Android Navigation Architecture Component – Get current visible fragment

I managed to discover a way for now and it is as follows: NavHostFragment navHostFragment = supportFragmentManager.findFragmentById(R.id.nav_host); navHostFragment.getChildFragmentManager().getFragments().get(0); In case of course you know it is the first fragment. I am still investigating a way without this. I agree it is not the best way but that should be something for now.

Android Jetpack Navigation, BottomNavigationView with Youtube or Instagram like proper back navigation (fragment back stack)?

You don’t really need a ViewPager to work with BottomNavigation and the new Navigation architecture component. I have been working in a sample app that uses exactly the two, see here.
