Lifecycle Awareness

[ueen]

Whats about the registering and unregistering, why cann't the @subscribe function be Lifecycle Aware, registering on Class creation and unregistering on destruction, would be really neat if this could be added :)

I guess you try writing your own LifecycleObserver.

EventBus/EventBus/src/org/greenrobot/eventbus/EventBusLifecycleObserver.java

Lines 9 to 29 in 6348f40

	public class EventBusLifecycleObserver implements LifecycleObserver {
	private final LifecycleOwner lifecycleOwner;
	private final EventBus eventBus;
	public EventBusLifecycleObserver(LifecycleOwner lifecycleOwner, EventBus eventBus) {
	this.lifecycleOwner = lifecycleOwner;
	this.eventBus = eventBus;
	}
	@OnLifecycleEvent(Event.ON_START)
	void start() {
	eventBus.register(lifecycleOwner);
	}
	@OnLifecycleEvent(Event.ON_STOP)
	void stop() {
	eventBus.unregister(lifecycleOwner);
	}
	}

Yea i resorted to LiveData, as I need to send an event from a background thread even if the app is not opend but after reopening the UI has to react to that event, I couldn't really achieve that with EventBus. LiveData isn't the cleanest solution for events, but it is extremely reliable. In my opinion this behavior would also greatly improve EventBus :)
