jadx - Dex to Java decompiler

Command line and GUI tools for produce Java source code from Android Dex and Apk files

Main features:

  • decompile Dalvik bytecode to java classes from APK, dex, aar and zip files
  • decode AndroidManifest.xml and other resources from resources.arsc
  • deobfuscator included

jadx-gui features:

  • view decompiled code with highlighted syntax
  • jump to declaration
  • find usage
  • full text search

See these features in action here: jadx-gui features overview

Download

After download unpack zip file go to bin directory and run:

  • jadx - command line version
  • jadx-gui - UI version

On Windows run .bat files with double-click
Note: ensure you have installed Java 8 or later 64-bit version. For windows you can download it from adoptopenjdk.net (select "Install JRE").

Install

  1. Arch linux
        sudo pacman -S jadx
  2. macOS
        brew install jadx

Build from source

JDK 8 or higher must be installed:

git clone https://github.com/skylot/jadx.git
cd jadx
./gradlew dist

(on Windows, use gradlew.bat instead of ./gradlew)

Scripts for run jadx will be placed in build/jadx/bin and also packed to build/jadx-<version>.zip
