We need the android.os.Context object for a number of purposes like inter-activity communication, starting new activities and get package name of the android mobile app. An activity has the context object injected into it by the Android OS. But what will you do if you want to access the Context in non-acivity or plain java class.

In this case we shall need to create a factory of context object which allows any Java class in our app to access the context object in static way whenever needed. The basic idea is same that of a singleton class with static access method. We will not run into multi threading issues when using the way demonstrated in this Android tutorial.
