Difference between getContext() , getApplicationCo

Question

What is the difference between getContext() , getApplicationContext() , getBaseContext() , and "this"?

Though this is simple question I am unable to understand the basic difference between them. Please give some easy examples if possible.

Answer 1

Context provides information about the Actvity or Application to newly created components.

Relevant Context should be provided to newly created components (whether application context or activity context)

Since Activity is a subclass of Context, one can use this to get that activity's context

Answer 2
