title: I cannot add new destination into navigation component in android studio
body: <p>I got some problems when I create a navigation graph to control fragments, the problem is that whenever I add any new destination to this graph, this destination will not be displayed and I cannot control them. Can you let me know when I went wrong and how to fix them? Thanks!</p>
