Ok, so I download an app from Google Play and launch it. I'd like to see the behavior of this app, i.e. new directories or files changed/created by this app throughout the filesystem.
Is there, for example, a special app which can track other's apps behavior? Or should I just make a copy of a filesystem before and after running the app, and just compare them? Any other ideas?
My device is rooted, runs Android 7.0 (MIUI9 8.2.8).
