title: Force application to restart on first activity
body: <p>For an unknown reason, I can't get my application leaving properly so that when I push the home button and the app icon again, I resume where I was in the app. <em>I would like to force the application to restart on the first Activity.</em></p>
  
  <p>I suppose this has something to do with onDestroy() or maybe onPause() but I don't know what to do.</p>
