Android Popping off the Activity Stack

Question

In our app, we have Activities A,B,C,D, and E. The user usually goes from A to E.

In Activity E we want to go back to A, and get ride of B,C,D from the stack. We don't want to recreate A from E.

How do I 'pop off' B,C,D from the stack and then return to A ?

Answer 1

If A is already running, you can use the FLAG_ACTIVITY_CLEAR_TOP flag when starting an intent to go back to A.
