title: Android toolbar not showing overflow menu

I've tried to follow the steps <a href="http://developer.android.com/training/appbar/setting-up.html" rel="noreferrer">here</a>, to create a toolbar for my application.  However, it's not showing the three dots overflow menu (which I thought was automatic). </p>
