Android C2DMRegister.25寄存器：http错误401

我试图在本教程中使用C2DM客户端：http://www.vogella.de/articles/AndroidCloudToDeviceMessaging/article.html

我为客户端使用的代码与教程代码略有不同：

我只更改了包名，我将两个包合并在一个包中，com.DemoC2DM，我更改了清单中的一些行，以使代码与新的和唯一的包一起工作，但可能我在清单更改行中做了一些错误，因为我在尝试向客户机获取注册ID时遇到了以下错误：

这是我舱单的代码：

您好，只需在清单文件中进行以下更改，然后尝试使用

 <!-- Only C2DM servers can send messages for the app. If permission is 
        not set - any other app can generate it -->
    <receiver android:name="com.google.android.c2dm.C2DMBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND">
        <!-- Receive the actual message -->
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="com.DemoC2DM" />
        </intent-filter>
        <!-- Receive the registration id -->
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
            <category android:name="com.DemoC2DM" />
        </intent-filter>
    </receiver>

我得到了异常如果我做了你的更改，我在我的问题底部添加了异常，请检查它。在你的项目中找不到com.google.android.c2dm.c2dm这个类，所以你得到了异常。在做了更改后，请清理你的项目一次，这样它将生成R.java文件，然后检查againi是否做了，我仍然收到同样的异常：01-16 14:12:53.156:ERROR/AndroidRuntime1645:Caused:java.lang.ClassNotFoundException:com.google.android.c2dm.C2DMBroadcastReceiver in loader dalvik.system.PathClassLoader[/data/app/com.DemoC2DM-1.apk]你能给我发邮件给我那个演示吗？我会检查一下，然后返回使用，您可以使用：import/general/existing projects-into-workspace将其导入eclipse。您必须先解压缩zip文件
