jadx - Dex to Java decompiler

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

Downloads

After download unpack zip file go to bin directory and run:

  • jadx - command line version
  • jadx-gui - graphical version

On Windows run .bat files with double-click
Note: ensure you have installed Java 8 64-bit version

Building from source

Java 8 JDK 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

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
 -ds, --output-dir-src       - output directory for sources
 -dr, --output-dir-res       - output directory for resources
 -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-imports           - disable use of imports, always write entire package name
      --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)
 -v,  --verbose              - verbose output
 -h,  --help                 - print this help
Example:
 jadx -d out classes.dex

These options also worked on jadx-gui running from command line and override options from preferences dialog

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"
