apkSpy

apkSpy is a powerful tool designed for editing and recompiling Java source code from Android APK files, providing granular control over individual methods within classes. It extends the functionalities of jadx by allowing users to modify and recompile specific parts of the application while maintaining the integrity of the rest. Key features include the capability to export changes as a new APK, although it currently lacks support for editing Smali bytecode and managing class structures.
