Anyone knows how to completely end the Activity when going to another Activity? I put a finish() on the activity to terminate it. But when i press the Back Key of the Phone or in the Emulator, it goes back to the last Activity i open. For example:
Activity A is the menu, B is the order, C is also the order, D is the payment.
Activity A going to Activity B, Activity B to Activity C, Activity C to Activity D.
if i press the Back Key of the Phone or the Emulator When i am in the Activity D it goes back to C, B, and A. But the Correct one should be from Activity D going back to Activity A. and if i press the back Key again it will close the App.
Anyone knows how to end Activity clearly?
Thanks!
I have a different program, here’s my game menu.

When i press the back button of the Phone or emulator, it goes back to the last activity i open. if i open game menu —–> instruction —–> back to menu —–> new game —-> game level —–> easy game and i press back button it goes back to my recent open Activity.
How to fix that?
you don’t need to explicitly call the finish every time you start the next activity, just set android:noHistory=”true” to those activities that you want to remove from activity stack.
