Packages and Binaries:

jadx

This package contains a Dex to Java decompiler. It contains a command line and GUI tools for produce Java source code from Android Dex and Apk files.

Main features: - decompile Dalvik bytecode to java classes from APK, dex, aar and zip files - decode AndroidManifest.xml and other resources from resources.arsc - deobfuscator included

jadx-gui features: - view decompiled code with highlighted syntax - jump to declaration - find usage - full text search
