Also get the same issue with normal mini touch:

`C:\Users\dj-lu\OneDrive\Documents\Coding\PythonScripts\BeatStar\minitouch>adb shell getprop ro.product.cpu.abi | tr -d '\r' arm64-v8a

Getting the same error on two devices: Non-rooted Pixel 7 Pro Rooted Redmi Note 8

Try giving permission by executing chmod +x /data/local/tmp/minitouch ?

Thanks that seems to have fixed the permision issue with minitouch for my rooted device.

Still having permision denied through pyminitouch though, now getting the following error:

ls: /data/local/tmp/katana-e4a04767ff49f2a3c49a9430b2e917c9: Permission denied

Tried the following but no luck:

C:\Users\dj-lu>adb shell chmod +x /data/local/tmp/katana-e4a04767ff49f2a3c49a9430b2e917c9 chmod: /data/local/tmp/katana-e4a04767ff49f2a3c49a9430b2e917c9: Permission denied

Command ran when I elevated to root, but still permision denied when running pyminitouch

Today I tried granting adb root access via modifying my build.prob file to include

ro.debuggable=1 ro.secure=0

This unfortunately didn't solve my issues, and I am still getting permission denied. Is anyone else having the same issue?

EDIT:

I deleted the folder /data/local/tmp/katana-e4a04767ff49f2a3c49a9430b2e917c9

Upon running I now get the following error

Seems granting SU to adb didn't work?

Manage to fix the issue following the following steps. (I'm using android 10+)

After building the app with:

gradle gradlew installDebug

Install the application using:

ADB install C:\<path to folder>\STFService.apk\app\build\outputs\apk\debug\app-debug.apk

Now start the service, note that Oreo (26+) requires services in the foreground, thus use the following:

adb shell am start-foreground-service --user 0 -a jp.co.cyberagent.stf.ACTION_START -n jp.co.cyberagent.stf/.Service

or if getting user error,

adb shell am start-foreground-service -a jp.co.cyberagent.stf.ACTION_START -n jp.co.cyberagent.stf/.Service

then follow the rest of the steps

Note, you will still get permission denied, but pyminitouch will then connect via the STF socket.

Be sure that the socket is running before calling pyminitouch
