Unterschied zwischen GetContext und GetApplicationContext in Android

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().
