Nexus 9 package

Just packaged the FPS(simple) and pushed it my Nexus 9. All see is the clouds and the sticks. Used Android-21. Tried 23 and it would not compile. When I used 4.9.2 it works OK. I thought 4.10 was going to work with android 6 Marshmallow.

Anyone. Is anyone getting Android 6 to work for any android phones?
