jadx - Dex to Java decompiler

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

❗❗❗ Please note that in most cases jadx can't decompile all 100% of the code, so errors will occur. Check Troubleshooting guide for workarounds

Main features:

  • decompile Dalvik bytecode to java classes from APK, dex, aar, aab 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
  • smali debugger, check wiki page for setup and usage

Jadx-gui key bindings can be found here

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


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 11 or later 64-bit version. For Windows, you can download it from oracle.com (select x64 Installer).


  1. Arch linux
    sudo pacman -S jadx
  2. macOS
    brew install jadx
  3. Flathub
    flatpak install flathub com.github.skylot.jadx

Use jadx as a library

You can use jadx in your java projects, check details on wiki page

Build from source

JDK 11 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
