Android Popping Off The Activity Stack

In our app, we have Activities A,B,C,D, and E. The user usually goes from A to E, moving through B,C,D. In Activity E we want to go back to A, and get rid of B,C,D from the stack.

Solution 1:

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