Andriod Project Game

I would like to create a Darts-like type game for android that would allow the user to play Darts.. by flicking the screen. I know there a lot of opensource for this game. But i need this game into a re-skinable type of game. So that i can use not only darts but everthing. Will provide images and sounds. Max. 8 levels with 8 stages and with story board.. Can store top score. This application should work with the various screen sizes available for android devices and work on any device 2.1 and above.
