I m confused about context

I don't know when to use someActivityClass.this and when to use getApplicationContext() to set as a Context ! What is the difference ? When do I have to use the first option and when do I have to use the second option ?

Its very small but very important difference in android application code.

android.content.Context

Context is an abstract class whose allows access to application-specific resources and classes, as well as up-calls for application-level operations such as launching activities, broadcasting and receiving intents, etc.

1. getApplicationContext(): Application context is attached to the application's life-cycle.

2. LoginActivity.this : Activity context is live with the Activity's life-cycle and can be destroyed if the activity's onDestroy.

3. getBaseContext() : This Context is available to widgets and Views.

For more detail :

When to call activity context OR application context?

Difference between getContext() , getApplicationContext() , getBaseContext() and "this"

Getting the Application Context
