Asynchronous Android Programming - Second Edition

RxJava setup

Before we move further, let's add the required libraries to your project. If you're using Android Studio, just add the following dependencies to the module build.gradle script:

dependencies {
    …
    compile 'io.reactivex:rxandroid:1.1.0'
    compile 'io.reactivex:rxjava:1.1.0'
}

rxjava is a library that implements the Reactive Extensions (http://reactivex.io/) on Java , and rxandroid is a library that adds classes to help write reactive components with RxJava in Android applications.
