Playing almost everyday, but cant play for few weeks.

Why the apps keeps closing out and will not open and load the game? 

Andriod is higher than 2 or 3.

I think you probably need to check how many apps you have open, how much memory you have free etc. If your phone is full and you're using a lot of apps then certain games will struggle to load. Free up some space if required. Oh and maybe update your android OS if possible.
