我通过将纬度和经度值传递给以下 URL 来获取街道、城市和国家/地区的详细信息：http://maps.google.com/maps/geo?q="+la+","+lo;. 但是，这突然停止工作，因为我现在得到返回的状态代码 610 而不是 200。我用谷歌搜索并发现 Google 已弃用 V3 版本的旧版本，建议使用更新到此版本。新的 URL 将是这样的；
http://maps.googleapis.com/maps/api/geocode/json?latlng=25.34041,-55.489864&sensor=false
但是，我完全迷失了如何使用这个？什么是 Google API 密钥？我应该从哪里获得这个。早些时候我使用上述 URL 并将以下内容导入到我的项目中：
import org.json.me.JSONArray;
import org.json.me.JSONObject;
请帮助如何进行此操作？
您正在请求正确的 URL，但您的 latlong 值可能无效。我请求网址：
http://maps.googleapis.com/maps/api/geocode/json?latlng=25.34041,-55.489864&sensor=false
结果。
{
"results" : [],
"status" : "ZERO_RESULTS"
}
使用不同的 latlong 但相同的 URL 请求：
http://maps.googleapis.com/maps/api/geocode/xml?latlng=51.962146,7.602304&sensor=false"
