DexExposed

A program to flip every private, protected and package-private access flag to public in an Android dex file!

      Prints the usage information.
      Default: false

Reasoning

While instrumenting Android malware, I often want to write 'plugins' in Java to interact with it. The plugins are written using the malware's own code as an API and this allows me to achieve Xposed-like functionality. In many cases though, I find that it's near impossible to do this as many items are private, protected, or package-private. It's annoying, so I created this tool to save me the headache of having to manually edit the items I needed to be public.
