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

In Java, we say this keyword refers to the state of the current object of the application.
Similarly, in an alternate we have Context in Android Development.

This can be defined either explicitly or implicitly,

Context con = this;

getApplicationContext();

getBaseContext();

getContext();
