title: Android Navigation Drawer: open deep fragment from notification
body: <p>first sorry for my rusty English !</p>
  
  <p>This is a doubt I have had for some time now and although my skills on Android have been getting better I haven't found an elegant solution for this issue:</p>
  
  <p>Lets say an application uses the Navigation Drawer pattern and has three levels of navigation:
  Home -> Posts -> Post details</p>
  
  <p>When I open the App from the launcher I add the Home Fragment. From here the user can navigate all the way down to a given "post" using fragment transactions.</p>
  
  <p>Now imagine there is some kind of notification that is letting me know something happened on a specific post: How would you create a "synthetic" back-stack when opening the app from the notification ? What I mean is:</p>
  
  <p>1- Open the app from the notification</p>
  
  <p>2- The app opens on Post Details</p>
  
  <p>3- Back navigation has to be > Posts > Home</p>
  
  <p>Thanks a lot in advance !</p>
