• Steps to reproduce the problem (including sample code if appropriate).

  • Import enclosed TestBottomNav.zip to Android Studio and run
  • Click Dashboard or Notification item on BottomNavigationView.

• What happened.

There is no response after clicking tab item, meanwhile there is no related exception messages printed in Logcat.

This abnormal behaviour was intentional made on my part, just to amplify the problem. To fix it, go to app/src/main/res/menu/bottom_nav_menu.xml, change every android:id starts with Navigation to navigation will be fine.

• What you think the correct behavior should be.

NavigationUI should not ate the exception message with a simple false return. This will drive novice developers crazy to find out the problem. See here and here. We should not design API from the perspective of "everyone knows why", and it is also inconsistent with Google's strong advocacy of Jetpack for novice developers over these years.

• Is this a security related issue? Yes/No

No.
