What is 'Context' on Android?

Question

In Android programming, what exactly is a Context class and what is it used for?

I read about it on the developer site, but I am unable to understand it

Answer 1

The class android.content.Context provides the connection to the Android system and the resources of the project. It is the interface to global information about the application environment.

The Context also provides access to Android Services, e.g. the Location Service.

Activities and Services extend the Context class.
