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

emits the value returned by the supplied function

returns an `Observable` in the supplied function

Upon subscription, the `Observable` created using `.defer()`______.

Upon subscription, the <code>Observable</code> created using <code>.defer()</code>______.

**(True or False)** An `Observable` emits items asynchronously by default.

Which of the following methods is called when an item is emitted by an `Observable`?

Which of the following methods is called when an item is emitted by an <code>Observable</code>?

**(True or False)** A hot `Observable` is subscriber-dependent.

(True or False) A hot <code>Observable</code> is subscriber-dependent.

It emits items regardless of whether there are any subscribers.

It never invokes any of an `Observer`'s method when subscribed to.

It emits items only when `.subscribe()` is invoked.
