    Request SingleObservable to start streaming data.

    Request SingleObservable to start streaming data.

    This is a "factory method" and can be called multiple times, each time starting a new Subscription. Each Subscription will work for only a single Observer.

    If the Observable rejects the subscription attempt or otherwise fails it will signal the error via Observer.onError.

    observer

    the Observer that will consume signals from this Observable
