jadx - Dex to Java Decompiler

jadx - Dex to Java decompiler

Command line and GUI tools for produce Java source code from Android Dex and Apk 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 jadx on itself:
cd build/jadx/
bin/jadx -d out lib/jadx-core-*.jar
bin/jadx-gui lib/jadx-core-*.jar

jadx[-gui] [options] <input file> (.dex, .apk, .jar or .class)
 -d, --output-dir           - output directory
 -j, --threads-count        - processing threads count
 -r, --no-res               - do not decode resources
 -s, --no-src               - do not decompile source code
 -e, --export-gradle        - save as android gradle project
     --show-bad-code        - show inconsistent code (incorrectly decompiled)
     --no-replace-consts    - don't replace constant value with matching constant field
     --escape-unicode       - escape non latin characters in strings (with \u)
     --deobf                - activate deobfuscation
     --deobf-min            - min length of name
     --deobf-max            - max length of name
     --deobf-rewrite-cfg    - force to save deobfuscation map
     --deobf-use-sourcename - use source file name as class name alias
     --cfg                  - save methods control flow graph to dot file
     --raw-cfg              - save methods control flow graph (use raw instructions)
 -f, --fallback             - make simple dump (using goto instead of 'if', 'for', etc)

 -h, --help                 - print this help
 jadx -d out classes.dex


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"

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
