interface DefaultLifecycleObserver : LifecycleObserver
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, the methods of DefaultLifecycleObserver are called first, followed by LifecycleEventObserver.onStateChanged.
Note: If a class implements this interface and also uses the deprecated androidx.lifecycle.OnLifecycleEvent annotations, those annotations are ignored.
