Single Observable with Multiple Subscribers

Question

I have an Observable<> getFoo() that is created from a Retrofit Service and after calling the .getFoo() method, I need to

Answer 1

You seem to be (implicitly) casting your ConnectedObservable returned by .share() back into a normal Observable. You might want to read up on the difference between hot and cold observables.

Try

ConnectedObservable> testObservable = retrofit
        .create(GitHub.class)
        .contributors("square", "retrofit")
        .share();

Subscription subscription1 = testObservable
   .subscribe(new Subscriber>() {
    @Override
    public void onCompleted() {

    }

    @Override
    public void onError(Throwable throwable) {

    }

    @Override
    public void onNext(List contributors) {
        System.out.println(contributors);
    }
});

Subscription subscription2 = testObservable
        .subscribe(new Subscriber>() {
            @Override
            public void onCompleted() {

            }

            @Override
            public void onError(Throwable throwable) {

            }

            @Override
            public void onNext(List contributors) {
                System.out.println(contributors + " -> 2");
            }
        });

testObservable.connect();
subscription1.unsubscribe();
subscription2.unsubscribe();

Edit: You don't need to call connect() every time you want a new subscription you only need it to start up the observable. I suppose you could use replay() to make sure all subsequent subscribers get all items produced

ConnectedObservable> testObservable = retrofit
        .create(GitHub.class)
        .contributors("square", "retrofit")
        .share()
        .replay()
