On Android, context can be used for many operations, but most of the time it is used to load and use resources. This is why all widgets accept a context parameter in their constructor.

Often, when our classes and methods need to be used in the context, we pass on the context of activity.[Java] @Override protected void onCreate (Bundle state)
