below is my code: Private Sub send(ByVal regId As String) Dim tRequest As WebRequest tRequest = WebRequest.Create("https://android.googleapis.com/gcm/send") tRequest.Method = "post" tRequest.ContentType = " application/x-www-form-urlencoded;charset=UTF-8" tRequest.Headers.Add("Authorization: key=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") tRequest.Headers.Add("Sender: id=0000000000") Dim collaspeKey As String = Guid.NewGuid().ToString("n") Dim postData As String = "collapse_key=" & collaspeKey & "&data.payload=" & Convert.ToString(txtMsg.Text) & "&data.time=" & System.DateTime.Now.ToString() & "®istration_id=" & regId & "" Dim byteArray As [Byte]() = Encoding.UTF8.GetBytes(postData) tRequest.ContentLength = byteArray.Length Dim dataStream As Stream = tRequest.GetRequestStream() dataStream.Write(byteArray, 0, byteArray.Length) dataStream.Close() Dim tResponse As WebResponse = tRequest.GetResponse() dataStream = tResponse.GetResponseStream() Dim tReader As New StreamReader(dataStream) Dim sResponseFromServer As [String] = tReader.ReadToEnd() lblStat.Text = sResponseFromServer tReader.Close() dataStream.Close() tResponse.Close() End Sub *************************************************************************************************** on executing getresponse, google fires "The remote server returned an error: (401) Unauthorized" error.
