Using FragmentContainerView with Navigation component?

Question

After updating to Navigation 2.2.0-beta01 from the previous version, lint gives a warning about replacing the tag with FragmentContainerView<

Answer 1

There is still a bug that will thrown an exception if you simply replace fragment for . The fix, as of now, as stated by many google enginners in this bug thread is to change your code in your activity:

val navHostFragment = supportFragmentManager.findFragmentById(R.id.my_nav_host_fragment) as NavHostFragment
val navController = navHostFragment.navController
