问题是 ：

我打电话后

C2DMessaging.register(Context context,String senderId)

注册我的应用程序的方法。

但我在 C2DMBroadcastReceiver 的 onReceive() 中没有收到任何内容。

这是结构图。我不能在这里张贴图片。所以只需上传到盒子。

请帮助我。谢谢

清单文件中的问题

您必须在应用程序标签中写入服务和接收者标签

例如：

<application android:icon="@drawable/icon"
        android:label="@string/app_name">

<service
            android:name=".C2DMReceiver"
            android:enabled="true" />

<!--SAME FOR RECIEVER-->

</application>

还有一件事..你在写

<receiver
            android:name="com.google.android.c2dm.C2DMBroadcastReceiver"

您的文件夹结构是 com/google/android/c2dm/ 其中包含 C2DMBroadcastReceiver 类吗？
