Part 2 — Understanding Flowables in RxJava

Learning RxJava shouldn’t be hard

Part 1 — Getting started with RxJava

Quick Intro

In RxJava basically there are two Observable object classes — Observable and Flowable. The difference between them is backpressure. Flowables are backpressure aware while Observables are not.
