Question

我是Android编程的新手，并一直试图通过Android应用程序将事件添加到谷歌日历。我在网上找到了一个很好的例子但似乎无法让代码运行，因为一旦模拟器启动，应用程序就会崩溃。我正在模仿ANDROID DEVICE上的代码（Google API / API LEVEL 14）.Below是代码的URL;

以下是我在logcat中收到的错误;

Answer 1

这是：

android.database.sqlite.SQLiteException：没有这样的列：displayName：，同时编译：SELECT _id，displayName FROM Calendars

“日历”表中没有名称为“displayName”的列。

Answer 2

由于您使用的是ICS（SDK 14），因此他们改变了处理Calanders的方式并制作了公共API。见http://android-developers.blogspot.com/2011/10/ics-and-non-public-apis.html
