I need help....android version keeps crashing

I've just bought the game and the breaking dead for android phone, but everything I leave the game for a while or hit a bug its crashes.

It keeps going to a black screen and won't even load a screen, and the only solution I found that works so far is to clear the cache and start from the beginning everything.

Is there something I'm doing wrong? or is there another way I can clear the crash?

Thanks for the help in advance
