Can someone clarify Android context references?

My misunderstanding continues ...

Can anyone cite references for the proper use of get*Context()? I get conflicting recommendations about using getBaseContext(), getApplicationContext() and getContext() and my understanding is that using this is a convenience to get*Context(). I would like to study more specifically of what Dalvik is intending its object and access methods.

I had code reviews that changed my calls to getBaseContext() to getApplicationContext(), now I am seeing suggestions to use this.

Read this article. It describe why we should use getApplicationContext() rather than Activity's this

This is summary of the article:

In summary, to avoid context-related memory leaks, remember the following:

  • Do not keep long-lived references to a context-activity (a reference to an activity should have the same life cycle as the activity itself)
  • Try using the context-application instead of a context-activity
