**jadx** - Dex to Java decompiler

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

:exclamation::exclamation::exclamation: Please note that in most cases **jadx** can't decompile all 100% of the code, so errors will occur. Check [Troubleshooting guide](https://github.com/skylot/jadx/wiki/Troubleshooting-Q&A#decompilation-issues) 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](https://github.com/skylot/jadx/wiki/Smali-debugger) for setup and usage

Jadx-gui key bindings can be found [here](https://github.com/skylot/jadx/wiki/JADX-GUI-Key-bindings)

See these features in action here: [jadx-gui features overview](https://github.com/skylot/jadx/wiki/jadx-gui-features-overview)

### Download
- release from [github: ![Latest release](https://img.shields.io/github/release/skylot/jadx.svg)](https://github.com/skylot/jadx/releases/latest)
- latest [unstable build](https://nightly.link/skylot/jadx/workflows/build/master)

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](https://www.oracle.com/java/technologies/downloads/#jdk17-windows) (select x64 Installer).

### Install
1. Arch linux
    ```bash
        sudo pacman -S jadx
    ```
2. macOS
    ```bash
        brew install jadx
    ```

### Use jadx as a library
You can use jadx in your java projects, check details on [wiki page](https://github.com/skylot/jadx/wiki/Use-jadx-as-a-library)

### 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`
