A class that inherits Activity also inherits getResources(). If you have a class that is an Activity (or a derivative thereof) you have access to this method (via inheritance, a really, really basic concept in object oriented programming. If you have a class that isn't a derivative of such a class, you need to grant access to such a context for access to said resources.

If you need more information about inheritance, polymorphism, or etc. regarding object oriented programming, I suggest referring to various websites or school curricula touching upon such issues.
