How to get postal code using user current location in android

Question

I am trying to get postal code, but I am unable to get zipcode(postalcode). I can able to get current city but when I try to get the zipcode it's giving me a null pointer exception. Can anyone help me.

final Geocoder gcd = new Geocoder(getApplicationContext(),
                Locale.getDefault());

List<Address> addresses = gcd.getFromLocation(latitude, longitude, 1);
if (addresses.size() > 0)                                   Log.d(addresses.get(0).getLocality()); // I can get city name here.
Log.d(addresses.get(0).getPostalCode();// here i am getting nullpoiter exception

Answer 1

Try to use android built-in Geocoder to get details from latitude and longitude without calling google location api as below :

Initialize Gecoder using Context :

final Geocoder gcd = new Geocoder(context);

Get Address as result from Lat-Long, Here (10) max result.

List<Address> addresses = gcd.getFromLocation(latitude, longitude, 10);

Iterate to result get required location details :

for (Address address : addresses) {
    if(address.getLocality()!=null && address.getPostalCode()!=null){
        Log.d(address.getLocality());
        Log.d(address.getPostalCode();
       break;
    }
}

    Geocoder geocoder = new Geocoder(this, Locale.ENGLISH);
    List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);
    Address address=null;
    String addr="";
    String zipcode="";
    String city="";
    String state="";
    if (addresses != null && addresses.size() > 0){

            addr=addresses.get(0).getAddressLine(0)+"," +addresses.get(0).getSubAdminArea();
                 city=addresses.get(0).getLocality();
                 state=addresses.get(0).getAdminArea();

                 for(int i=0 ;i<addresses.size();i++){
                     address = addresses.get(i);
                     if(address.getPostalCode()!=null){
                         zipcode=address.getPostalCode();
                         break;
                     }

                }

I Used google webservice to get the zipcode.

The following is the google web service

http://maps.googleapis.com/maps/api/geocode/json?latlng=lattitude,longitude&sensor=true

here lattitude and longitude. so replace those values and you will get response and parse them and get postal code.
