无法从公共google calendar api v3获取事件

Question

在本教程http://www.androidhive.info/2012/01/android-json-parsing-tutorial之后，我对它进行了修改，使用以下URL来解析一个公共google日历：“https://www.googleapis.com/calendar/v3/calendars/[calendar_ID]/events？singleevents=true&orderby=starttime&key=[my_API_key]”，而不是示例中的URL。这个日历是公开的。

当我执行应用程序时，响应如下：

{
 "error": {
  "errors": [
   {
    "domain": "usageLimits",
    "reason": "accessNotConfigured",
    "message": "Access Not Configured. The API is not enabled for your project, or there is a per-IP or per-Referer restriction configured on your API key and the request does not match these restrictions. Please use the Google Developers Console to update your configuration.",
    "extendedHelp": "https://console.developers.google.com"
   }
  ],
  "code": 403,
  "message": "Access Not Configured. The API is not enabled for your project, or there is a per-IP or per-Referer restriction configured on your API key and the request does not match these restrictions. Please use the Google Developers Console to update your configuration."
 }
}

问题出在哪里？我做错了什么？

最后我找到了解决办法。

在这个URL https://www.googleapis.com/calendar/v3/calendars/[calendar_ID]/events？singleevents=true&orderby=starttime&key=[my_API_key]中，我使用的是Android应用程序的API密钥。当我将此键改为浏览器的API键时，问题就消失了。
