What JADX is
JADX is a free tool that produces Java source code from Android Dex and APK files, with both command-line and graphical interfaces. It also decompiles AAR, AAB, and ZIP files and can decode AndroidManifest.xml and resources.arsc. An included deobfuscator offers mapping and identifier-renaming options. The GUI provides syntax highlighting, navigation to declarations, usage lookup, and full-text search. Its debugger supports stepping, breakpoints, and changes to register values and object fields, but requires adb and a debuggable app or a rooted device or emulator. Developers can use JADX as a library in Java projects, and the CLI can manage plugins. Downloaded releases require 64-bit Java 11 or later. JADX warns that it cannot recover all code in most cases, so decompilation errors can occur. It runs on Linux, macOS, and Windows and is licensed under Apache 2.0.
