FabricUIManager

open class FabricUIManager : UIManager, LifecycleEventListener, UIBlockViewResolver, SynchronousEventReceiver

We instruct ProGuard not to strip out any fields or methods, because many of these methods are only called through the JNI from Cxx so it appears that most of this class is "unused".
