我尝试使用Google GCM发送推送通知.但得到一个WebException,说远程服务器返回401 unautorized.我无法理解为什么它不起作用.

有谁知道它为什么不起作用？

这是我的代码:

            ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(ValidateServerCertificate);

           HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("https://android.googleapis.com/gcm/send");


            Request.Method = "POST";
            Request.KeepAlive = false;

            string postData = "{ 'registration_ids': [ '"+registrationId+"' ], 'data': {'message': '"+message+"'}}";

            byte[] byteArray = Encoding.UTF8.GetBytes(postData);

            Request.ContentType = "application/json";
            //Request.ContentLength = byteArray.Length;


            //Request.Headers.Add(HttpRequestHeader.Authorization, "GoogleLogin auth=" + AuthString);
            Request.Headers.Add(HttpRequestHeader.Authorization, "Authorization: key=AIzaSyCEygavdzrNM3pWNPtvaJXpvW66CKnjH_Y");
            //-- Delegate Modeling to Validate Server Certificate --//


            //-- Create Stream to Write Byte Array --// 
            Stream dataStream = Request.GetRequestStream();
            dataStream.Write(byteArray, 0, byteArray.Length);
            dataStream.Close();

            //-- Post a Message --//
            WebResponse Response = …

我试图在我的Android应用程序中使用C2DM,但在我添加它之后我无法安装该应用程序.我收到此错误"安装错误:INSTALL_PARSE_FAILED_MANIFEST_MALFORMED".但我看不出什么是错的.

谁知道我做错了什么？
