Exploring RxJava 2 for Android
summary
RxJava 2 reworks Observable creation, subscription management and backpressure: it introduces Observable vs Flowable to mark whether a source supports backpressure, adds Single/Maybe/Completable for scalar or void results, and standardizes on disposable/subscription semantics with onSubscribe. Examples show using fromCallable and create with emitters to wrap sync and async calls, composing with map/flatMap/subscribeOn/observeOn, and claims measurable allocation and GC reductions; library is in dev preview with a final release imminent.
