Android toolbar not showing overflow menu
<p>I'm new to android apps and I'm hoping someone with keen eyes can spot what I'm doing wrong.  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>

<p><strong>Here's what I see:</strong></p>
