How to get the full ZIP using GeocodeLocation on Android?

I'm using GPS to return the user's address. Everything works fine, however the returned ZIP code is in the American standard, with 5 digits. Does anyone know any library or any way to get the 8-digit Brazilian standard?

public static void getAddressFromLocation(final double latitude, final double longitude, final Context context, final Handler   handler)    
{
    Thread thread = new Thread() {
        @Override
        public void run() {
            Geocoder geocoder = new Geocoder(context, Locale.getDefault());
            String result = null;

            // String tudo[] = new String[0];
            try {
                List<Address> addressList = geocoder.getFromLocation(
                        latitude, longitude, 1);
                if (addressList != null && addressList.size() > 0) {
                    Address address = addressList.get(0);
                    StringBuilder sb = new StringBuilder();
                    for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
                        sb.append(address.getAddressLine(i)).append("\n");
                       // tudo[i] = address.getAddressLine(i).concat("\n");
                    }
                      sb.append(address.getAdminArea()).append("\n");
                      sb.append(address.getLocality()).append("\n");
                      sb.append(address.getPostalCode()).append("\n");

                    result = sb.toString();

                }
            }
        }
    }
}
