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.xmland other resources fromresources.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
- release from github:
- latest unstable build
After download unpack zip file go to bin directory and run:
jadx- command line versionjadx-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).
- Arch linux
sudo pacman -S jadx
- macOS
brew install jadx
You can use jadx in your java projects, check details on wiki page
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

Plugin options (-P<name>=<value>):
1) dex-input (Load .dex and .apk files)

These options also worked on jadx-gui running from command line and override options from preferences dialog
