((jstring)pathObject, NULL);
jni->DeleteLocalRef(pathObject);
jni->DeleteLocalRef(fileClass);
jni->DeleteLocalRef(fileObject);
jni->DeleteLocalRef(activityClass);
states->activity->vm->DetachCurrentThread();
}
return path ? std::string(path) : "";
}

I just thinking, can be problem that we are using C++11? I'm using static STL, but what about libc.so?

I'm continuing experiments with IDEs. Now it's Visual Studio 2013. I can share SFML solution with "vs-android" (https://code.google.com/p/vs-android/)
Next task - debugging. =)
ps Just unpack attachment to your SFML directory. Pathes in projects are relative.
upd: There were some errors in parameters, so i'll share with this solution on demand.

There is problem with OpenAL again - crash on pressing "Home" button. Rebuilding last from openal-soft solves the problem. Hmm, it solves if openal was built on Linux, but not in Windows. =)

Looking for reason why segmentation fault on 4.0.4 and less. I tried to use std::thread and std::mutex. And found deadlock here:
EglContext::EglContext(EglContext* shared, const ContextSettings& settings, const WindowImpl* owner, unsigned int bitsPerPixel) :
m_display (EGL_NO_DISPLAY),
m_context (EGL_NO_CONTEXT),
m_surface (EGL_NO_SURFACE),
m_config (NULL)
{
#ifdef SFML_SYSTEM_ANDROID
// On Android, we must save the created context
ActivityStates* states = getActivity(NULL);
Lock lock(states->mutex);
states->context = this;
#endif
// Get the intialized EGL display
m_display = states->display; // getInitializedDisplay() - this function locks locked states->mutex
-
Why dlclose can be called in the very begining of the program? It looks like some library has been unloaded. It happens on Android < 4.0.4 only. I don't what's happening. No ideas. I have no hardware device with 4.0.3, by some reason i can't debug on emulator when program just started.
-
I don't know why but now after onPause and then returning to app called ANativeActivity_onCreate.
Something like this works for me:
if (!oldStates)
{
// Launch the main thread
std::thread* thread = new std::thread(&sf::priv::main, states);
//sf::Thread* thread = new sf::Thread(sf::priv::main, states);
// thread->launch();
// Wait for the main thread to be initialized
states->mutex.lock();
while (!states->initialized)
{
states->mutex.unlock();
sf::sleep(sf::milliseconds(20));
states->mutex.lock();
}
states->mutex.unlock();
// Share this state with the callback functions
activity->instance = states;
}
else
{
states->context = oldStates->context;
states->forwardEvent = oldStates->forwardEvent;
states->processEvent = oldStates->processEvent;
free(oldStates->savedState);
delete oldStates;
initializeMain(states);
// Share this state with the callback functions
activity->instance = states;
}
PS Anybody works with Android SFML? :(

Hi here,
I've been very busy lately and I couldn't work work on the Android port. I'm back now and I had time this week to make progress on your issues. Will reply shortly :)

Hello,
I am trying to compile an SFML example on Android.
I use the android-ndk-r10b, the adt-bundle-windows-x86_64-20140702 with Qt 5.3.1 and I'm on Windows 7 Pro 64 bits.
I had no problems to compile SFML for Android.
However, when I want to run the SFML example on an AVD, I had a segfault :

P. S. : Why can't I create sf::String(const char*) ? I have read the cause is the std::locale, but how resolve it ?
If I forgot something, I can specify.
Best regards,
jd6.
P. S. 2 : I'm not english, so perhaps I made some mistakes. Do not hesitate to report me these. Thanks !
-
While Android doesn't support locales, you should still be able to use std::string just fine. In fact, your locale is simply locked to "C".
A bigger problem might be your use of a wide character string. The Android NDK's support for wide character strings is still very minimal and most stuff is simply broken or not implemented.
You could try debugging your app, just use the "ndk-gdb-py" script/batch file found in the NDK dir.
What happens if you don't use the QT stuff at all? Is there any reason to include it?
-
Thanks ! :)
When I replace my old sf::String(wchar_t*) by sf::String(std::string("test")), I had an error : undefined reference to 'sf::String::String(std::string const&, std::locale const&)'. Why had I this error ? I tried sf::String(std::string("test"), std::locale("C")), but it doesn't work. How can I resolve it ?
How can I do not use wide character string ? Thanks in advance for your response.
I use Qt to get its classes which can be useful. Likewise Qt supports Android easily. But I think I will try without Qt stuff. And I will try debugging like you say ("ndk-gdb-py") when this problems will be resolved.
In any case, thanks for your response !
-
Just use "sf::String test("some text");" for now.
-
Thanks for your response ! :)
Unfortunately, it doesn't work :
main.obj:main.cpp:function main: error: undefined reference to 'sf::String::String(char const*, std::locale const&)'
collect2.exe: error: ld returned 1 exit status
The new code :
#include <iostream>
#include <string>
#include <cstdlib>
#include <cwchar>
using namespace std;
#include <SFML/Graphics.hpp>
#include <SFML/System/String.hpp>
#include <QCoreApplication>
int main(int argc, char* argv[])
{
sf::String test("some text");
sf::RenderWindow window(sf::VideoMode(200, 200), test);
sf::CircleShape shape(100.f);
shape.setFillColor(sf::Color::Green);
while (window.isOpen())
{
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed)
window.close();
}
window.clear();
window.draw(shape);
window.display();
}
return 0;
}
-
This is really weird. What happens without the QT header?
-
Without "#include <QCoreApplication>", I had the same error.
-
Hm, I wanted to write that I have all ok with sf::String, but I've found that I have no any code with using of sf::String(const char*) directly. It's because I'm using LanguageManager where all text is in external lang files and sf::String returned by function that converts UTF8 source text to std::string.
-
Thanks for your answer ! :)
So I will continue to use wchar_t*.
Now, I will try debugging without Qt. I keep you informed.
-
I tested without Qt. I used Eclipse and ndk-build. But, I always had the segfault :

Android SFML does not need any Java code. All inclusive! =)
-
Thanks for your answer ! :)
I tested the example like Sonkun explained, and the program works ! I will try now to develop my own game, and I hope that I will have no bugs.
-
I hope that I will have no bugs.
Use IDDQD for it. =)
-
By the way, NDK r10c released.
Made the following changes to download structure:
Each package now contains both the 32- and the 64-bit headers, libraries, and tools for its respective platform.
STL libraries with debugging info no longer need be downloaded separately.
Changed everything previously called Android-L to the official release designation: android-21.
-
Got something new for you to test. :)
CMake 3.1.0 (atm available as RC2) is now able to create project files compatible with Nvidia's Nsight Tegra extension for Visual Studio.
The changes from this commit (https://github.com/MarioLiebisch/SFML/commit/67a86849c93d9c7d76c50e2f19b5f810442c4b7d) make it possible to use the Android toolchain file and create a project for Visual Studio without further changes.
Unfortunately sfml-graphics won't build for me and I just can't find the problem (I'm obviously missing some minor detail). Linking fails due to references from sfml-window and sfml-system missing, which can't be true (since the other libraries depending on sfml-system link just fine). Order of modules/libraries on command line etc. are fine. Feel free to try it and tell me what you think is going wrong. :)

http://blogs.msdn.com/b/visualstudioalm/archive/2014/11/12/debugging-c-code-on-android-with-visual-studio-2015.aspx
Anybody tested with VS2015 preview? I think it is epic win for MS. But I've not tested yet.
-
Same can be done with Nvidia's Tegra Nsight already. :)
I don't even have to use the toolchain file to build (some minor adjustments required). Yet there's still that annoying bug that keeps sfml-graphics from linking.
Debugging SFML apps on Android/connected devices works like a charm though. :)
-
I didn't knew about this thing. :o
-
Generated projects wants "-std=c++11" to compile
and I corrected "-lEGL -lGLESv1_CM" to "EGL;GLESv1_CM" manually in vcproj files (VS2013CE) - my fault, bad patching. And now I have the same bug with linkage of sfml-graphics.
And there is need for variable to place libs in subdirectory by architecture.
-
Hi there.
I'm currently trying to get a simple sample app to work in iOS Simulator. After the hell having to compile FreeType-lib and LibJPEG (I have no idea which versions have been compiled and committed to the repository, but the last trunk versions of these have various incompatible parts of source code), I have now have a running app based on the MacOS Sample Code for the main loop. However. The screen stays black. Trying to change the glClearColor does nothing, it stays black. Further the "[m_context presentRenderbuffer:GL_RENDERBUFFER_OES]" call inside the "EAglContext::display()"-method takes about one second. No vsynch, no frametime specified.
Any ideas?
Edit: I forgot to include SFML/Main.hpp. Then I had to remove the Storyboard-reference from Info.plist, but now my main() doesn't get called anymore at all.
Edit2: There had been no way to get CLang convinced to call my "main" (actually internally the "sfmlMain"). Seems to be a linker-issue. Currently I performed a hack I'd like to remove: I have my own correct "main", that one calls the MainiOS.mm-main (I renamed it), then it starts the Application-Delegate and calls back my sfmlMain. I have removed the function-definitions in SFMain.mm for that to work (even though they were weak). Like I said, I'd like to rather have my SFML not patched this way, but I didn't get it to work otherwise.
-
Yet there's still that annoying bug that keeps sfml-graphics from linking.
I remember that I had the same problem with "vs-android". Then I removed "soname" setting and the problem was solved. But with Nsight I can't see the way to remove "soname" from command line.
But with "vs-android" there were troubles with all libraries...
-
I remember that I had the same problem with "vs-android". Then I removed "soname" setting and the problem was solved.
Hah! That did the trick. Just add -Wl,--soname= to the linker's "Command Line". Haven't tested it yet though (those libs are significantly bigger than stuff compiled with make.
-
Yes, it works! =) But linker must be not "gold" - I tried it all. =)
May be this can help too - http://www.cmake.org/cmake/help/v2.8.12/cmake.html#prop_tgt:NO_SONAME
And in .vcproj I've found "<SoName>libsfml-window.so</SoName>" - removing of this does nothing without "-Wl,--soname="
-
Mario, I like NSight, thank you. I was close to buy VisualGDB. You saved my money. =)
-
Is there any legal way to avoid "move" event after finger down?
-
Why would you want to prevent that? TouchBegan, Moved and Ended are basic concepts for any touch sensitive API. If you want to ignore that event, you'll have to create your own logic to stop handling it in certain circumstances.
-
I don't need "move" event when I just touched the screen. I don't moved anything. I made a hack to avoid it but it is not normal behavior anyway.
-
You get a move instantly after a TouchBegan? Or you don't get a TouchBegan at all? Both sounds odd though indeed. I'd believe though that SFML isn't creating events which don't came from the OS.
-
You get a move instantly after a TouchBegan?
Yes. And it is not SFML's bug.
-
By the way, I tried static build for SFML, except sfml-activity.so, and size of APK file 20Mb instead of 28Mb now.
And I don't have ideas how to avoid use of sfml-activity.so... OS tries to load "openal" and "sndfile" and can't find them.
-
That's the tricky part discussed a few pages earlier.
Similar to your standard main() you'll need an entry point for your activity, which is in sfml-activity. Due to the way the linker works by default, this entry point won't be importet/added to the resulting binary.
You can avoid that, but you'd have to include the code of sfml-activity in your own shared library.
Not sure about your problem wrt openal/libsndfile, although I haven't tried static linking so far.
-
"sfml-activity.so" has no dependencies of openal and sndfile so there are no problem to start from here and to load deps manually. But without "sfml-activity" the main object is my app:
<meta-data android:name="android.app.lib_name" android:value="croger_d" />
And my app has dependencies from two libs - openal and sndfile. When my app succefully found then OS tries to load it. And can't load dependency of openal and sndfile - not found. But "libopenal.so" and "libsndfile.so" are in APK and registered in META-INF.
-
Ah, but not really sure what's causing this. Although something interesting to try/test.
-
And the most intresting, now app runs on 4.0.3 emulator and almost runs on 2.3.3 (but can't create RenderTexture). With shared SFML libs app succesfully worked only on 4.2 real device.
-
How about to make this function returning int
int InputImpl::setVirtualKeyboardVisible(bool visible)
where int is height of VK in pixels?
-
Didn't try, but shouldn't you get a resize event? Not sure right now.
-
Nope, no resize event now. And latin chars only sent by sf::Event::TextEntered. =(
I'm getting AKEYCODE_UNKNOWN when trying to use russian.
case AKEY_EVENT_ACTION_MULTIPLE:
// Since complex inputs don't get separate key down/up events
// both have to be faked at once
event.type = Event::KeyPressed;
forwardEvent(event);
event.type = Event::KeyReleased;
forwardEvent(event);
// This requires some special treatment, since this might represent
// a repetition of key presses or a complete sequence
if (key == AKEYCODE_UNKNOWN)
{
// This is a unique sequence, which is not yet exposed in the NDK
// http://code.google.com/p/android/issues/detail?id=33998
}
-
As far as I know the NDK doesn't properly support multibyte character codes, won't change soon (unless something changes in the NDK).
-
sf::RenderTexture - clear({0, 0, 0, 0}); - does not work on Android 4.2. It can't fill with transparent colour, black colour works well.
Well, alpha 128 works too.
I don't know what it was, but it works now. :o

We've just updated Nsight Tegra from version 2.0.0.14317 to version 2.0.0.15033 with the following changes:
Fixed the soname of the built shared libraries (it was always empty)
Fixed hangs/timeout issues some of the users were experiencing during the debug launch process
Fixed inability to merge normal archives into a thin archive
Fixed gdbserver uploading/choosing mechanism to continue if one of the steps throws an exception
This release is not a part of TADP3.0r4 and should be downloaded and installed manually: https://developer.nvidia.com/gameworksdownload#?dn=nsight-tegra-visual-studio-edition-2-0-refresh
https://devtalk.nvidia.com/default/topic/612548/nsight-tegra-visual-studio-edition/nsight-tegra-fixes-since-release-check-here-to-see-if-your-bug-has-been-fixed-/

I need some help please: I receive when I run in a virtual device( API 15) the example provided:
627-627/com.example.sfml A/libc﹕ Fatal signal 11 (SIGSEGV) at 0xdeadd00d (code=1)
I'm using ndk-r10d.
-
If this is the thing what I think, so I solved this problem by compiling against static SFML. And application can work with API-9 too.
-
I use API 15 because is the same with my phone.
I have built with -DBUILD_SHARED_LIBS=0, but same error. I think I still need to edit some files in the example, but don't know where.

Aaaargh! :D
All that time I wasted trying to determine why linking of sfml-graphics would always fail when not using the extra toolchain file!
But now...
Good news, everyone! It's now possible to compile SFML for Android utilizing Visual Studio and Nvidia's Nsight Tegra VS Edition alone. It's no longer necessary to bother using the toolchain file for CMake if you've got Windows. :)
Now we just need some more testing (everyone invited having the proper system for this), since I'd like to merge those changes as soon as possible (for further improvements not directly related, like being able to pick a STL implementation):
- Checkout the feature/andfixes (https://github.com/SFML/SFML/tree/feature/andfixes) branch from the official repository.
- Install the latest version of Nvidia's Nsight Tegra Visual Studio Edition (https://developer.nvidia.com/gameworksdownload#?dn=nsight-tegra-visual-studio-edition-2-0-refresh).
- Create a new build directory and use the following CMake command line to create your project files: cmake -G "Visual Studio 12 2013" -DCMAKE_SYSTEM_NAME=Android -DANDROID_NATIVE_API_LEVEL=9 -DANDROID_ABI=armeabi path/to/source Of course you can adjust the variables as you need.
- This shouldn't generate any warnings or errors. If it does, post about them.
- Open the generated solution, build, install and test it.
Next Steps
(Open for suggestions)
- Allow picking some specific STL implementation.
- Add defaults for Android (i.e. API level).
-
I use API 15 because is the same with my phone.
I have built with -DBUILD_SHARED_LIBS=0, but same error. I think I still need to edit some files in the example, but don't know where.
You can't just build static Android SFML. I made some changes in code and I used Tegra-Android to build it. https://bitbucket.org/SteelRat/gipe/src/711aa6630f0db3f277c4484ffc15f99051d368a3/deps/sfml/?at=default = there you can see what I done.
-
I've been trying for the past few days to access a Java class from Android SFML. So far, I've tried to get access to JavaVM and/or JNIEnv, but for some reason it cannot find my Java class (It's in the apk and such).
My goal is to use SFML for graphics, but I have an Android library that I'm using which requires the use of Java.
Anyone have any pointers for how/where to call a Method from a Java class using SFML for Android? Or is it not possible at this point?
Thanks in advance for any help.
-
Wouldn't it typically be the other way round? You write a Java-App and access some C++ native code via JNI from Java?
-
Yeah, I was thinking that too, but if going from a Java standpoint, I don't know how to get SFML running on a Java-based Activity. I've tried a few things, but no luck. So at this point I'm assuming that for SFML, you'd have to call Java from the C/C++ code.
-
Yep, it's not really made for that purpose (so far).
You can look into the Android specific code of SFML (src/SFML/window/Android) to see how you can call Java stuff from C++, although it's quite tricky and anything but clean.
I thought about creating an easier wrapper class to call Java stuff as an extension (not core SFML), but lack of time and too many other things to work on first.
-

I think Qt could be a good source for inspiration. They have solutions for both ways:
- they have a QtAndroidExtra module (http://doc.qt.io/qt-5/qtandroidextras-index.html) for Android, with a few useful wrappers like QAndroidJniObject (http://doc.qt.io/qt-5/qandroidjniobject.html)
- you can have a "Android sources" directory with all the native Java stuff that you need: a custom manifest, resources, Java source code, etc. (see "how to deploy on Android (http://doc.qt.io/qt-5/deployment-android.html)"); this directory will be put into your final apk (and stuff that you don't define yourself will of course be generated automatically)

Hmmm, I see.
I've tried a few things with the aim of executing some Java code, but so far it seems that either my Java .Class files aren't being loaded, or the Java VM handle/pointer/thing I get just doesn't know where they are. Any ideas? I've tried accessing the VM before the main function is called in MainAndroid.cpp [in void* main(ActivityStates* states)].
The .class files are in the .apk... I just don't know at what point they are loaded (or if they are loaded), and where that is in relation to the SFML entry point.
-
No idea, haven't really dabbled into that so far. What happens if you define a second (dummy) Java activity that references that code?
-
Had to make sure that in the AndroidManifest.xml, android:hasCode="true"
Once that is set, the .class files are available, and I can access them through JNI!
-
Hey guys! I finally managed to build and make SFML work on my phone(that is some really amazing stuff), but I still have one major problem - the audio ain't working. Loading from file returns message that the file isn't supported, and loading from stream(example from page) just... does nothing. Well it works perfectly on my PC after dropping libsndfile-1.dll and openal32.dll into assets, but how to make it work on Android?
-
I think there are still a few unmerged bugfixes for audio stuff (not 100% sure right now), but basic handling should work - using the default functions you're restricted to assets inside the APK though.
Have you tried the SFML example for Android?
-
Audio on mobile devices is not included in the 2.2 download version. It is available in the master-version from github though. Although I'm not entirely sure about this on Android, on iOS however libsndfile was not allowed to be linked statically which resulted in the iOS version to be without any sound support at all.
-
Well, I built everything with the official instructions, from the newest master version and used the android example as a base. There was sound file and music with that example, none of them worked.
-
Any more details you can provide? Like your NDK revision, your target NDK/API level, target SDK level, etc.?
-
Thanks for Your responses. I'm using newest NDK avaible(r10d), 4.4.2(19) as a target, 9 as min(I guess that's standard config from example), nothing fancy. Also - sometimes the SFML window just don't get open - app stucks on the default theme background; sometimes it even crashes whole android. Any ideas?
-
Not right now. What Android version does it crash on? Any logcat output you can share?
-
Yeah, well it shows some "Failed to activate window's context" and "called unimplemented OpenGL ES API"(even when it works just fine). It usually crashes when i close my app and try to run it again in short period of time. And sound is still not working ;p
I'm using my device(Samsung Galaxy SIII with Android 4.1.2(16) directly by usb cable. Even tried downgrading target level to 16, but I guess it doesn't even make any sense to do so.
-
Which "unimplemented OpenGL ES API"? Any more details? The context errors/warnings are fine.
-
How can I check it? It doesn't say in the LogCat.
BTW I'm getting "Fatal signal 11 (SIGSEGV) at 0x00000028 (code=1), thread 26308" when I close the app.
-
Those might all be related in some way, we're still talking about SFML's example app?
-
Yep, nothing changed over here.
-
Now I'm getting beside the sigsegv these errors:

-
Haven't had any time to build or test the library lately, hopefully will be able to do so later this week (along with finally trying to fix some of the open issues). Which version were you using? Latest master? If not (or even if so), which revision/commit?
-
Lastest master, 80214d1cb916ae5f49c63ade4c167369faab9b9e .

I'm also getting this error trying to run the example on a virtual android device.
05-11 22:12:43.950: E/libEGL(863): called unimplemented OpenGL ES API
I'm running archlinux and have the 32-bit and the regular libEGL library. The app doesn't crash and it seems to work fine except that the image is a white square.
-
So just tried on my Nexus 5. Except being unable to load the canary.wav file, the app runs fine. Maybe it has to do with Android 4.x...
Could you try applying the following commit, then recompiling everything and trying again?
https://github.com/fizixx/SFML/commit/39e8d5fd611c91674e0bf2219153676e2f0dc730
This might fix some of the sigsegs, but probably won't change anything regarding the EGL error.
-
Identified the sound loading issue, which might also cause the sigsegv... still not sure how that got in there.
Edit/Update:
Please test this commit:

I have searched around a bit and can't find anything, so I'll ask here. I'm not sure how to build an app with the android version, I downloaded and built it and everything, but I'm not sure what project type to build (I'm using VS13 with the NVIDIA Tegra thing) do I build an android project or a C++ project? Also, how do I link the .so files, the same as usual? I tried on an android project but got somewhere around 107 errors, the top ones said that the .so files (libsfml-activity.so etc.) didn't exist.
Is there a project setup tutorial around here anywhere? Thanks.
-
After you compiled SFML for Android( here (https://github.com/SFML/SFML/wiki/Tutorial%3A-Building-SFML-for-Android)) just go in the folder of the sfml example and run ndk-build and then open normally the project in Eclipse or Android Studio.
-
Project setup is very easy, you just select in eclipse-adt "Android porject with exisiting source", then navigate to the SFML directory, examples, android. Then you can check the checkbox beneath something like "copy project into workspace" so you won't modify the SFML-android example for future projects.
(I'm not quite sure, Kroniax-android is a long time ago ;), but I think you have to add native support to your project, rightclick on the project->android tools->Add Native support.
(I haven't seen the respone from AlexxanderX, before I posted this ::) )

Any news on the other bug I was having?
05-11 22:12:43.950: E/libEGL(863): called unimplemented OpenGL ES API
-
Not yet, some lack of time and still have to find out whether I'm actually able to reproduce it. Are there any other logcat lines nearby that might be related?
-
About WindowImplAndroid::getUnicode.
There new Java object is created and I think it can cause Java stackoverflow without delete of local reference.
Add lJNIEnv->DeleteLocalRef(ObjectKeyEvent); before detach of Java thread.
You have to delete local refs manually for all created Java objects, even strings.
-
Yeah, there are quite a few never freed Java objects anyway. Haven't read too deep into it, but I'm aware that those are most likely not freed right now.

I just started to work hard with JNI at my job two monthes ago. =) Btw, it is useful to create RAII class to attach Java thread (so we need JavaVM only, pointer to JNIEnv we'll receive after attaching to the thread). And check for exceptions after retreiving of method ids or classes.
I use macros for it:
#define JAVA_EXCEPTION_CHECK_AND_DO(env, doNext)\
if (env->ExceptionCheck())\
{\
jthrowable throwable = env->ExceptionOccurred();\
if (throwable != NULL)\
{\
Java::LogException(env, throwable);\
doNext;\
}\
}
This allow us to not to crash each time if something goes wrong with Java.
Class for attach to Java thread:
namespace Java
{
class Thread
{
public:
explicit Thread();
explicit Thread(JavaVM* jvm, JNIEnv*& env);
~Thread();
void Attach(JavaVM* jvm, JNIEnv*& env);
void Detach();
bool IsAttached() const { return m_Attached; }
private:
bool m_Attached;
JavaVM* m_JavaVM;
};
} // namespace Java
Implementation:
namespace Java
{
Thread::Thread():
m_Attached(false),
m_JavaVM(NULL)
{
}
Thread::Thread(JavaVM* jvm, JNIEnv*& env):
m_Attached(false),
m_JavaVM(NULL)
{
Attach(jvm, env);
}
void Thread::Attach(JavaVM* jvm, JNIEnv*& env)
{
assert(jvm);
assert(!m_Attached && "Must be detached before call this function!");
m_JavaVM = jvm;
int status = m_JavaVM->GetEnv((void **)&env, JNI_VERSION_1_6);
if (status == JNI_EDETACHED)
{
jint res = m_JavaVM->AttachCurrentThread(&env, NULL);
m_Attached = res == JNI_OK;
}
}
Thread::~Thread()
{
Detach();
}
void Thread::Detach()
{
if (m_Attached)
{
m_Attached = false;
jint res = m_JavaVM->DetachCurrentThread();
assert(res == 0);
}
}
} // namespace Java
Using:
JNIEnv* env = NULL;
Java::Thread attach(m_JavaVM, env);
env->FindClass(....
And we don't bother where to exit from the function.
And another one note: use variables to hold method ids or java classes. It will improve performance greatly.

And you have to call Init function each time "ANativeActivity_onCreate" called.
-
About this part of code:
// This requires some special treatment, since this might represent
// a repetition of key presses or a complete sequence
if (key == AKEYCODE_UNKNOWN)
{
// This is a unique sequence, which is not yet exposed in the NDK
// http://code.google.com/p/android/issues/detail?id=33998
}
In this case you have to return value as Unhandled event. This will allow to catch this event in Java and use "KeyEvent.getCharacters" method. Now your "handled" variable is always set to 1, and user can't catch this event in "dispatchEvent" method.
-
Btw, object returned by (JNIEnv) GetObjectClass requires to delete local ref to it after use. Or you can get this error: "E dalvikvm: JNI ERROR (app bug): local reference table overflow (max=512)"
I just ran stress-test for previously posted VirtualKeyboard to initialize it per frame. So, we need to delete local reference to EVERY jobject (jclass, jstring, jarray) - CallObjectMethod, GetObjectClass, FindClass... for all of them.
I updated post with VirtualKeyboard class. There are fixed leaks of local refs. Pay attention to other way to get unicode value. I think it is better (no proofs =)).
-
Yeah, those references... wanted to have a look at them for a long time now.
I've created a new commit/branch here: https://github.com/SFML/SFML/commit/40248b65c309c5b95e57dd4c21f74668be89b4da
Would be great if you could have a look, since I'm not really familiar with the different reference types (local vs. global vs. weak global).
This also fixes the unhandled input event.
-
Well, local reference will be broken as only you detach from the thread, but it is required to be deleted before detach anyway.
Weak global is good to transfer object through several functions where Java thread attached/dettached several times. I did stress-test for it, and most weak references were active whole app runtime, but one of them was broken after 1000-1500 cycles. So, it is bad to hold them whole app lifecycle, nobody knows when it will become broken.
And global reference is reliable and good to hold never changing objects. So, it is better to use in previously posted VirtualKeyboard class, for example.
I hadn't notice change of JavaVM pointer in "ANativeActivity_onCreate", I don't know how constant this value is. Sure, it is good idea to reinit all Java RAII objects in the case if activity->vm will be changed.
About code - looks like you go in the right way. =)
-
Don't think the JVM ever changes while the app is running (would be odd IMO), so I'm still toying with the idea of just having one static "JavaEnvironment" class or something like that handling all the references, lifetime, etc.
-
Is it possible to use more than one Java VM in the app? I don't know why. =) Well, I think that static "JavaEnvironment" is good enough if there is only one JVM.
-
I've built SFML for Android and I get a "Failed to activate window's context" error when I launch the "android" example inside my Nexus 7 2013. Do you have an idea about what's wrong ?
-
That "error" is completely fine. Right now you should get it a few times till your app is actually shown on screen. If your app doesn't show up, gets stuck or crashes, the issue is mostl ikely some other line in your logcat output.
-
Thanks for your answer. Nothing shows on the screen (except the app title and the default background color). But I see an error coming from the "canary.wav". So I removed the lines playing the sound and it works perfectly.
-
It's a bug with sound loading in 2.3, see a few pages ago. There's a branch and pull request on GitHub if you'd like to try a fix.
-
Btw, to get unicode (non-english, while it's impossible in pure NDK) value use Java:
public class AppActivity
extends NativeActivity
{ // transfer unicode value to C++ public static native void UnicodeValueCPP
(int value
); // we are using this to catch non-ascii chars (yes, it is impossible in NDK) @Override
public boolean dispatchKeyEvent
(KeyEvent event
) { String chars
= event.
getCharacters(); if (chars
!= null && !chars.
isEmpty()) { UnicodeValueCPP
(chars.
codePointAt(0)); } return super.
dispatchKeyEvent(event
); }}; You just need to change in manifest file android.app.NativeActivity to .AppActivity.
-
Yeah, well, only problem, there's no Java code in SFML (it's a 100% native activity). Not sure this event can somehow be overridden.
-
But SFML has NativeActivty. This method overrides it. Be sure, I tested it before posting here. =) You have to create subfolder 'src/com/company/application', AppActivity.java there - and it will work. Especially it can be easily done with nVidia AndroidWorks.
upd: Well, I'm not 100% sure about String method 'codeAtPoint', but the string value of getCharacters is absolutly correct - it contains unicode char of pressed key.
-
Okay, so you can still override those despite explicitly using the native activity? That's interesting, although an ugly workaround. Maybe it's possible to inject the code at runtime. :)
-
Maybe it's possible to inject the code at runtime. :)
I think it's possible.

I'm interested in learning how to set up the SFML for Android build. I'm using the tutorial from the wiki and I ran into an error while running cmake:

I checked and double checked my PATH variables to see that they pointed to the Android SDK directories and NDK. My directories are set up like /example/SFML/ and then /example/SFML-build-mobile and I am using CMake-GUI.
I have been able to run SDL's sample android project so I 'm sure ndk-build is working at least for that project.
I'm using CMake 2.8.12.2, Linux Mint 17.2, and I'm building off the SFML master branch (26fc872844) if that helps any.
-- An idea just popped into my head, do I need a specific Android SDK API level? I only have 18 and 21 or 22 right now.
-
CMake won't check your PATH environment variable for cross-compiling (bad things might happen!). Instead you have to set ANDROID_NDK to point there (or pass it as a CMake variable).
-
Well, I got it all figured it out and I got the example program running on my phone using Android Studio (My phone is a LGL41C with Android version 4.4.2). I had to create the project manually in Android Studio which was not hard at all since I had played around with the NDK already. I couldn't import the SFML android example though because Gradle couldn't be configured from the project, so I just copied everything over by hand. I also added the JNI stuff to my app build.gradle file so it looks like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.example.sfml_helloandroid"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
sourceSets.main {
jni.srcDirs = []
jniLibs.srcDir 'src/main/libs'
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.1'
}
I followed information from this Stack Overflow Q (http://stackoverflow.com/questions/16667903/android-studio-gradle-and-ndk)
I couldn't hear any sound from the example but I was able to move the icon around with my hand. I hope to play around with it more later on.
I am getting spammed about an error: "Failed to activate window's context" which I think I have seen mentioned here already several times and not to worry about it.
Last, I have a quick CMake question. Is there some way I can use CMake-GUI to build the libraries (armeabi, mips, etc)? I tried to by adding the variables that I normally would use from command line and it couldn't seem to figure out I wanted Android and not desktop SFML, so I'm probably not adding the right variables. I had no issues using the command line CMake from the example (https://github.com/SFML/SFML/wiki/Tutorial%3A-Building-SFML-for-Android) after following Mario's suggestion above.
-
I'm usually using a small batch file to build and install all architectures at once, I'm sure you can use that to figure out the correct parameters:
@echo off
set ANDROID_NDK=E:/Android/NDK
set ANDROID_SDK=E:/Android
for /D %%D in (*.) do (cd %%D && (mingw32-make install || (cmake -G "MinGW Makefiles" -DCMAKE_TOOLCHAIN_FILE=../../../cmake/toolchains/android.toolchain.cmake -DANDROID_ABI=%%D -DANDROID_API_MIN=9 -DCMAKE_BUILD_TYPE=Release -DANDROID_STL=c++_shared ../../.. && mingw32-make install)) && cd ..)
This obviously only works for Windows, but you can do similar things on other systems.
What this does is compiling all architectures identified by the name of the sub folders right next to this script. E.g. to build "armeabi" and "x86" I just create two folders with those names and run it.
-
Excellent work, until now everything works fine. Only i don't know how to hide navigation bar (this on bottom) on tablet devices. Anyone help?
-
It should auto-hide on its own, if you request a window with sf::Style::Fullscreen, which should activate immersive mode, if available (Android 4.x and higher).
-
I'm testing it on android 4.4.2. On newer (5.x) or older (2.3.3) with physical button it's working.
Adding sf::Style::Fullscreen doing nothing.
-
I read that SFML works on Android & Ios from v2.2
This is the only thread I could find on the subject.
Is android & ios support support still in the early experimental stages, or everything works?
Why are there no ready-made compiled libs to download like for Windows?
Thanks
-
Yes, support for mobile platforms is still experimental.

thanks for the info.
is there any resources or information yet for this experimental support, especially for ios?

Hi all,
first of all i want to say sorry for my bad english, i'm italian and i always try to do my best...
i'm Gekko and i just registered on SFML forum after my friend BJAdams suggested to me.
Like BJ i come from another engine that i used to publish all my apps (120 at the moment, all on Apple devices).
Many of them are top sellers and i will always be thankful to them as that engine changed my life.
But now the things are changing, i reached a bigger level and i need a better 2D engine that follow what a "successful" developer need.
I don't want to talk of that engine, but i'm here to give my knowledge on iOS/MAC/tvOS/Watch for free.
I understand you don't know me, but give me a possibility.
I have all the devices from Apple, including the tvOS Developer Kit, as they always take me in consideration for the earning i carry them.
My kind of coding is C++ mixed with OBJC and my friend BJ said that SFML is C++ but need some support on Apple side.
Now i will give a look to the SFML test for iOS to get an idea and wait for some reply here.
I will try to have a working test and i will post something when done, while wait for an Admin reply :D
I hope i will be usefull to the community...
So... here i am :D
-
BJ said that SFML is C++ but need some support on Apple side.
Yep, that's true. Mainly for testing on OS X (bug report and so on). The iOS port was not, as far as I know, used a lot so if you have feedback on that one it's highly welcome.
You can find out how we work here and how to contribute (http://www.sfml-dev.org/development.php). ;)
-
The exposed Native Activity handle is now available on GitHub in branch feature/android-handles (https://github.com/SFML/SFML/tree/feature/android-handles). Keep in mind that this is still unfinished, so might be buggy, and the interface is subject to change. The Android example is updated and triggers vibration, but that code isn't finished yet. Let me know in case there are any issues.
-
xGEKKOx: Your help is greatly appreciated. :)

SFML works for iOS fluidly, there's no need for any apple support and you can mix your SFML with Obj-C without a problem.
-
@BlueCobold what is the "true" status of SFML on iOS right now?
Does most of the SFML commandset work or are there problems?
Does it work on iOS9?
I would really love to get onboard SFML as I like how it works, but I need stable iOS functionality
-
The iOS port is fully functional, everything is implemented. But it lacks testing and feedback, so you can expect more or less serious bugs. I have no idea if it works with iOS9, you should just try and tell us ;)
-
so no one has been using iOS SFML since it was first made available?
its a real pity since iOS is one of the major platforms.
How about the Android port? Has it been tested and is in a stable status?
-
I am using SFML on iOS for Rickety Racquet and can't complain so far. I currently do not have any issues, no matter if using iOS 7, 8 or 9. I'm still thinking to make a PR to be able to handle applicationWillResignActive and applicationDidEnterBackground on the user-side of the application, as it often requires the app to persist some kind of state.
Android looks pretty stable too, currently preparing to build/port it to Android.
-
@BlueCobold much thanks for the good news
I think that SFML iOS should be publicized more. More people will get onboard SFML if they knew that the iOS port was usable to make games
-
I know it has been explained time and time again (Even at my request), but if there was step by step instructions on how to configure iOS/Android projects, I would be more than happy to provide testing and feedback. I'm stupid with iOS/Android setup because its not as straight forward for me as normal CMake -> VSProject -> Compile/run.
-
if there was step by step instructions on how to configure iOS/Android projects
What's the problem with the instructions at http://en.sfml-dev.org/forums/index.php?topic=13716.msg96044#msg96044 ?
-

Give it some time, that might be the ultimate goal, considering how (at least) Visual Studio 2015 integrates mobile platforms now. :)
-
as Gambit said, it would help people who just came across SFML if there were some kind of downloads or instructions on the main page, like there is for Windows
-
Yes, I guess it would be a good idea to check whether the mobile ports can be officially released, and if not, list all the blocking tasks on the tracker -- and find someone to work on them (especially for iOS) :P
-
We must organise a SEARCH PARTY to find a knowledgeable ios developer to maintain the ios version

Nothing I guess. I mean if they describe a process of going from the SFML source to an iOS/Android app then they are fine. However, I'm a Windows/GUI peasant :( I dont have make installed so I cannot run the make command in the Android instructions. I understand that the mobile ports are still in development and experiemental but I dont believe I'm too far from the truth in saying that a sizable portion of SFML users are Windows/GUI users like myself so instructions for Windows and the CMake GUI (Maybe with VS as well :o?) would be incredibly handy.
On the other hand I probably just sound incredibly lazy and stupid for asking for 1:1 steps.
-
The instructions for Android are pretty straight forward. You should really install MinGW though. CMake GUI is no magic, there's just 2 buttons and 2 textfields. The tutorials show it pretty good. iOS is not much different. Run CMake(-GUI), build+install everything with Xcode, create your app and import the frameworks to it.
-
Decoupled the retrieval of the activity handle from sf::Window::getSystemHandle() to a more generic sf::getSystemHandle() which will return the process handle on other platforms (even though it's trivial).
Testing branch is available here: https://github.com/SFML/SFML/tree/feature/system-handle
-
Tested and accepted :D
-
To get some movement again into this, the branch mentioned in my previous post has been updated with an "Android only" implementation and there's now a pull request (https://github.com/SFML/SFML/pull/1005) for discussion/comments.
-
will there ever be an official android & ios working version or will it stay as wip forever?
-
There are tutorials how to build them and there are sample applications. Except an announcement, it can't really get much more official than that.
-
Hello! Quick question - is there any SF-way to get dir structure inside of apk assets? :)
If not - do You know any? I tried dirent.h, but it's not working inside of apk.
-
At least not yet. You'll have to use the Asset Manager (http://developer.android.com/reference/android/content/res/AssetManager.html). However I don't have any snippet ready and I'm not sure whether there's NDK level access or whether you'd have to use the JNI to call Java stuff.
-
Afaik there's no "native" way of getting the apk structure. The NDK doesn't offer any class or method for that. You could use a zip-lib (also provided by the NDK) to explore the archieve. Or use a Java-call.
The Asset-Manager and Asset-Dir classes in the NDK only provide access to a file you already know the path of.
I just did exactly that recently (unpack a multi-layer deep asset-folder from the APK), so I'm pretty sure that's the only way (Java or zip-lib). It's easy to find a native snippet of using the Asset Manager to unpack a known directory or file though. There's various samples.
-
Thank You both for Your answers :) I was looking at AssetManager examples before, but does even SFML give access to the required handles(JNIEnv* env, jobject clazz --- if that's even required or I did not understand the examples)?
-
Check the test branch I've mentioned on last page. It has a new function that will expose the native handle. Check the included Android example for JNI interaction (that function is still WIP though).
-
Jup, I'm using the branch Mario mentioned to grab the AssetManager and extract my files.
-
Another thing - sf::Vertex seems to be not rendering on Android. Is that a known bug?
-
Does this work on other platforms? Because I'd say a Vertex itself isn't actually drawable.
-
Sure,
window.draw(rectangle, 4, sf::Quads);
this works on windows but does not on android.
-
Android uses OpenGL ES and OpenGL ES doesn't understand quads (which will silently fail at the moment). As a workaround, use some other primitive type.
-
Thanks, that solved it :) Getting string from resources is also not possible directly through SFML right now?
-
You should be able to use SFML's InputStream for that, which I think is wrapped to the asset manager.
-
Well, no, I think You're mistaking assets with resources now :) I'm not too familiar with whole android apk structure, but as far as I understood, strings get compiled with other resources description to resources.arsc and when You're creating a "standard" android apk You simply use @string/app_name to get app_name string, depending on user's language. It could be a neat feature for SFML(if that's even possible through native functions).
-
Ah ok, I thought you'd like to read strings from a text file. Reading string resources isn't exposed and you'd have to write the code for that yourself.
-
img.saveToFile("file.png");
not working for me. In LogCat is wrote "failed to save image". I am testing it on android.
If someone have time, pleas check it, because i don't know that this is my mistake or sfml bug.
-
Maybe You don't have permissions to write to that file? Try that:
<manifest ...>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
...
</manifest>
-
While I don't remember testing it so far, these functions should – in theory – work out of the box, given you're using the correct path (to be determined using the native context). This can be tricky and suggestions to improve this on SFML side are welcome. :)
-
Wow, great to see SFML on iOS. So far I only tested/played around on simulator, but if you guys need to test something on device count on me.
-
Is there a way to get applicationDidEnterBackground notification from iOS?
-
No.
Don't hesitate to have a look at the source code ;)
https://github.com/SFML/SFML/blob/master/src/SFML/Window/iOS/SFAppDelegate.mm#L123
-
Oh well, I could put a notification on didFinishLaunchingWithOptions from SFAppDelegate just like the one for orientation changes. I get the notifications now but I don't think it will help me back in my game as I was thinking.
-
Hello again,
I was wondering if someone can help me with this problem. After successfully building the libs my app will run on iPhone 4s and 5 simulators but fails on simulators 5s and up. I get this kind of warning for every module:
ld: warning: ignoring file /Users/christian/Desktop/SFMLtest/SFMLtarget/libsfml-network-s.a, file was built for archive which is not the architecture being linked (x86_64): /Users/christian/Desktop/SFMLtest/SFMLtarget/libsfml-network-s.a
And then tons of errors of course because of undefined stuff. Probably related to "architectures/valid architectures" but I don't know much about it. Tried a few changes but the problem remained. Any suggestions?
-
You probably need to build for 64 bits. But don't ask me how to do that ;D
-
Yeah, I did a lot of combinations until one of them worked out. Curiously it is was not the 64 bit one but this:
32 bit Intel (i386) $(ARCHS_STANDARD_32_BIT)
-
Hello!
I've been trying all day to compile SFML for android and i have been following this guide:
https://github.com/SFML/SFML/wiki/Tutorial:-Building-SFML-for-Android
So far I've made it to actually building the android example by calling 'ndk-build'.
However when I do, i get a load of errors. It seems to start out well and then fails when it reaches a shared
library in main.cpp. I can't make any sense of what it's looking for that isn't there and when i should have created that object.
Here are my errors, can any of you brilliant people infer from this what i might have done wrong?
EDIT: I have circumvented this issue by changing this line in my Application.mk:
APP_STL := gnustl_shared (instead of c++shared)

Haven't tried latest NDK so far, maybe they've changed something. From first guess looks some issue with linking order.

Hi
The iOS/Android ports are finally ready for beta-testing. This happens one month after the expected date, sorry for the delay (everyone is very busy -- more than usual). Until Jonathan pushes the code to the public repository, here is what you need to know if you want to play with them.
Where?
The ports will be available in the ios_and_android branch of the repository. This way it won't bother people who are not interested, and the amount of testers (and reports) is kept under control.
How to compile the iOS port?
To compile the iOS port, you must use the Xcode generator of CMake, and define the "IOS" boolean variable (set to TRUE) before configuring for the first time. The generated projects can then be compiled for x86 (simulator) or armv6/v7 (device) by selecting the target in Xcode; no need to generate multiple builds for that. SFML is built as static libraries on iOS (this is the only option for this OS).
To use SFML in your iOS app project, do as usual: add the include path to your project settings, and drag'n'drop the libraries into your project. Since SFML is linked statically, you'll have to link all its non-default dependencies as well (extlibs/libs-ios).
Note that you'll need a registered Apple developer account in order to copy and run your app on a device; otherwise the simulator will be your only choice.
How to compile the Android port?
How to compile the OpenGL ES port for Linux?
Things to know for Android
Jonathan will explain that as soon as he is available ;)
New API
Only a few things have been added to the public API:
- The sf::Keyboard::setVirtualKeyboardVisible function
- The Touch API:
- A sf::Touch class (similar to sf::Mouse)
- sf::TouchBegan / sf::TouchMoved / sf::TouchEnded events (similar to mouse events)
General things to know
The sensors (accelerometer, gyroscope, compass, ...) are currently using the Joystick API (see the sources for more detail about the mapping). We'll soon add a sf::Sensor API that better matches the requirements.
The foreground / background events are mapped to the GainedFocus and LostFocus events.
Orientation changes are mapped to the Resize event.
sf::Shader is not available, because the implementation is based on OpenGL ES 1. Shaders are only available in OpenGL ES 2, which would require a major rewriting of the graphics part. So that won't be done in a near future.
Things to know for iOS
On iOS, the working directory is automatically set to the resources directory.
There's no audio module on iOS, I'm still waiting for libsndfile to add a license exception for iOS so that I can use it statically without breaking the terms of the license. The author said it was one of its priorities, but it was months ago and I've got no news...
The implementation should be compatible with iOS 4.0 and more.
The size of the window is ignored, the screen size is always used.
Examples are not available. It seems that CMake is not ready for that, it still requires too many hacks, and even with them, it was still pretty bad.
The ugly hack: you need to include <SFML/Main.hpp> in the file where your main function is defined. This is because SFML has to hijack it, and rename your own main to call it later.
There's no specific support for high-resolution (retina) screens, they currently produce the same output as low-res screens (this will be done later).
Important
Until everything is merged into master, please use the forum for your feedback. You can post here or open new threads. There are still many things to do, I don't want to pollute the task tracker ;)
Thanks @Laurent

Hey guys.
So, I was testing out the iOS port last night for my game City Clickers and it seems to work sufficiently enough. Adding touch in addition to mouse controls was really straightforward. Have some weird flickering at launch (the whole screen is magenta for a moment), hopefully something I can track down. I'm not sure about actually targeting iOS, just experimenting for now but it seems promising.
Two quick questions:
1) Are render textures supposed to work on iOS?
2) As I understand, shaders are not supported due to older OpenGL ES and upgrading is quite a bit of work. How much work you reckon? What are the roadblocks? Given some good pointers, could I (with no real graphics programming experience) make something work?
It's pretty much the only thing I'm really missing atm. I have a post-processing shader to get the look I want, sort of complicated to achieve without it.
I guess I can work around something somehow but that would be an awesome addition/upgrade to the library.
The exciting moment I first got everything playable:

-
Really cool seeing the porting to be quite okay. :)
I'd say it's quite a bit of work and you'll have to adjust for some changes. Doing it without thinking about backwards compatibility probably makes things a bit easier.
Personally I haven't dug into the depth of SFML's rendering, but you'd have to most likely change quite a bit regarding context management, then you'd have to change all the rendering for modern OpenGL and finally, you'll have to ditch the current shader implementation and adjust it for modern OpenGL.
The final part is, what we've been discussion not very actively in this thread (https://en.sfml-dev.org/forums/index.php?topic=20767.0) and it's the first stepping stone towards modern OpenGL.
-
Just to mention it here for everyone subbed to the thread: SFML's current master branch on GitHub should once again build and run Android properly for everyone, even if you're using the audio module and/or use the shared C++ runtime. Apps will still fail to regain a working context once you switch out of them, though.
