Rotate device ?

[eefret]

Yeah on Device Rotation, Althought it was very random and sincerely I have read the code to look for the reason and it doesnt make sense at all, maybe you're using a custom Button widget or something...

[brucetoo]

This may be the problem of recreate your activity or fragment when rotate device,try setRetainInstance
