How to get data from someone else's application using a Service?

Question

Android

How can I implement the receipt of numerical data from someone else's application? I know that there are applications that not only find numerical data, but can also change them. The Service must work in the background and write the data of another running application to the database every second. Interested only in the implementation of data acquisition. PS Getting data like SB Game Hacker ( https://androidapplications.ru/programs/2403-sb-ga... with the difference that you don't need to change the values)

Answer 1

This is far from always possible without root, analysis (decompilation, disassembly) of this application is needed, and if you see an application that can receive or change this data, then study it.
