If anyone is interested I just published the source code to my Android game Space Rocks on GitHub: GitHub - ATryder/SpaceRocks: A 3D asteroids inspired game for Android.
It’s an Android Studio project that comes with all the necessary dependencies and assets. The jme3-core.jar is a custom build with some light modifications. For the most part you should be able to load this up in Android Studio and build it. I used Android Studio 2.3.3.
