Because the native library contains nested classes InternetObservingSettings > Builder that conflicting with binding InternetObservingSettings.binding static method that can't be registered as InternetObservingSettings.Binding. As a result, used another name is InvokeBuilder().

Using:

InternetObservingSettings settings = InternetObservingSettings.InvokeBuilder()
    .Interval(5000)
    .Build();

var obj = ReactiveNetwork
    .ObserveInternetConnectivity(settings)
    .SubscribeOn(Schedulers.Io())
    .Subscribe(_consumer);
