RxAndroid: Reactive Extensions for Android

Android specific bindings for RxJava 2.

This module adds the minimum classes to RxJava that make writing reactive components in Android applications easy and hassle-free. More specifically, it provides a Scheduler that schedules on the main thread or any given Looper.

Communication

Since RxAndroid is part of the RxJava family the communication channels are similar:

Binaries

ementation 'io.reactivex.rxjava2:rxandroid:2.0.2'
ecause RxAndroid releases are few and far between, it is recommended you also
xplicitly depend on RxJava's latest version for bug fixes and new features.
see https://github.com/ReactiveX/RxJava/releases for latest 2.x.x version)
ementation 'io.reactivex.rxjava2:rxjava:2.x.x'

Additional binaries and dependency information for can be found at http://search.maven.org.

Build

To build:

t clone git@github.com:ReactiveX/RxAndroid.git
 RxAndroid/
gradlew build

Further details on building can be found on the RxJava Getting Started page of the wiki.

Sample usage

A sample project which provides runnable code examples that demonstrate uses of the classes in this project is available in the sample-app/ folder.

Observing on the main thread

One of the most common operations when dealing with asynchronous tasks on Android is to observe the task's result or outcome on the main thread. Using vanilla Android, this would typically be accomplished with an AsyncTask. With RxJava instead you would declare your Observable to be observed on the main thread:

rvable.just("one", "two", "three", "four", "five")
    .subscribeOn(Schedulers.newThread())
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe(/* an Observer */);

This will execute the Observable on a new thread, and emit results through onNext on the main thread.

Observing on arbitrary loopers

The previous sample is merely a specialization of a more general concept: binding asynchronous communication to an Android message loop, or Looper. In order to observe an Observable on an arbitrary Looper, create an associated Scheduler by calling AndroidSchedulers.from:

er backgroundLooper = // ...
rvable.just("one", "two", "three", "four", "five")
    .observeOn(AndroidSchedulers.from(backgroundLooper))
    .subscribe(/* an Observer */)

This will execute the Observable on a new thread and emit results through onNext on whatever thread is running backgroundLooper.
