jadx - Dex to Java decompiler

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

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

Upcoming unstable features:

• smali debugger (thanks to @LBJ-the-GOAT), check wiki page for setup and usage

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

Download

• release from github:
• latest unstable build

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").

2. macOS

    brew install jadx

Build from source

JDK 8 or higher must be installed:

git clone https://github.com/skylot/jadx.git

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

--deobf-use-sourcename - use source file name as class name alias
--deobf-parse-kotlin-metadata - parse kotlin metadata to class and package names
--rename-flags - fix options (comma-separated list of):
'case' - fix case sensitivity issues (according to --fs-case-sensitive option),
