Learning RxJava

By: Nield

Overview of this book

RxJava is a library for composing asynchronous and event-based programs using Observable sequences for the JVM, allowing developers to build robust applications in less time. Learning RxJava addresses all the fundamentals of reactive programming to help readers write reactive code, as well as teach them an effective approach to designing and implementing reactive libraries and applications. Starting with a brief introduction to reactive programming concepts, there is an overview of Observables and Observers, the core components of RxJava, and how to combine different streams of data and events together. You will also learn simpler ways to achieve concurrency and remain highly performant, with no need for synchronization. Later on, we will leverage backpressure and other strategies to cope with rapidly-producing sources to prevent bottlenecks in your application. After covering custom operators, testing, and debugging, the book dives into hands-on examples using RxJava on Android as well as Kotlin.

Summary

In this chapter, we touched on various parts of the rich RxAndroid ecosystem to build reactive Android applications. We covered Retrolambda so we can leverage lambdas with earlier versions of Android that only support Java 6. This way, we do not have to resort to anonymous inner classes to express our RxJava operators. We also touched on RxAndroid, which is the core of the reactive Android ecosystem, and it only contains Android Schedulers. To plug in your various Android widgets, controls, and domain-specific events, you will need to rely on other libraries, such as RxBinding.

In the next chapter, we will cover using RxJava with Kotlin. We will learn how to use this exciting new language, which has essentially become the Swift of Android, and why it works so well with RxJava.
