Question

I want on button press to clear the activity stack , but leave not all activities. I want to leave the launcher activity in the stack (So if the back button is pressed to go to HomeScreen).

Does:

Intent launch = new Intent(context, LnewActivity.class);
launch.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

clear ALL activities, or does it leave the launcher activity in the stack? It is not clearly said in the docs.

Answer 1

Actually it does leave the launcher Activity in the stack!

Intent intent = new Intent(this, Search.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
