I understand how to get to root with su for the GPIO.
For the other options, how do you do it ?
2 Let the 3rd application as system process
Is this one just putting the app in priv-app in the rom ?
3 Open the permission for 3rd application on system
This one i don’t know how. Can you point me in the right direction ?
You also need a system signature for the app.
You need to modify source code of the direction system/sepolicy
Thank you, I will try the 2nd way.
Hello Terry ,
My understanding is that the gpio path in linux systems is “/sys/class/gpio/”.
I would like to know is it the same for even android systems?
Yes, it’s the same.
Thank you very much Terry.
