Question

I am trying to send touch events using batch files (.bat) and the adb shell.

I tried to re-send events I get from the adb shell getevents, and it doesn’t work even though the command passes without errors.
Any ideas?

How do I simulate a touch-event and release-event on a given (x,y) coordinate using the ADB shell?

Since it seems to change depending on the Android version, I suggest you to follow these instructions :

1. Start dump motion event you need to reproduce:

   ~$ adb shell getevent | grep event2
   

   grep is very useful to filter output.

2. Do motion event you want to reproduce;

3. Then just convert all values from hex in dump to decimal values! 🙂

To find what eventX is working for you do following:

1. Start terminal and type:

   ~$ adb shell getevent
   

You will see quickly moving traces with for example /dev/input/event4 ……

2. Touch screen once

You must see between event4 few eventX and these eventX right in the moment of the touch

will be yours input interface for reproducing motion events! 🙂
