Android OkHttp with Basic Authentication

Question

I'm using the OkHttp library for a new project and am impressed with its ease of use. I now have a need to use Basic Authentication. Unfortunately, there is a dearth of working sample code. I'm seeking an example of how to pass username / password credentials to the OkAuthenticator when an HTTP 401 header is encountered. I viewed this answer:

Retrofit POST request w/ Basic HTTP Authentication: "Cannot retry streamed HTTP body"

but it didn't get me too far. The samples on the OkHttp github repo didn't feature an authentication-based sample either. Does anyone have a gist or other code sample to get me pointed in the right direction? Thanks for your assistance!

Update Code for okhttp3:

import okhttp3.Authenticator;
import okhttp3.Credentials;
import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
import okhttp3.Route;

public class NetworkUtil {

private final OkHttpClient.Builder client;

{
    client = new OkHttpClient.Builder();
    client.authenticator(new Authenticator() {
        @Override
        public Request authenticate(Route route, Response response) throws IOException {
            if (responseCount(response) >= 3) {
                return null; // If we've failed 3 times, give up. - in real life, never give up!!
            }
            String credential = Credentials.basic("name", "password");
            return response.request().newBuilder().header("Authorization", credential).build();
        }
    });
    client.connectTimeout(10, TimeUnit.SECONDS);
    client.writeTimeout(10, TimeUnit.SECONDS);
    client.readTimeout(30, TimeUnit.SECONDS);
}

private int responseCount(Response response) {
    int result = 1;
    while ((response = response.priorResponse()) != null) {
        result++;
    }
    return result;
}

}
