How can I get the value of a variable when debugging an android app?

Question

Android

Suppose I know that in this piece of code (on the screen), important data is received from the server, then this data, as I understand it, is encrypted thanks to obfuscation, and then in the native class (to which I do not have access) the whole thing is decrypted and displayed to the screen.
So the question itself is how can I get unencrypted data from the server, I see only two ways, because in the native class I can’t see anything, 1st way, it’s using something to see unencrypted data (actually the question itself is in header), or go through all the methods indicated here due to obfuscation and slowly decrypt (although I can’t even see the encrypted information, because the debugger is at odds, by the way, it doesn’t matter which debugger, they are all kind of similar).
