blackberry - 读取google map 返回的JSON数据

Question

在我的应用程序中，我使用 BlackBerry API 来获取纬度和经度。我想通过创建 http 连接使用 Google map 进行反向地理编码。如何解析数据，然后读取特定元素，例如地址？

示例 URL:

http://maps.google.com/maps/geo?json&ll=9.6,73.7

给出响应:

{
  "name": "9.600000,76.760000",
  "Status": {
    "code": 200,
    "request": "geocode"
  },
  "Placemark": [ {
    "id": "p1",
    "address": "Kanjirappalli Elikkulam Rd, Kerala, India",
    "AddressDetails": {
   "Accuracy" : 6,
   "Country" : {
      "AdministrativeArea" : {
         "AdministrativeAreaName" : "Kerala",
         "SubAdministrativeArea" : {
            "SubAdministrativeAreaName" : "Kottayam",
            "Thoroughfare" : {
               "ThoroughfareName" : "Kanjirappalli Elikkulam Rd"
            }
         }
      },
      "CountryName" : "India",
      "CountryNameCode" : "IN"
   }
