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

There is an error happening when you are trying to geocode the location.

Caused by: java.io.IOException: Timed out waiting for response from server at android.location.Geocoder.getFromLocation(Geocoder.java:136)

When you call subscribe with one Action1 as a parameter it only handles calls to onNext and if an error happens the app will crash.

You need to subscribe with:

subscribe(new Subscriber() {
    @Override
    public void onNext(Location location) { /*Handle the location updates*/ }

    @Override
    public void onCompleted() { }

    @Override
    public void onError(Throwable e) { }
})
