Question

I am trying to get the zip code of the users current location.I have a teditText in MyActivity which should get populated based on the zip code I get from this activity.

public class LocationActivity extends MyActivity {
    double LATITUDE;
    double LONGITUDE;

    Geocoder geocoder = new Geocoder(this, Locale.ENGLISH); 
    {
        try {
            List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);

            if(addresses != null) {
                Address returnedZip = addresses.get(0);
                StringBuilder currentZip = new StringBuilder("Address:\n");
                for(int i=0; i<returnedZip.getMaxAddressLineIndex(); i++) {
                    strcurrentZip.append(returnedZip.getPostalCode());
                }
                m_zip.setText(strcurrentZip.toString());
            }
            else {
                m_zip.setText("No zip returned!");
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            m_zip.setText("zip not found!");
        }
    }
}

I am not getting any response,the app logcat does not show any errors but the the editText field I want to populate remains blank.

Here …

XPath xpath = XPathFactory.newInstance().newXPath();
String expression = "//GeocodeResponse/result/address_component[type=\"postal_code\"]/long_name/text()";
InputSource inputSource = new InputSource("https://maps.googleapis.com/maps/api/geocode/xml?latlng="+VARIABLECONTAININGLATITUDE+","+VARIABLECONTAININGLONGITUDE+"&sensor=true");
String zipcode = (String) xpath.evaluate(expression, inputSource, XPathConstants.STRING);

where VARIABLECONTAININGLATITUDE and VARIABLECONTAININGLONGITUDE are latitudes and longitudes from GPS or whatever location provider you choose.

also you need permission internet in manifest and location permission in manifest
