ActionBar setDisplayHomeAsUpEnabled (true) vs setDisplayShowHomeEnabled (true). Who cares?

Question

The name pretty much speaks for itself. What are the exact differences? I will lay out the sample code below.

actionbar = getSupportActionBar(); actionbar.setDisplayHomeAsUpEnabled(true); actionbar.setDisplayShowHomeEnabled(true); 

Answer 1

The documentation pretty much explains itself.

ActionBar.setDisplayShowHomeEnabled() indicates whether the Home button is displayed.

ActionBar.setDisplayHomeAsUpEnabled() indicates whether the Home button has an arrow used for Up Navigation next to it.
