DefaultLifecycleObserver

public interface DefaultLifecycleObserver extends LifecycleObserver

Known direct subclasses
AmbientLifecycleObserver

Interface for LifecycleObservers which are used to add ambient mode support to activities on Wearable devices.

Callback interface for listening to LifecycleOwner state changes. If a class implements both this interface and LifecycleEventObserver, then methods of DefaultLifecycleObserver will be called first, and then followed by the call of LifecycleEventObserver.onStateChanged

If a class implements this interface and in the same time uses OnLifecycleEvent, then annotations will be ignored.
