* First attempt at building android-natives.
* Use OpenJDK because native build is broken without
* Try OpenJDK 10
* Try openJDK 9
* Try openJDK11 again but "enable" the EE Module
* OpenJDK 11 has no Java EE Module anymore.
* Try to fix Android Header Generation
* Fix invalid flag error with javac by removing empty quotes
* Try to fix build of decode.
* Remove jni generated headers from the repository.
* Adjust .gitignore as those header files won't appear at that location anymore
* Fix Android Build: Fill the jme3-android-native headers during the build of jme3-android. This works because jme3-android-native already depends on jme3-android.
Due to technical reasons, the headers share the same location and thus the include directives have been adjusted slightly.
* Copy jni headers to the jni directory.
* Adjust the path slightly
* Try to silence android sdk's license print out
* Also fix openAL
* Solve task name conflict
* Really silence license now
* Tasks seem shared but Strings are not...
* Only build Android-Native
* Trying to reduce the amount of dependencies needed.
* Remove even more dependencies
* Even more removal
* Prepare Deployment
* Fix Deployment
* Cleanup: Remove feature branch from branches for travis.
* Revert a few unnecessary things
* Removed NDK Comments.
