Android : Touching a view that's always on screen

I have a view that's always on the screen (over other apps), I wan't to receive touch events and than to pass them farther.

The code from the running Service :

    WindowManager.LayoutParams localLayoutParams = new WindowManager.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT,
            WindowManager.LayoutParams.MATCH_PARENT,
            WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
            WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,  
            PixelFormat.TRANSLUCENT);

    v.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            Toast.makeText(getApplicationContext(), "view touched", Toast.LENGTH_SHORT).show();
            return false;
        }
    });

    WindowManager localWindowManager = (WindowManager)getSystemService("window");
    localWindowManager.addView(v, localLayoutParams);

currently I don't get the touches.
