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
<fragment
class="
android:id="@+id/myFragmentId"
android:layout_width="0px"
android:layout_height="wrap_content"
android:layout_weight="1"
android:label="@string/example_fragment" />
FragmentContainerView should also support a class attribute.
