我通过将latitde和经度值传递到以下网址来获取街道，城市和国家/地区详细信息：http://maps.google.com/maps/geo?q="+la+","+lo;。然而，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googled并且我发现谷歌已经弃用版本V3的旧版本，推荐使用是更新到此版本。新的URL将是这样的;
http://maps.googleapis.com/maps/api/geocode/json?latlng=25.34041,-55.489864&sensor=false
然而，我完全迷失了如何使用它？什么是Google API密钥？我应该从哪里获得这个。之前我使用上面提到的URL并将以下内容导入我的项目：
import org.json.me.JSONArray;
import org.json.me.JSONObject;
请帮忙解决这个问题？

您正在请求正确的网址，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"
}
请求不同的latlong但相同的网址：
