RxJava and Retrofit2: NetworkOnMainThreadException

Question

I realize that I am using subscribeOn()/observeOn() on the MainThread. What are the set of options I can pass into subscribeOn()? What are the set of options I can pass into

Answer 1

You should call Observable.unsubscribeOn(Schedulers.io()), retrofit will unsubscribe at the end of a http-request.

In RxJavaCallAdapterFactory of retrofit-rxjava-adapter

it actions like this.

if (!subscriber.isUnsubscribed()) {
    subscriber.onCompleted();
}

But when subscriber is a SafeSubscriber, it'll call unsubscribe finally.

I have this issue in my app.

Full code:

o.subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .unsubscribeOn(Schedulers.io());
