Building jadx from source
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

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"
- command line (example for linux):
