setDisplayHomeAsUpEnabled() error: non-static method cannot be referenced from a static context

Question

I have two parts of codes. One has the error, but the other doesn't.

ActionBar theActionBar = getSupportActionBar();
if (theActionBar != null) {
    // error: non-static method cannot be referenced from a static context
    ActionBar.setDisplayHomeAsUpEnabled(true);
}

.

getSupportActionBar().setDisplayHomeAsUpEnabled(true);

.

Does anyone happen to know how to explain this?

`ActionBar.set` compared to `theActionBar.set`... Use the actual instance variable, not the class — OneCricketeer, Jul 30 '16 at 13:50

Your error says it all. Just change this line:

ActionBar.setDisplayHomeAsUpEnabled(true);

to

theActionBar.setDisplayHomeAsUpEnabled(true);

or just change your code to look like this:

if(getSupportActionBar() != null)
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
