It is not possible for the view of the NavHostFragment to be available in the onCreate() of the Activity. In this case, the NavHostFragment lifecycle method follows the Activity lifecycle methods directly therefore, when the activity is on onCreate() so is the NavHostFragment. However, if the Fragment Lifecycle was driven with a LifecycleObserver (https://issuetracker.google.com/issues/127528777 ), onCreate() could be dispatched for a Fragment separately from the onCreate() for an Activity (or a parent Fragment if using a child Fragment). This means that if you were using a LifecycleObserver, it would be possible for the views to be available when onCreate() is dispatched and findNavController() would work in the LifecycleObserver's onCreate().

Possible workaround #4: call findNavController in onPostCreate.
Description
Version used: 1.1.0-alpha09
Devices/Android versions reproduced on:
When using nested fragments such as:
Parent
-- Child
I'd expect the Lifecycle changes of these fragments to be properly nested:
Parent CREATED
Child CREATED
Parent STARTED
Child STARTED
Parent RESUMED
Child RESUMED
---
Child PAUSED
Parent PAUSED
Child STOPPED
Parent STOPPED
Child DESTROYED
Parent DESTROYED
But I'm not seeing that - it seems like the opposite is the case - the child gets changed first on the way up and after on the way down, perfectly *not* nesting.
