Android GeoCoder: zip code search returns unexpected results

Question

I want to perform a search by entering user text using the GeoCoder class from Android. Here is my code:

Geocoder iGeocoder = new Geocoder(getContext(), Locale.GERMAN);

public Address getAdress(String aUserInput) {
    List<Address> tAddressList = iGeocoder.getFromLocationName(aUserInput, 1000, 47.060940, 8.564278, 51.526396, 13.736392);
    if(tAddressList != null &&
                tAddressList.size() > 0) {
        for(Address tAddress : tAddressList) {

            // return the first adress found for germany.
            Log.e(TAG, "returning Adress: " + tAddress );
            if(tAddress.getCountryCode().equals("DE")) {

                return tAddress;
            }

        }
        return null;
    } else {
        return null;
    }
}

The restrictive box that I pass in getFromLocationNameroughly represents the German state of Bavaria. I know that this bounding box does not guarantee that the resulting address really exists. I found some problems, especially when searching by zip code.

• Some of the resulting addresses returned when searching by zip code do not have an "admin zone", so I cannot filter for my desired state (= "Bavaria").

locale. . Germany .

Locale locale = new Locale(langCode, countryCode) 

Locale locale = new Locale("de", "DE");

Geocoder iGeocoder = new Geocoder(getContext(), locale);

                return tAddress;
