找不到com.google.android.gsf包

我想使用新的谷歌云消息传递系统，但我有一些问题。

I am trying to use new Google Cloud Messaging system but I have some problems.

我看了入门文档和审查演示程序;在那之后我申请要求，我的应用程序，然后我创建了一个新的虚拟设备与API 16。

I read Getting Started document and reviewed demo app; after that I applied requirements to my application then I created a new virtual device with API 16.

但是，当我尝试注册我的设备GCM，它失败，因为这行：

But when I try to register my device to GCM, it fails because of this line:

GCMRegistrar.checkDevice(getApplicationContext()); 

在我的logcat看到这些错误：

In logcat I see these errors:

我又增加了gcm.jar到我的类路径;我不知道什么是错的。

I had added gcm.jar to my class path; I don't know what is wrong.
