We fixed the Android Studio exporter on the newest tip, and successfully tested it on all platforms.
Please update to Android Studio 2.1 Beta 3 and the newest build tools, re-build the Projucer and try again. Everything should work now.
The only catch is that the clang toolchain for Android seems to be broken on OS X, you have to use gcc for now (I made it the new default setting). See this post.
