Android - "Faking" a touch event not working

Question

I want to fake a touch event and I have got the possible answer here. However When I attempted to make it work, it didn't work.

Note that I am running the following code in the thread.

private Handler handler = new Handler(Looper.getMainLooper());

private final Runnable runnable = new Runnable() {
    @Override
    public void run() {
        View ParentView = (View)view.getRootView();
        long downTime;
        long eventTime;

        Log.v("Screen Tapper", "Start Tapping");

        Log.v("Screen Tapper", "tapTimes ----- "+1);
        downTime = eventTime = SystemClock.uptimeMillis();
        MotionEvent event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_DOWN, x-5, y-5, 0);
        ParentView.onTouchEvent(event);
        Log.v("Screen Tapper", "touchDown ----- "+x+","+y);

        handler.postDelayed(runnable, 100000);

        downTime = eventTime = SystemClock.uptimeMillis();
        MotionEvent event2 = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_UP, x-5, y-5, 0);
        ParentView.onTouchEvent(event2);
        Log.v("Screen Tapper", "touchUp ----- "+x+","+y);

        handler.postDelayed(runnable, 100000);
    }
};

And when I want to start or stop the thread I basically call

Handler.post(runnable);

or

Handler.removeCallBack(runnable);

However, This method is not working.

I tried it on multiple games and even my own application. I know this thread is running because the logging is working. However the button is just not being pressed.

Any help is appreciated

Answer 1

It is not possible to send arbitrary fake touch events to other applications, except perhaps on rooted devices. Even there, it would be through fussing with low-level Linux input stuff AFAIK, not through the Android SDK.
