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

jadx

Dex to Java Decompiler

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)
     --cfg           - save methods control flow graph to dot file
     --raw-cfg       - save methods control flow graph (use raw instructions)
 -v, --verbose       - verbose output
 -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"
