Debug Android Permissions

I would like to analyze deeply the behavior of the android permissions. When a permission is granted or not, what android do, etc. I have some ideas, but I would like to know which one could be the easiest one, or any new idea, or if some similar works have already been done. So I thought about: - frida - android studio using the debugging - making in local a java script using the same logic than in the aosp The logcat in Android Studio is very powerful, I can see the ActivityTaskManager and GrantPermissionsActivity for example. But I don't know what happened to call them, why these parameters etc. So, if you have any ideas, any tips, any documentations, I'm interested in. Thank you.
