Is it possible to make a clone of the application with all the data?

Question

Java

Hello everyone, I'm interested in the question of whether it is possible to make an application clone with all its data, including sessions, settings, etc. on another phone (for example, with exactly the same OS).
I read a lot where they write that Root is needed for this, it’s not a problem, but the method of copying the application with its data is interested in how to do it correctly, in what language you need to write such a tool, maybe someone will tell you where all the application data is stored to do it yourself This. Give me a clue please :)
