PublishRelay is a wrapper for PublishSubject, and BehaviorRelay is a wrapper for BehaviorSubject. You usually apply one or the other, but not both at the same time because publish ().replay () has no practical difference to a plain replay () and replay ().publish () is just a recipe for late consumers to not see the whole sequence.

Since it's an Observer, it can subscribe to one or more Observables and receive events from them. That engineers face when trying publishrelay vs behaviorrelay rxjava integrate RxJava + networking into an. This article is all about the Subject available in RxJava. However, they are stateful in a damaging way: when they receive an onComplete or onError they no longer become 13 Activity. You usually apply one or the other, but not both at the same time because publish ().replay () has no practical difference to a plain replay () and replay ().publish () is just a recipe for late consumers to not see the whole sequence. Also, given it's at the same time an Observable, it can reemit events or emit new events to its subscribers. WebLorem ipsum dolor sit amet, consectetur adipis cing elit.
