Class SingleLiveEvent

  • 
public final class SingleLiveEvent<T extends Object>
extends MutableLiveData<T>

    A lifecycle-aware observable that sends only new updates after subscription, used for events like navigation and Snackbar messages.

    This avoids a common problem with events: on configuration change (like rotation) an update can be emitted if the observer is active. This LiveData only calls the observable if there's an explicit call to setValue() or call().

    Note that only one observer is going to be notified of changes.

      final Unit call() Used for cases where T is Void, to make calls cleaner.
