Description

Welcome to my new Android course : ReactiveX in android , Android Development With RxJava/RxAndroid Masterclass.

RxJava is the Java implementation of Reactive Extensions. Everyone agrees that, It has become the single most important skill for professional level Android development over the years. We use RxJava with MVP, we user RxJava with MVVM, We use RxJava with Dagger, Retrofit and Room. RxJava is everywhere.

Reactive Extensions skill you get from this course can be easily applied with other programming languages as well.

I have been working as a Software Engineer since 2008. I have been teaching Android Development for many years now. I will share many tips and best practices I leant by working with RxJava and taching RxJava over the years.

By the end of this course, you will be able to fluently apply RxJava for your Android development projects.

RxJava created to make our lives easier. But unfortunately many developers found it very difficult to start with as a result of longer learning curve and unavailability of resources.Many developers spend three or four weeks to figure out Rxjava fundamentals and best practices.

This course has designed to save your valuable time and to spare the pain of self-studying.

The teaching approach I am presenting here have already been successfully tested with my local students. They were able to master RxJava within a very short period of time, so I believe my online students will also get the same results.

RxJava is a very marketable skill, which is in high demand in the industry today.Whether you are going to use Java or Kotlin for Android Development ReactiveX skill will be a big advantage for you.

This course is for experienced android developers. You will need at least 3 months of android development experience to start following this course. This course contains,

Fundamentals of ReactiveX,RxJava and RxAndroid .
Main operators of RxJava .
RxBinding
Backpreassure
RxJava Subjects.
Retrofit short tutorial
RxJava with Retrofit
Room DB short tutorial
RxJava with Room Database
Case study project examples
Downloadable code samples
Short Notes
Interview Questions
Multiple Choice Questions

I'm so confident that you'll love this course that we're offering a FULL money back guarantee for 30 days! So it's a complete no-brainer, sign up today with ZERO risk and EVERYTHING to gain.

So what are you waiting for? Click the buy now button and join the course . Let's start learning RxJava today.

Note:

During the course to demonstrate different usages of retrofit, we will use TMDB free online REST API . You may need to provide an email address to sign up and get a free API key from them.

Who this course is for:

Professional Android developers
Determined students who are willing to become professional Android developers
