For the purpose of developing a new game on Android, I've tried a few scene graphs & graphics libraries for a while (even tried html5) but nothing seems to be doing what I want. cocos2d remains the best solution for developing 2d games and animations and Android phones are great to run those games too!
If you are interested to help, please don't hesitate to send me a request. You can also send a donation so I can work more hours on this project or even send a mail saying 'hi'. Feel free to send me your suggestions!
Happy gaming!
