Make two API calls and update in one event

Observable.combineLatest(
    Api.getService(Api.getEndpointUrl()).getUserProfile(SoundcloudConstants.USERNAME),
    Api.getService(Api.getEndpointUrl()).getFavoriteTracks(SoundcloudConstants.USERNAME),
    new Func2<UserProfile, List<Track>, Account>() {
        @Override
        public Account call(UserProfile userProfile, List<Track> tracks) {
            return new Account(userProfile, tracks);
        }

• Functional Programming is a model of programming that transform and compose stream of immutable sequences by applying map, filter and reduce. Events are immutable because you can't change history.
• Reactive Programming is a model of programming focuses on data flow and change propagation.
• ReactiveX is an API that focuses on asynchronous composition and manipulation of observable streams of data or events by using a combination of the Observer pattern, Iterator pattern, and features of Functional Programming.
• RxJava is the open-source implementation of ReactiveX in Java.
• RxJava is a Java VM implementation of ReactiveX (Reactive Extensions): a library for composing asynchronous and event-based programs by using observable sequences.
• RxAndroid is a lightweight extension to RxJava that providers a Scheduler for Android’s Main Thread, as well as the ability to create a Scheduler that runs on any given Android Handler class.
• The two main classes are Observable and Subscriber.

• CacheControl.FORCE_CACHE adds an only-if-cache flag and also sets the max-stale to a very high value which overrides the max-stale value.
• The max-age request directive indicates that the client is unwilling to accept a response whose age is greater than the specified number of seconds. Unless the max-stale request directive is also present, the client is not willing to accept a stale response.
• The max-stale request directive indicates that the client is willing to accept a response that has exceeded its freshness lifetime. If max-stale is assigned a value, then the client is willing to accept a response that has exceeded its freshness lifetime by no more than the specified number of seconds.
• The max-age request directive is the oldest that a response can be, as long as the Cache-Control from the origin server indicates that it is still fresh. The max-stale request directive indicates that, even if the response is known to be stale, you will also accept it as long as it's only stale by
