Run ADB command inside app code

Question

I'm developing an app that will only be used inside the AVD. My objective is automate some tasks. Sometimes, the "back button" needs to be pressed. I know that I can do it using the adb shell. However, I would like make it from my app code. I've tryed to command below, but I'm getting an "Permission denied" error.

Runtime.getRuntime().exec("adb shell input keyevent 4");

Do you have any idea how I can do it or give the necessary permissions?

Answer 1

This thread might help you sorting issues. Because as per my perspective you need root permission for that to execute commands or you can give it a try using processbuilder method.
