android - setsupportactionbar() throws error

Question

I tried following the steps for displaying a drawer above the action bar but below the status bar. The steps found here: display over the ActionBar/Toolbar and under the status bar?

But after implementing the code, the following error was thrown:
error: cannot find symbol method setSupportActionBar(Toolbar)
I've searched on Google for this exact error and not a single result.

I'm using Android Studio (1.1) and have tried using "Clean Build"
I'm using import android.support.v7.widget.Toolbar;

Toolbar toolbar = (Toolbar) findViewById(R.id.actionbar);
setSupportActionBar(toolbar); //error

Hopefully, someone recognizes this error and has a quick answer for it - otherwise I can provide more information if requested.

Edit:

Recently ActionBarActivity has been deprecated in favor of ActionBarCompat. You should use the new one, and use as the ActionBarCompat themes, E.g. Theme.AppCompat.Light

you class has to extend ActionBarActivity instead of Activity, in order to use the method setSupportActionBar
