Android build problem

[sergioawd]

Hello everyone, I followed this tutorial (https://github.com/SFML/SFML/wiki/Tutorial:-Building-SFML-for-Android), and when I get to the point of building get this error, I searched the Internet and this forum but can not find solution. Thank you.

Code: [Select]

C:\SFML-master\examples\android>ndk-build
Android NDK: jni/Android.mk: Cannot find module with tag 'sfml' in import path 
Android NDK: Are you sure your NDK_MODULE_PATH variable is properly defined ?   
Android NDK: The following directories were searched:
Android NDK:

Edit: Windows system.

Are you using Windows or Linux?

Please, in order to help you we need you to provide the most information you can.

[Mario]

Sounds like you forgot to actually "install" SFML after building.

Check the folder <NDK>\source\sfml to see whether it actually exists.

If it doesn't something went wrong while building or installing.

In the ndk\sources not include sfml folder...

I've been watching this post by DarkRoku http://en.sfml-dev.org/forums/index.php?topic=19298, and copy the floder sfml in my sdk/sources but the error is this now

You should build SFML libraries.

On windows you will need to use: MinGW (using -G "MSYS Makefiles" for CMake).

[Mario]

That's now a problem that should be fixed in the latest version from GitHub. Check out master branch, build, install, then try again.

Ok, try it.

Download the new SFML-Master and have this error when ndk-build, and use the main.cpp from the folder SFML-master / examples / android

You shouldn't have to copy files on your own. Go to your SFML build directory (for Android) and run the following command:

Code: [Select]

cmake --build . --target install --config Release
The last few lines should tell you about copying the files to your Android NDK directory.

After that, go to "examples/android" and run the following to build the example:

Code: [Select]

android update project --target 1 --path . --name SFML-Example
ndk-build
ant debug

Thank you for your reply.

Code: [Select]

cmake --build . --target install --config ReleaseThis create in my nkd sources the sfml source, this is all ok.

I remove folder SFML in  C:\SFML-master\examples\android\jni
And show this error now:

Code: [Select]

What is the problem?

Thank you.

[Mario]

What's your NDK version? For some reason it can't find the header files.

There should be a directory <NDK root>/sources/sfml/include with SFML's header files. If it's there, there might be something off with your environment configuration.

The NDK Version is the last version r12b.
Yes the folder C:\Android\NDK\sources\sfml\include\SFML exists and exists files hpp.

And the path in my environment configuration is good is this:
- ANDROID_NDK: C:/Android/NDK
- PATH: C:\Android\NDK and try this also C:/Android/NDK

I changed the folder C:\Android\NDK\sources\sfml\lib armeabi for armeabi-v7a, and build this (I do not know if it is ok):

But not create in the folder C:\SFML-master\examples\android\bin the apk file...

And execute ant debug and show this errors:

You shouldn't copy/move/rename files. You essentially put code generated for ARM v7 into the folder where there's code for ARM v6.

But this shouldn't cause the other problem. There's obviously something wrong or broken with your SDK, if ant fails.
