Apktool

This is the repository for Apktool. The website is at the apktool.org repository.

CI Software License

Apktool is a tool for reverse engineering third-party, closed, binary, Android apps. It can decode resources to nearly original form and rebuild them after making some modifications; it makes it possible to debug smali code step-by-step. It also makes working with apps easier thanks to project-like file structure and automation of some repetitive tasks such as building apk, etc.

Apktool is NOT intended for piracy and other non-legal uses. It could be used for localizing and adding features, adding support for custom platforms, and other GOOD purposes. Just try to be fair with the authors of an app, that you use and probably like.

Branches

  • main - Apktool 3.x branch
  • 2.x - Maintenance branch for Apktool 2.x releases
