Got `Source Code does not match bytecode` debug a Reversed Android app

Question

Reverse an .apk file following This Article

1. Open ApkStudio, edit AndroidManifest.xml to allow debug and Build a new Apk file
2. Got source code with dex2jar and jd-gui
3. Create an project in Android Studio
4. Put source code into the project folder
5. install the apk in an Emulator
6. run the app and start Attach Debugger in Android Studio

Breakpoints successfully reached, but got no debug information with a Source Code does not match bytecode warning.

What's wrong with my operations?

Answer 1

The source code you got is not a perfect match, it is representative. You will likely want to debug in smali, not Java. The smali plugin for AndroidStudio works really well for this.
