A Practical Guide To master Rx Streams
summary
Capital One Wallet runs a reactive MVVM on RxJava 2 and replaces callbacks with Singles, fromCallable and Single.create to model API and heavy work; concurrency uses subscribeOn/observeOn and schedulers; common operators are flatMap, switchMap, concat, zip, debounce, startWith and distinctUntilChanged; state flows use PublishRelay for events and BehaviorRelay to hold the last view state, driven by CompositeDisposable with clear vs dispose. Result: fewer bugs, easier testing and predictable UI updates.
