 @Override
 public boolean onKeyDown(int keyCode, KeyEvent event)
 {
  if(keyCode == KeyEvent.KEYCODE_BACK)
  {
   onBackPressed();
   return true;
  }

  if(keyCode == KeyEvent.KEYCODE_HOME)
  {
   onHomeKeyPressed();
   return true;
  }

  return super.onKeyDown(keyCode, event);
 }

 protected void onBackPressed();
 protected void onHomeKeyPressed();
