LifecycleEventObserver
public
interface
LifecycleEventObserver
implements
LifecycleObserver
androidx.lifecycle.LifecycleEventObserver |
Class that can receive any lifecycle change and dispatch it to the receiver.
If a class implements both this interface and
DefaultLifecycleObserver
, then
methods of DefaultLifecycleObserver
will be called first, and then followed by the call
of onStateChanged(LifecycleOwner, Lifecycle.Event)
If a class implements this interface and in the same time uses OnLifecycleEvent
, then
annotations will be ignored.
