android - Get co-ordinates touch screen in a background service

I'm just wondering to know if a can with a background service have co-ordinates of a touch screen event in all activities.
Such like that


*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;}
but without any view by default.
Thanks See Question&Answers more detail:os

No, sorry. Your activities can pass information about touch events to a service, but a service cannot directly receive touch events.
