How to send dispatchTouchEvent() from service to any Underlay Activity - events

Question

WHAT I WANT TO DO?
- Basically i want to do the human touch pragmatically at specific time at specific X,Y Coordinates
- Run a service which will receive the X,Y coordinates via some interface (TCP/UDP)
- fire dispatchTouchEvent() using those coordinates and get the results as actual human finger click gives
- I mean focussed activity might be anything either it is Android Home Screen OR Any opened activity OR Anything
- The moment service invokes the dispatchTouchEvent(), It should perform the click.
- For example if opened App is calculator and X,Y coordinates of dispatchTouchEvent() points to numeric 5, It should press the 5 key
WHAT I HAVE DONE TILL NOW?
- I have started a service which receives X,Y coordinates
- On some trigger, it invokes the dispatchTouchEvent(), but it does not work. It does not click anything on the screen.
- It capture every touch event made by human finger.
WHATS THE ISSUE?
- How to issue dispatchTouchEvent() to any underlay activity
SAMPLE CODE:
i am attaching the sample code here. I have just made it simple for test purpose.
First we need to click anywhere in the screen. Its X,Y coordinates will be saved and after some time dispatchTouchEvent() will be invoked
using same coordinates.
