title: Android drag margin for navigation drawer is off screen
body: <p>I have recently created an app called Hoops and I have been developing it for quite some time now. However, the main problem that I seem to be getting, is that the navigation drawer's swipe margin is off screen and other users find it incredibly hard to use the navigation drawer's swipe feature. The menu button works just fine though. I have looked at other tutorials online and all of them seem to be showing the same answer as the one in the forum I have linked: <a href="https://stackoverflow.com/questions/16988597/set-drag-margin-for-android-navigation-drawer">Set drag margin for Android Navigation Drawer</a> 
  However, I have tried this solution, and it does not seem to be working for me. If anyone has any ideas why it is not working please can you help me out. Here is the coding for the Main activity with the navigation drawer below:</p>

  <p>If anyone wants a live example of the navigation drawers swipe feature not working you can test out my app in the app store. Here is the link: <a href="https://play.google.com/store/apps/details?id=com.jehan.sportstutorials" rel="nofollow noreferrer">https://play.google.com/store/apps/details?id=com.jehan.sportstutorials</a> </p>
  
  <p>Summary: Does anyone know how to increase the navigation drawers drag margin, however not following the conventional methods stated in the link in my first paragraph? Help would be appreciated. </p>
