Line'em Up

its been a few months since i started working on android… ya at first it seemed a bit tricky. (well somethings still are tricky…) my second app is live now and comparing with my first app there is a definite improvement( at least i thinks so ) my game is an extended version of tic-tac-toe. Here after placing all the coins players can move the coins to align them in straight line. Well my game logic is not fail proof yet, but in my future version you can expect a more tuf AI.
Expecting all kinds of feedback. I’ll be really appreciate if anyone can point out some real bad weakness of cpu player.
