无法在 Android 应用程序中集成 Google Calendar API

【问题标题】：Unable to integrate Google Calendar API in Android app无法在 Android 应用程序中集成 Google Calendar API
【发布时间】：2011-06-14 00:50:24
【问题描述】：

几天来，我一直在尝试将 Google 日历集成到我的 Android 应用中，但收效甚微。我已经实现了 GData API，并将他们提供的代码用于测试目的，但不断收到 SAXParser 错误，如下所示。我需要做的就是在用户的日历中创建新事件。

我用来添加事件的代码是：

void addToCalendar() throws IOException, ServiceException
    {
        CalendarService myService = new CalendarService("exampleCo-exampleApp-1");
        myService.setUserCredentials("<username>@gmail.com", "<password>");

    URL postUrl =
          new URL("https://www.google.com/calendar/feeds/<username>@gmail.com/private/full");
        CalendarEventEntry myEntry = new CalendarEventEntry();

        myEntry.setTitle(new PlainTextConstruct("Tennis with Beth"));
        myEntry.setContent(new PlainTextConstruct("Meet for a quick lesson."));

        DateTime startTime = DateTime.parseDateTime("2011-01-26T15:00:00+05:30");
        DateTime endTime = DateTime.parseDateTime("2011-01-26T15:12:00+05:30");
        When eventTimes = new When();
        eventTimes.setStartTime(startTime);
        eventTimes.setEndTime(endTime);
        myEntry.addTime(eventTimes);

        // Send the request and receive the response:
        CalendarEventEntry insertedEntry = myService.insert(postUrl, myEntry);
}

知道是什么导致了问题吗？另外，如果有人运行了日历 API，他们可以提供一些帮助吗？就像我说的，我只需要添加事件（单次和重复）

谢谢！

    【解决方案1】：

    你可以使用 GoogleApiJavaClient 看看这里为什么： http://code.google.com/p/gdata-java-client/wiki/MigratingToGoogleApiJavaClient

    在这里查看更多资源 http://code.google.com/p/google-api-java-client/

      【解决方案2】：

      GData API 无法在您的 android 上运行，请使用 google api 客户端，从此处：http://code.google.com/p/google-api-java-client/wiki/Android。

      见：Best option for using the GData APIs on Android?

      【讨论】：

      • 虽然我读过这篇文章，但我发现比任何事情都更奇怪的是 GData 现在可以完美地为我的应用程序工作（至少是日历位）。正如您在日志中看到的，我收到的只是警告。该功能本身运行流畅，只有一个小的 UI 错误意味着我看不到最终产品。
