A fork of jadx with support for editing Java source code of APK's, and then recompiling them. Inspired by dnSpy, but for Android Java instead of .NET.
apkSpy allows you to recompile individual methods of classes, so you can recompile only small pieces, regardless of whether the other parts of the application are compiling or not. Once you've made your changed you can export it as an APK.
- Currently you cannot edit Smali bytecode. This would be very useful, as you can edit a method even if that method itself does not compile.
- You can only edit methods. It would be great to have support for editing member fields.
- The ability to create and delete classes, as well as create and delete new methods.
- Classes within the
android.*packages cannot be edited.
Below is the README for jadx.
After compiling this project from source (there will be released in the future), load an APK, open up any class, right-click within a method and then click "Edit Method Java".
To save your changes, first ensure your Android SDK path is set. You can find this by going in the menu bar apkSpy -> Preferences. Then, your changed can be recompiled by going to apkSpy -> Save APK. If all goes well, it should pop up saying the recompiling has been successful. You now have a patched APK!
jadx - Dex to Java decompiler
Command line and GUI tools for produce Java source code from Android Dex and Apk files
- latest unstable build:
- release from github:
- release from bintray:
After download unpack zip file go to bin directory and run:
jadx- command line versionjadx-gui- graphical version
On Windows run .bat files with double-click
Note: ensure you have installed Java 8 64-bit version
- PyJadx - python binding for jadx by @romainthomas
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
You can install using brew:
brew install jadx
Run jadx on itself:
cd build/jadx/
bin/jadx -d out lib/jadx-core-*.jar
# or
bin/jadx-gui lib/jadx-core-*.jar
jadx[-gui] [options] <input file> (.apk, .dex, .jar, .class, .smali, .zip, .aar, .arsc)
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-debug-info - disable debug info
--no-inline-anonymous - disable anonymous classes inline
--no-replace-consts - don't replace constant value with matching constant field
--escape-unicode - escape non latin characters in strings (with \u)
--respect-bytecode-access-modifiers - don't change original access modifiers
--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
--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
--version - print jadx version
-h, --help - print this help
Example:
jadx -d out classes.dex
jadx --rename-flags "none" classes.dex
jadx --rename-flags "valid,printable" classes.dex
These options also worked on jadx-gui running from command line and override options from preferences dialog
- Reduce processing threads count (
-joption) - 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):
