Android Java Libraries in UE4 Game (OUYA SDK, Google Play Game Services, etc.)

So, this is more involved than you probably want, but an early (really, don’t use it quite yet :)) version of our Google Play services integration can be found at:

https://github.com/EpicGames/UnrealEngine/commit/122667ec999c55b8369c42e25bc4b473cfa5239f

Some of the key changes related to adding a .jar are in UEDeployAndroid.cs, where we copy the Google Play services library to our Intermediates, and then run ‘android.bat update’ on it.

Other important files are AndroidJNI.h/.cpp for calls across the C++/Java boundary, and AndroidManifest.xml, where we let the Android SDK build system know that we’re integrating the Google Play services library.

There may be a simpler approach for what you’re looking to do, and if you find something that works better, please let us know.

Thanks, looking at those commits was very helpful and finally managed to communicate Java <-> C++.
But then I’m facing the problem that the manifest and Android project folder are being rewritten every time the project is built, as explained here: AndroidManifest and Java files are rewritten everytime the project is built - Mobile - Epic Developer Community Forums
