You could use a Subject.
A Subject is a sort of bridge or proxy that acts both as an Subscriber and as an Observable. Because it is a Subscriber, it can subscribe to one or more Observables, and because it is an Observable, it can pass through the items it observes by reemitting them, and it can also emit new items.
public class Events { public static PublishSubjectWhen you want to publish something
Events.myEvent.onNext(myObject);When you want to receive an event
Events.myEvent.subscribe (...);Edit
**Using Architecture Components LiveData is better because it handles the lifecycle of and activity or fragment and you don't have to worried about unsubscribe from events because it observe the ui components lifecycle.
MutableLiveDatawhen you want to publish something
event.postValue(myObject);When you want to receive and event
event.observe(lifeCycleOwner, (myObject)->...);
