Protected methods

createEntranceTransition

protected @NonNull Object createEntranceTransition()

Create entrance transition. Subclass can override to load transition from resource or construct manually. Typically app does not need to override the default transition that browse and details provides.

runEntranceTransition

protected void runEntranceTransition(@Nullable Object entranceTransition)

Run entrance transition. Subclass may use TransitionManager to perform go(Scene) or beginDelayedTransition(). App should not override the default implementation of browse and details fragment.
