RxJava

Since its inception in 2012, RxJava has slowly gained in popularity for enabling reactive programming on Android. It is now deemed as the go-to and leading reactive library. Many companies have adopted the reactive way of programming, including Google, with its release of Android Architecture Components, which has many reactive elements in its design.

In this course, you will learn the fundamental principles of RxJava which will serve as a foundation for experienced Android developers who are new to the library and want to start integrating it into their apps.

Reactive Programming with RxJava

# The origin
On October 28, 2005, Microsoft CTO, Ray Ozzie, wrote a 5000-word internal memo titled “The Internet Services Disruption.” The memo stressed to every department at Microsoft that they needed to adapt to the new Internet services era. With big players in the field like Google, Facebook, and Amazon, they needed to move fast. 


Erik Meijer and the Cloud Programmability Team at Microsoft heeded that call. They were determined to alleviate the complexity that plagued these large systems and killed developer productivity. The team decided to work on a programming model that could be utilized for these data-intensive internet services.


The breakthrough occurred when they realized that by dualizing the Iterable interface from the Gang of Four’s Iterator pattern, they would have a nice push-based model for easily dealing with asynchronous data streams. Over the course of the next couple of years, they would refine this idea and create Rx.
.Net (Reactive Extensions for .NET).





Rx$.$NET defined the set of interfaces—for example, `IObservable`, `IObserver`—that would be fundamental to reactive programming. Along with these came a toolbox of APIs for manipulating data streams such as mapping, filtering, selecting, transforming, and combining. Data streams had achieved first-class status with Rx$.$NET.
