app just closes right after i open it?

i been working on this mobile app android and everything was working fine then i put admob and 8 new textures in it and when i open it up it will stay open 1/10 of the times i open it, other than that i just closes, im not sure what the problem could be, i have an old version with GPGS and IAB in it and i put it back on and it still works perfectly but right when i put admob and 8 Textures 512X256 it closes 9/10 of the times i open it, thank you for your time
