Enumerating content providers


Much like enumerating activities and packages, drozer also provides some modules for listing all of the content providers and some information on them. The following recipe talks about how to do this using the app.provider.info module.

How to do it...

Let's get started enumerating content providers.

  1. Execute the following command from your drozer terminal:
