ZipCode from location

I need to find zip code for current location. Is this possible?

Answer 1

You can do it with Google’s Geocoding API. What you’re actually looking for is reverse-geocoding, but it supports that too. You can have it return XML and then parse it for the postal code (a.k.a zipcode). Should be quite simple actually.

To use the API, simply access it by HTTP with the correct latitude and longitude:

https://maps.googleapis.com/maps/api/geocode/xml?latlng=37.775,-122.4183333&sensor=true

Then parse the XML using XPath, or your favorite XML parser (or just use JSON):

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=37.775,-122.4183333&sensor=true");
String zipcode = (String) xpath.evaluate(expression, inputSource, XPathConstants.STRING);

I haven’t actually tested this bit of code (and it obviously needs exception handling), but I trust you’ll be able to get it working from here.

As for getting the location itself, this previous question sums it up nicely:
