Difference between getContext() , getApplicationContext() , getBaseContext() and “this”

by

  • View.getContext(): Returns the context the view is currently running in. Usually the currently active Activity.

  • Activity.getApplicationContext(): Returns the context for the entire application (the process all the Activities are running inside
    of). Use this instead of the current Activity context if you need a
    context tied to the lifecycle of the entire application, not just the
    current Activity.

  • ContextWrapper.getBaseContext(): If you need access to a Context from within another context, you use a ContextWrapper. The
    Context referred to from inside that ContextWrapper is accessed via
    getBaseContext().
