title: Update Navigation drawer listview
body: <p>My application implements a navigation drawer to change fragments. What I need now is to update the navigation drawer items if the user is logged in </p>
  
  <p>For example :
  logged in navigation items look like this</p>
  
  <p>Home
  My Info
  Logout</p>
  
  <p>logged off navigation items look like this</p>
  
  <p>Home
  Register
  Login</p>
  
  <p>The set up of my project is 
  a Base activity which extends Navigation fragment and changes to a current fragment based on the selected navigation drawer item.</p>
  
  <p>All my other files are fragments which change depending on the navigation drawer item selected.</p>
  
  <p>I have this kind of working but navgation drawer only updates when I log in then close the app completely and then re start it.</p>
