**jadx** - Dex to Java decompiler

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

![jadx-gui screenshot](http://skylot.github.io/jadx/jadx-gui.png)

### Downloads
- [unstable](https://drone.io/github.com/skylot/jadx/files)
- from [github](https://github.com/skylot/jadx/releases)
- from [sourceforge](http://sourceforge.net/projects/jadx/files/)


### Building from source
    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`


### Run
Run **jadx** on itself:

    cd build/jadx/
    bin/jadx -d out lib/jadx-core-*.jar
    #or
    bin/jadx-gui lib/jadx-core-*.jar


### Usage
```
jadx[-gui] [options] <input file> (.dex, .apk, .jar or .class)
options:
 -d, --output-dir        - output directory
 -j, --threads-count     - processing threads count
 -f, --fallback          - make simple dump (using goto instead of 'if', 'for', etc)
 -r, --no-res            - do not decode resources
 -s, --no-src            - do not decompile source code
     --show-bad-code     - show inconsistent code (incorrectly decompiled)
     --cfg               - save methods control flow graph to dot file
     --raw-cfg           - save methods control flow graph (use raw instructions)
 -v, --verbose           - verbose output
     --deobf             - activate deobfuscation
     --deobf-min         - min length of name
     --deobf-max         - max length of name
     --deobf-rewrite-cfg - force to save deobfuscation map
 -h, --help              - print this help
Example:
 jadx -d out classes.dex
```

### Troubleshooting
##### Out of memory error:
  - Reduce processing threads count (`-j` option)
  - Increase maximum java heap size:
    * command line (example for linux):
      `JAVA_OPTS="-Xmx4G" jadx -j 1 some.apk`
    * edit 'jadx' script (jadx.bat on Windows) and setup bigger heap size:
      `DEFAULT_JVM_OPTS="-Xmx2500M"`


### Contribution

To support this project you can:
  - Post thoughts about new features/optimizations that important to you
  - Submit bug using one of following patterns:
    * Java code examples which decompiles incorrectly
    * Error log and link to _public available_ apk file or app page on Google play

And any other comments will be very helpfull,
because at current stage of development it is very time consuming
to **find** new bugs, design and implement new features.
Also I need to **prioritize** these task for complete most important at first.
