Question

I would like to know how to ignore exceptions and continue infinite stream (in my case stream of locations)?

Just pasting the link info from @MikeN's answer incase it gets lost:

import rx.Observable.Operator;
import rx.functions.Action1;

public final class OperatorSuppressError implements Operator {
    final Action1 onError;

    public OperatorSuppressError(Action1 onError) {
        this.onError = onError;
    }

    @Override
    public Subscriber call(final Subscriber t1) {
        return new Subscriber(t1) {

            @Override
            public void onNext(T t) {
                t1.onNext(t);
            }

            @Override
            public void onError(Throwable e) {
                onError.call(e);
            }

            @Override
            public void onCompleted() {
                t1.onCompleted();
            }

        };
    }
}

and use it close to the observable source because other operators may eagerly unsubscribe before that.

Observerable.create(connectToUnboundedStream()).lift(new OperatorSuppressError(log()).doOnNext(someStuff()).subscribe();

Note, however, that this suppresses the error delivery from the source. If any onNext in the chain after it throws an exception, it is still likely the source will be unsubscribed.
