Android onBackPressed/onUserLeaveHint

Question

Just a bit of advice needed really. I have an Activity running with my game in it and when the user presses the Back button it will exit back to the Main Menu using the onBa

Answer 1

onUserLeaveHint() is a protected method as other lifecycle methods of the activity and if you are handling onUserLeaveHint this will take care of the following case

1. When User hits home key
2. When User hits back key
3. When User hits annunciator bar

Basically it hints about the user is trying to leave your activity. That means if you are handling onUserLeaveHint() you don’t need to handle onBackPressed() in your code.

Answer 2

Just an idea that might help you, i'm using it for my "home-made" ActionBar to determine when the user has actually arrived at the main (and last) activity before exiting. I start the Main-Activity manually and clear the whole activity stack by setting the FLAG_ACTIVITY_CLEAR_TOP flag, so if the user now hits the back button once again, the app is gonna get closed.

Intent intent = new Intent(getContext(), MainMenu.class).
setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
