Get country from coordinates?

Question

How to get country name in Android, If are known geo coordinates? How to make it the simplest way?

Answer 1

How I did it recently was to read the data from the Web API URL and parse the JSON.

An example URL for the point(40.714224, -73.961452) is:

http://maps.google.com/maps/geo?q=40.714224,-73.961452&output=json&oe=utf8&sensor=true_or_false&key=your_api_key

Which produces the following output:

{
  "name": "40.714224,-73.961452",
  "Status": {
    "code": 200,
    "request": "geocode"
  },
  "Placemark": [ {
    "id": "p1",
    "address": "285 Bedford Ave, Brooklyn, NY 11211, USA",
    "AddressDetails": {
   "Accuracy" : 8,
   "Country" : {
      "AdministrativeArea" : {
         "AdministrativeAreaName" : "NY",
         "SubAdministrativeArea" : {
            "Locality" : {
               "DependentLocality" : {
                  "DependentLocalityName" : "Williamsburg",
                  "PostalCode" : {
                     "PostalCodeNumber" : "11211"
                  },
                  "Thoroughfare" : {
                     "ThoroughfareName" : "285 Bedford Ave"
                  }
               },
               "LocalityName" : "Brooklyn"
            },
            "SubAdministrativeAreaName" : "Kings"
         }
      },
      "CountryName" : "USA",
      "CountryNameCode" : "US"
   }
},
    "ExtendedData": {
      "LatLonBox": {
        "north": 40.7154779,
        "south": 40.7127799,
        "east": -73.9600584,
        "west": -73.9627564
      }
    },
    "Point": {
      "coordinates": [ -73.9614074, 40.7141289, 0 ]
    }
  } ]
}

I find GSON to be quite good for parsing JSON in Android.
