Android c2dm未收到任何消息

我已经在我的手机应用程序上实现了c2dm。c2dm应用程序几天前确实接收到消息，但过了一段时间它就停止接收任何消息

当推到google c2dm链接时，我得到了响应“id=0:1325918022124320%6c25a09400000031”。在标题正确的情况下，这里是否有错误

我正在使用以下命令发送消息

   public void SendMessage(string registrationId, string data, string sAuth)
    {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://android.clients.google.com/c2dm/send");
        request.Method = "POST";
        request.KeepAlive = false;

        NameValueCollection postFieldNameValue = new NameValueCollection();
        postFieldNameValue.Add("registration_id", registrationId);
        postFieldNameValue.Add("collapse_key", "1");
        postFieldNameValue.Add("delay_while_idle", "0");
        postFieldNameValue.Add("data.payload", data);
        string postData = ConstructQueryString(postFieldNameValue);
        byte[] byteArray = Encoding.UTF8.GetBytes(postData);

        request.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
        request.ContentLength = byteArray.Length;

        request.Headers.Add(HttpRequestHeader.Authorization, "GoogleLogin auth=" + sAuth);

        Stream dataStream = request.GetRequestStream();
        dataStream.Write(byteArray, 0, byteArray.Length);
        dataStream.Close();

        WebResponse response = request.GetResponse();
        HttpStatusCode responseCode = ((HttpWebResponse)response).StatusCode;
        if (responseCode.Equals(HttpStatusCode.Unauthorized) || responseCode.Equals(HttpStatusCode.Forbidden))
        {
            Response.Write("Unauthorized - need new token");
        }
        else if (!responseCode.Equals(HttpStatusCode.OK))
        {
            Response.Write("Response from web service not OK :");
            Response.Write(((HttpWebResponse)response).StatusDescription);
        }

        StreamReader reader = new StreamReader(response.GetResponseStream());
        string responseLine = reader.ReadLine();
        reader.Close();
        Response.Write(responseLine); 

    }

用你的谷歌注册密钥检查两次。我想可能会有什么变化，那就是你不能接受任何按摩。确保服务器和客户端上的密钥相同

如果您有任何疑问，请进一步询问。我已尝试手动输入注册表项，但它仍然不起作用。我甚至重新启动了我的手机，用全新的gmail账号重新注册了注册器，然后用c2dm注册。之后，您将获得注册id，并将该id传递给服务器端代码以发送消息。我想你对密钥注册器设备有问题，比如发送电子邮件到服务器并从广播中取回“注册id”？ThanksInt registrationIntent=new Intent（“com.google.android.c2dm.Intent.REGISTER”）；registrationIntent.putExtra（“app”，PendingIntent.getBroadcast（this，0，new Intent（），0））；registrationIntent.putExtra（“发送方”xyz@gmail.com"); 此。startService（注册内容）；
