title: Android Popping off the Activity Stack
body: <p>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.</p>
  
  <p>In Activity E we want to go back to A, and get rid of B,C,D from the stack. We don't want to recreate A from E.</p>
  
  <p>How do I 'pop off' B,C,D from the stack and then return to A?</p>
