We (my company) just published our first 3D game for android. It is running on 3D engine called Rajawali which is relatively new so this was kind of engine testing. Check it out on Google Playstore: https://play.google.com/store/apps/details?id=com.mabuga.gravity.android.before4
I can say that Rajawali is very nice although it still has few major bugs, but community is working actively to fix them.
Here are some screenshots...
