jadx - Dex to Java decompiler

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

See these features in action here: jadx-gui features overview

After download unpack zip file go to bin directory and run:

  • jadx - command line version
