無法從公共Google日曆API v3中獲取事件

Question

按照本教程http://www.androidhive.info/2012/01/android-json-parsing-tutorial我已將其調整爲使用此URL「https://www.googleapis.com/calendar/v3/calendars/[calendar_ID]/events?singleEvents=true&orderBy=startTime&key=[my_API_key]」解析公共Google日曆，而不是示例中的URL。這個日曆是公開的。

當我執行應用程序，響應是這樣的：

{ 
"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." 
} 
} 

問題出在哪裏？我做錯了什麼？

最後我找到了解決方案。

在此URL中https://www.googleapis.com/calendar/v3/calendars/[calendar_ID]/events?singleEvents=true&orderBy=startTime&key=[my_API_key]我使用的是Android應用程序的API密鑰。當我爲瀏覽器的API密鑰更改此密鑰時，問題消失。
