title: Best practices on Navigation Drawer use
body: <p>I was reading about <code>Navigation Drawer</code> and it was not until now that I came into this question: If my top views are going to be accessible through the <code>Navigation Drawer</code>, should I code each of them as <code>Fragments</code> or as <code>Activities</code>?</p>
  
  <p>I want to know the way it was intended to be used, with <code>Fragments</code> or with <code>Activities</code></p>
