title: Android - finish activity and exit app
body: <p>I have an application which consists 3 activities - lets call them A, B &amp; C.
  From activity A You can get to activity B, from B to C and from C to A (By pressing the back button).</p>
  
  <p>On activity A I have an exit button (I know it`s not recomandded on android, but a lot of users are asking for it, so I decided to add it).</p>
  
  <p>Anyway the problem is that: activity B has a timer, when the timer is finished it starts an intent that starts activiy C and calls finish() on activity B.</p>
  
  <p>When the user then press back on activity C he gets to activty A - and then when he presses the exit button (this button only preforms finish()), it pops up activity B again. How can I prevent it from happen?</p>
  
  <p>Thanks!</p>
