JDK 8 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

macOS

You can install using brew:

brew install jadx

Run

Run jadx on itself:

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

  --deobf                             - activate deobfuscation
  --deobf-min                         - min length of name, renamed if shorter (default: 3)
  --deobf-max                         - max length of name, renamed if longer (default: 64)
  --deobf-rewrite-cfg                 - force to save deobfuscation map
  --deobf-use-sourcename              - use source file name as class name alias
  --rename-flags                      - what to rename, comma-separated, 'case' for system case sensitivity, 'valid' for java identifiers, 'printable' characters, 'none' or 'all'
  --fs-case-sensitive                 - treat filesystem as case sensitive, false by default
  --cfg                               - save methods control flow graph to dot file

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"
