title: Activities or Fragments in NavigationView?
body: <p>I have a NavigationView used as a slide-in menu. Each of that menu items is a use case itself, therefore I tend to using activities containing different fragments.</p>
  
  <p>But nearly every example of <code>NavigationView/NavigationDrawer</code> uses fragments, so I don't know what to use here.</p>
  
  <p>I thought different use cases should be "encapsulated" in own activities, therefore I don't really understand why <code>Navigation[View/Drawer]</code> uses fragments. And that leads me to my question: for a <code>Navigation[View/Drawer]</code> containing completely separate use cases - should I link to activities or fragments?</p>
