大家好，我正在开发一个应用程序，它将所有事件从谷歌日历下载到安卓设备。我找到了这个例子： http ://code.google.com/p/google-api-java-client/source/browse/calendar-android-sample/?repo=samples
我还从http://code.google.com/p/google-api-java-client/wiki/APIs下载了所需的库 也从这里：“http://code.google.com/p/google-api -java-客户端/下载/列表"
但是我收到错误，因为找不到类定义。请帮我。我的Logcat如下：
