it depend on your app requirement, for example:
case 1: when press back, need over your activity, so you need invoke
finish, this is defaultcase 2: in one activity, has 3 step, like a->b->c, if you in the step b or c, you press back just want to back previous step, to b or to a, so you dont need invoke
finishmethod inonBackPressedso, above just a example, you need make a better choice in your situation.
