Permission denied - when replaying touch events

[usamaabrar22]

Hi,
I've tried this code and was able to record touch events on my Android 8.0 (without root).
However, executing the replay_touch_events.sh file do pushes the file to phone but doesn't execute it on phone. It gives error "Permission denied".
I have checked this on Genymotion emulator as well, and the progress and error is same.

I have carefully checked this problem mentioned in other similar "Issues" section of this repo. but apparently no solution mentioned there solved my problem.

This error is weird because adb shell input tap x y works fine.
Can you help me on this issue? I want to know how to handle this "Permission Denied" error.

@usamaabrar22 could you try using the executable for 64 bit? Could you also show a PrintScreen of the error message?

I'm seeing a similar error when trying to run replay_touch_events.sh on my Pixel:

Looking for touchscreen device...
/dev/input/event3
/dev/input/event2
Touchscreen device found! -> /dev/input/event2
---/data/local/tmp/mysendevent-arm64---
recorded_touch_events.txt: 1 file pushed, 0 skipped. 50.5 MB/s (27010 bytes in 0.001s)
could not open /dev/input/event2, Permission denied

Changing permissions using chmod seems to have no effect

adb shell chmod +x /data/local/tmp/mysendevent-arm64

@saket how did you end up solving the issue, I have the same issue on my pixel 4

@theochampion I unfortunately couldn't

I believe it is due to a new security policy. See openstf/minitouch#49

Workaround:
If you have a rooted device, you can insert su -c in adb shell command like this to run binaries with root privileges.

su -c has 0 effect sadly.

It works on my phone.
