**jadx** - Dex to Java decompiler
|
|
|
|
Command line and GUI tools for producing Java source code from Android Dex and Apk files
|
|
|
|
> [!WARNING]
|
|
> Please note that in most cases **jadx** can't decompile all 100% of the code, so errors will occur.<br />
|
|
> Check [Troubleshooting guide](https://github.com/skylot/jadx/wiki/Troubleshooting-Q&A#decompilation-issues) for workarounds.
|
|
|
|
**Main features:**
|
|
- decompile Dalvik bytecode to Java code 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)
