I am trying to change the name of the app using its APK, but the problem is when I decompile\recompile it (using apkeasytool) and install it, it crashes. This behavior could be because when the app starts it somehow checks if the app is compiled with the original signature.
I have tried to see the app logic on Jadx but still, many method names and strings are encoded. I know this is a way to protect APKs from repack but I know this can be cracked I am learning about Frida and let's see if I can crack that. And if you have any suggestions please feel free to tell me.
Use Apk Editor and Apktool-M on mobile to change the name
