How to handle onError inside RxJava. I am getting “OnErrorNotImplementedException”

Question

In my app I am using ReactiveLocationProvider library (link). I subscribe for updates in the onCreate method. It works fine when the device is online but if I switch my wifi

Answer 1

If you still wish to implement only one method and handle error too, then probably you can have abstract CustomSubscriber like below.

public abstract class CustomSubscriber extends Subscriber {

    @Override
    public void onCompleted() {

    }

    @Override
    public void onError(Throwable e) {

    }

    @Override
    public void onNext(T t) {

    }
}

Implement this way

 getObservable()
    .subscribeOn(Schedulers.io())
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe(new CustomSubscriber>() {
        @Override
        public void onNext(List list) {

        }
    });

hope some one will benefited.
