How can I pass data to the first Fragment whilst using the Navigation Architecture?

I'm trying to pass a bundle of object instances down from my main activity to the first fragment in a chain of other fragments using the NavHostFragment. I've tried all sorts but the bundle always seems to be null once it reaches the first fragment.



Here's how I'm initiating the NavHostFragment (frameContainer is a Frame Container element in my layout xml)



NavHostFragment navHost = NavHostFragment.create(R.navigation.claim_nav_graph);

getSupportFragmentManager().beginTransaction()

        .replace(R.id.frameContainer, navHost)

        .setPrimaryNavigationFragment(navHost)

        .commit();


The documentation says there are 2 different .create functions, one of them you can pass a second arguments to as a bundle, but Android Studio doesn't allow me to use this version.



Does anyone have any ideas?



Thanks in advance!
