### 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`
|
|
|
|
|
|
### 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"`
