What settings do you get when you call getSettings() on the window?

result when run in Android Studio emu.

depthBits=0x18
stencilBits=0x8
antialiasingLevel=0
majorVersion=0
minorVersion=0
attributeFlags=0x0

Graphics / Re: SFML Android - RenderTexture Alpha Problem - It gets weirder.

« on: September 28, 2017, 03:43:08 pm »

I had a friend run the .apk on his mobile - Android 7.0 (5 février 2017)
and the result is even more dumbfounding!

the RenderTextured Sprite doesn't even appear!

Graphics / Re: SFML Android - RenderTexture odd behaviour?!

« on: September 27, 2017, 09:05:49 pm »

Ok, I expected to get the same result for drawing the Sprite set with the RenderTexture
and the Shapes directly.

It seems to be specific to Android.

I tried on OSX/IOS, no problemo, see attached pic (OSX screenshot).

btw, this is the result I expected for Android (draw(Sprite(RenderTexture)) = Draw(direct))

Graphics / SFML Android - RenderTexture Problem

« on: September 27, 2017, 08:40:20 pm »

Why do I have two different visual results for

• the Shapes
• the RenderTexture dump with a Sprite

the screenshot is taken from the Android Emulator (API 26), app launched through Android Studio
using SFML 2.4.2

not the difference of blending of the top (white, alpha = 50%) square on the grey square (grey 50% alpha=100%)

• the left group is drawn using a RenderTexture applied to a Sprite
• the right group is drawn directly

min code

void App::loop()
  {
    // FULLSCREEN mode + autoRotate ON
    sf::RenderWindow window(sf::VideoMode::getFullscreenModes().front(), "Alpha-WeirdAlpha", sf::Style::Fullscreen | sf::Style::Resize);

    // simple
    sf::RectangleShape rbg(sf::Vector2f(400.f, 400.f));
    rbg.setFillColor(sf::Color(0x808080FF));
    rbg.setPosition(50.f, 50.f);
    sf::RectangleShape rfg(sf::Vector2f(200.f, 200.f));
    rfg.setFillColor(sf::Color(0xFFFFFF80));
    rfg.setPosition(25.f, 25.f);

    // create render texture
    sf::RenderTexture rt;
    rt.create(500, 500);
    rt.clear(sf::Color(0x00000000));
    rt.setSmooth(true);

    rt.draw(rbg);
    rt.draw(rfg);

    rt.display();

    sf::Sprite sprRT(rt.getTexture());

    rbg.move(500.f,0.f);
    rfg.move(500.f,0.f);

    sf::View view = window.getDefaultView();

    while (window.isOpen())
    {
      sf::Event event;

      while (window.pollEvent(event))
      {
        switch (event.type)
        {
          case sf::Event::Closed:
            window.close();
            break;
          case sf::Event::Resized: {
            view.setSize(event.size.width, event.size.height);
            view.setCenter(event.size.width / 2, event.size.height / 2);
            window.setView(view);
          } break;
          default: break;
        }
      }

      window.clear(sf::Color(0x80a0f0ff));
      window.draw(rbg);
      window.draw(rfg);
      window.draw(sprRT);
      window.display();

General / Re: SFML and Android how to get internalDataPath?

« on: September 09, 2017, 10:31:29 pm »

well... I missed it 
it was right there in front of me in SFML/System/NativeActivity.hpp

  ANativeActivity* na = sf::getNativeActivity();
  LOGI("[PATH]=[%s]", na->internalDataPath);

General / SFML and Android how to get internalDataPath?

« on: September 09, 2017, 05:25:15 pm »

Hi everyone,

Using the NDK,
I'm trying to get the Activity's internal Data Path from main(arg, argv)

 

int man(int arg, char **argv)
{
  // here I want activity->internalDataPath
  string path( /* ??? */ );
  ...  
}
 

in main(argc, argv)

I've changed MainAndroid to send it as an argument to a mainAndroid(const char* s)
but it's sort of nasty...
is there any clean way?

I've seen this post as well https://en.sfml-dev.org/forums/index.php?topic=13716.240 but it's also a bit violent.

Anybody knows a way that doesn't require modifying the SFML source code?

All right! We are getting there! Thanks Alia5!!! 

Just modified Template + HowTo (SFML + Android + OSX)
including building SFML for Android with c++_shared STL and ndk-r12b

you can find it here: https://github.com/MoVoDesign/SFML_Template

Added: use of symbolic links in HowTo, to avoid copying libs all over the place.

good one, I did, you'll find it at the top of my code

Meanwhile it hit me as I chatted with a friend about the absurdity of so many STL implementations:

STLPORT is from 2008... so NO smart pointers! 

I rebuilt SFML with GNUSTL instead

cmake -DANDROID_ABI=x86 -DCMAKE_TOOLCHAIN_FILE=$SFML/cmake/toolchains/android.toolchain.cmake -DCMAKE_FIND_FRAMEWORK="NEVER" -DANDROID_STL=gnustl_shared $SFML
 

and defined it in build.gradle (module: app) as well

defaultConfig {
  externalNativeBuild {
    cmake {
      cppFlags "-std=c++11 -fexceptions -frtti"
      arguments '-DANDROID_STL=gnustl_shared'
    }
  }
}
 

and TADA!

« on: September 04, 2017, 05:16:52 pm »

...Hello again.

Now that I've got SFML working, I realise that the android C++11 STL support is rather shoddynamely:
here is the trouble: unique_ptr

this is the minimal example I've been working on.
Can't compile this while linking with SFML.

#include <memory>
#include <SFML/System.hpp>
#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>

int main(int argc, char *argv[]) {

  std::unique_ptr<sf::RenderWindow> upW(new sf::RenderWindow(sf::VideoMode::getDesktopMode(), "OMG!!!"));
  sf::RenderWindow& window = *upW;

  sf::View view = window.getDefaultView();

  while (window.isOpen())
  {
    window.clear(sf::Color::Black);
    window.display();
  }
}

thanks. 

You actually did it maybe 30 minutes before I completed my version.
So I started sniffing around your code and checked out what you did differently.

Short of the way we link libraries and a rather shorter and nicer way of linking sfml-main in your case it was about the same thing. So here is mine, and thanks a lot for your answer!

Well Done!

I've actually just released a template + Method for SFML for Android (With Android Studio) developing on OSX!

I tried to simplify the process to the core. Give it a check.
I had problems with link_directories it seems to be rather restrictive on OSX.
so I defined each and every external lib like the google dudes do in the Hello-libs example. Works nicely.

check out https://github.com/MoVoDesign/SFML_Template

and this is what I'm going to port to Android Now!!! http://www.movo-design.com

General discussions / Android Studio 2.3.3 + SFML 2.4.2 - Hell again.

« on: August 26, 2017, 02:26:03 pm »

Hi You All,

has anyone had any success building a minimal SFML example that can actually be built and run on the emulator?

I've tried the tutorial on GitHub (here: https://github.com/SFML/SFML/wiki/Tutorial:-Building-SFML-for-Android) - with no success since those **** people at Google decided to force you to go through their ugly IDE: Android Studio.

So I've spent so far 36h on the problem and I believe that I'm getting closer: the best lead I've found so far is here in the forum and t AlexAUT's SFML-AndroidStudio-Template (here: https://github.com/AlexAUT/SFML-AndroidStudio-Template).

There's also a this basic yet rather rich article on dev.android: https://developer.android.com/studio/projects/add-native-code.html#create-sources

So I started from these places and I am painfully trying to merge two of their examples

• Native Activity - using <android_native_app_glue.h>
• Native Lists (Hello libs)[/i]

from there I hope to find a way to bring in the static and shared libs for SFML.

did I mention that Java irks me?
Any clue is welcome!

Timeline for a Windows port.
Good question. I'm presently spending most of my free time on he Android port.
I guess Windows will come after that and shouldn't be too difficult.
I must say that I haven't used Windows in 10 years... wondering if I can install it as an alt os on my mac.
so sorry... no fixed date!
thanks for your interest though!

my mistake was to do the search on Git first and to end up with 9999+ clones of the jpeg libs...
it completely eluded me that I could go to the main websites.
