jadx - Dex to Java decompiler
Command line and GUI tools for produce Java source code from Android Dex and Apk files
Downloads
- unstable
- from github
- from sourceforge
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
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 -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) -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"
- command line (example for linux):
Contribution
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
And any other comments will be very helpfull, because at current stage of development it is very time consuming to find new bugs, design and implement new features. Also I need to prioritize these task for complete most important at first.
