public boolean onKeyDown(int keyCode, KeyEvent event)       {          if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0)          {             this.moveTaskToBack(true);             return true;          }         return super.onKeyDown(keyCode, event);     } 

This will send the activity to the background. See documentation for further reference.
