    Context is an interface!

    According to source code:

    Interface to global information about an application environment. This is an abstract class >whose implementation is provided by the Android system. It allows access to application-specific resources and classes, as well as up-calls for application-level operations such as launching activities, broadcasting and receiving intents, etc.

    See http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.0.4_r1.2/android/content/Context.java#Context for the best understanding
