I’m trying to reverse engineer an apk (just to learn) and I want the program to think I’m a VIP. I think I found the main logic

I think I should modify the getMember, getConsumerMember, and getLevel methods at the same time, but the first two accept a member variable, and I don’t know how to modify it.

i have no idea
sorry for my english
i use google translate

I once if-nez v0, :cond_42 assigned the value of v0 to 1. When I compiled it, it crashed on a specific page. I think it detected my memberlevel and I was still an ordinary user. Even after I deleted the killprocess function, it also crashed.
It’s hard for me to express my problem accurately

I successfully changed the getNickname part to what I want, it’s very simple:>
btw please forgive me if this is a stupid question, I have never learned Android development or Java, I will learn slowly, and I also want to practice it as soon as possible
