Send touch screen event to foreground activity (only from APK)

I am trying to send touch events (clicks and motions) to the foreground application from an application with system privileges (standard upload, not rooted)

I was able to run shell scripts emulating the inputs directly from linux shell but not from my application:

Runtime.getRuntime().exec(cmd)

returns

cannot open /dev/input/event1, permission denied

This occurs if cmd is sh /path/script-emulating-events or sendevent /dev/input/event1 xxxx x x.

Since the application has android.uid.system for shared user id, it shouldn't be an android privilege issue.

Any idea?

There appears to be something new in Jelly Bean! The input commands have improved:

usage: input ...
       input text <string>
       input keyevent <key code number or name>
->       input tap <x> <y>
->       input swipe <x1> <y1> <x2> <y2>

It worked fine on 4.1.2

In order to run those commands, you have to root your device.
