How to change the address to which the application sends data?

Question

Android

Let's say there is an application on android that collects some data about the operation of the phone and stores it in memory. At a certain time, this data goes to the server, where the user can view it.
The question is: How to find out what address it all goes to, and how to change this address? Roughly speaking, so that the data does not go to the server that was originally intended for this.
And I think that on an alternative server you need to create some kind of structure so that it understands what kind of data it comes to, and how to display them in a readable form?

Answer 1

Launch the application and monitor traffic. You need to make sure that the Internet uses only this application.
Well, or collect all the addresses, sort them out by whois, for example, and determine which one corresponds to the desired application.
You can try to disable the Internet for all applications except the one you need. It will be easier to sniff traffic.
