About the gist

EDIT: This has become soon obsolete when Observable.fromAsync() has been released in RxJava. An issue from JakeWarthon here: ReactiveX/RxJava#4177 generated a pull request which is being implemented / discussed here: ReactiveX/RxJava#4179 . See below on how to use it.

I'm learning RxJava. Many Rx-libraries out there are using Obvservable.create() with an inline OnSubscribe implementation to wrap legacy APIs, like this one for the Android GoogleMap API:

class MapFragmentMapReadyOnSubscribe implements Observable.OnSubscribe<GoogleMap> {
  final MapFragment fragment;

public class Pager<I, O> {

    private static final Observable FINISH_SEQUENCE = Observable.never();

    private PublishSubject<Observable<I>> pages;
    private Observable<I> nextPage = finish();
    private Subscription subscription = Subscriptions.empty();

    private final PagingFunction<I> pagingFunction;
    private final Func1<I, O> pageTransformer;
