title: Get co-ordinates touch screen in a background service
body: <p>I'm just wondering to know if a can with a background service have co-ordinates of a touch screen event in all activities.<br>
  Such like that<br>
  <pre><code>
  *final TextView textView = (TextView)findViewById(R.id.textView);
  final View touchView = findViewById(R.id.touchView);
  touchView.setOnTouchListener(new View.OnTouchListener() {
      @Override
      public boolean onTouch(View v, MotionEvent event) {
                textView.setText("Touch coordinates : " +String.valueOf(event.getX()) + "x" + String.valueOf(event.getY()));
       return true;}</pre></code>
  but without any view by default.<br>
  Thanks</p>
