20. rx.Observable RXJAVA
21. rx.Observable RXJAVA reactivex.Observable reactivex.Flowable RXJAVA 2
22. reactivex.Observable RXJAVA 2 • ~1k elements • GUI & touch events • Synchronous flow
23. reactivex.Flowable RXJAVA 2 • 10k+ elements • Reading from file, databases and network • Blocking/pull-based data source
24. Single RXJAVA Completable
25. Single* RXJAVA 2 Completable Maybe * has been totally redesigned
26. Maybe RXJAVA 2 onSubscribe (onSuccess | onError | onComplete)?
27. BACKPRESSURE
28. Observable.from() RXJAVA
29. Observable.fromArray() RXJAVA 2 Observable.fromIterable() Observable.fromFuture()
30. Observable.create() RXJAVA
