Decompilation is no longer bound to a single CPU core. Advanced Apktool v4.2.0 introduces a parallel processing pipeline that distributes the extraction and disassembly of classes.dex files across all available CPU threads.

I’ve been using Advanced APKTool (AAT) for years, and v4.2.0 continues the tradition of being one of the most accessible GUIs for APK modification. If you are looking to decompile, edit, or recompile Android applications without messing with command-line scripts, this is the tool to have.
One compelling use case involves bringing old Android applications back to life.

This approach works because APKTool can extract and modify compiled resources without requiring the original Java source files.
