It is a tool for reengineering 3rd party, closed, binary Android apps. It can decode resources to nearly original form and rebuild them after making some modifications; it makes possible to debug smali code step by step. Also it makes working with app easier because of project-like files structure and automation of some repetitive tasks like building apk, etc.

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

Features:

• decoding resources to nearly original form
• smali debugging: SmaliDebugging
• helping with some repetitive tasks

Road Map:

• Fix bugs located here: https://github.com/iBotPeaches/Apktool/issues?state=open
• Change the way public.xml is decompiled. Some elements are hardcoded in the java and have to retain the same ID, while others are strictly resources and aapt can re-generate. This method would be cleaner and decrease the amount of failures, but is a big rewrite.
