JAVA google geocoding API get city

Question

I'm trying to get the Country and City names from latitude and longtitude using google geocoding API. This library https://github.com/googlemaps/google-maps-services-java as a JAVA implementation for the API.

This is the current way i'm making it:

GeoApiContext context = new GeoApiContext().setApiKey("AI... my key");
GeocodingResult[] results =  GeocodingApi.newRequest(context)
        .latlng(new LatLng(40.714224, -73.961452)).language("en").resultType(AddressType.COUNTRY, AddressType.ADMINISTRATIVE_AREA_LEVEL_1).await();

logger.info("Results lengh: "+ results.length);

for(int i =0; i< results[0].addressComponents.length; i++) {
    logger.info("Address components "+i+": "+results[0].addressComponents[i].shortName);
}

The problem is: There is a 5 levels of AddressType.ADMINISTRATIVE_AREA_LEVEL_1 and city name is on different levels depends on specific location/country. So the question is - how can i extract exactly the city name from the results? or how do i need form a request properly ?

P.S. it is not a mobile app.

Use AddressComponentType.LOCALITY to get city name from GeocodingResult

I do it on this way:

private PlaceName parseResult(GeocodingResult r) {

    PlaceName placeName = new PlaceName(); // simple POJO

    for (AddressComponent ac : r.addressComponents) {
        for (AddressComponentType acType : ac.types) {

            if (acType == AddressComponentType.ADMINISTRATIVE_AREA_LEVEL_1) {

                placeName.setStateName(ac.longName);

            } else if (acType == AddressComponentType.LOCALITY) {

                placeName.setCityName(ac.longName);

            } else if (acType == AddressComponentType.COUNTRY) {

                placeName.setCountry(ac.longName);
            }
        }

        if(/* your condition */){ // got required data
            break;
        }
    }

    return placeName;
}
