A Complete Guide To Learn RxJava

A Complete Resources and Tutorials To Learn RxJava At One Place.

What is RxJava?

RxJava is used for reactive programming. In reactive programming, the consumer reacts to the data as it comes in. Reactive programming allows for event changes to propagate to registered observers.

As we know that the RxJava is the most important library for Android Projects. So we must have a proper grip on using RxJava in the Android Projects.


And I believe:

RxJava is an art and endless possibilities await those who can master it.

Let’s see all the best resources available to learn RxJava in the best possible way.

Complete RxJava Tutorial

RxJava is a Java VM implementation of Reactive Extensions. It has become the single most important skill for Android development.

Understanding RxJava Zip Operator With Example

Zip operator allows us to get the results from multiple observables at a time.This operator helps you to run all the tasks in parallel and returns the results of all the tasks in a single callback when all the tasks are completed.

Learn “How to implement caching using RxJava Operators”

Caching is very useful in the following situations:

  • Reduce network calls: We can reduce the network calls by caching the network response.
  • Fetch the data very fast: We can fetch the data very fast if it is cached.

Let’s learn how to implement caching in Android using the following RxJava Operators:

  • Concat Operator
  • FirstElement Operator

Implement Search Using RxJava Operators

Nowadays, most of the applications that we use in our daily life come with a search feature which provides us a facility to get things very quickly we are looking for. So, having a search feature is very important. And, we as a developer have a responsibility to implement it in a better way.The solution uses the following operators:

  • Filter Operator
  • Debounce Operator
  • DistinctUntilChanged Operator
  • SwitchMap Operator

We will learn all the above four RxJava Operators.Learn from here.
