title: Android app exist when home button is pressed. Clicking app icon starts app over. I want it to just unpause
body: <p>In my game, if a user hits the back button I pop up a dialog asking if they really want to quit. However, I can't do the same with the home button because there's no way to override it.</p>
  
  <p>If the user knows the task manager trick they can hold down home and switch back to the app and not lose their place.</p>
  
  <p>If they don't know the trick they'll just select the icon again which will start the application over from the main menu.</p>
  
  <p>Is there any way to override this behavior so that instead of starting at the main menu it would go back to where it was if the app is currently running?</p>
  
  <p>I know that I could save the state of everything when the app pauses and then programmatically reload everything and send them to where they were. I'd like to avoid having to do all that work if possible.</p>
