What android application can track the activities of another?

Question

Android

You need to trace all the tails of the application. What and where it writes during installation and use. Is there a right tool? After deleting by regular means, manually deleting the files found by the search and reinstalling, it still sees that this is not the first time on a smartphone. But if you backup the / data partition before installation, and then restore it, then the application is like new. Tell me which way to dig.

Answer 1

I don’t know about tracking on UNIX, I didn’t have anything to do, but decompilation of the application is possible, I had it, although I won’t say that it’s easy if the application is not small.
