I have create a wcf service to send notification to my android application but its not working

What I have tried:

my wcf method is

public string SendNotification1(string serverApiKey, string senderId, string deviceId, string message)

                string result;
                var value = message;

                WebRequest tRequest = WebRequest.Create("");
                tRequest.Method = "post";
                tRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
                tRequest.Headers.Add(string.Format("Authorization: key={0}", serverApiKey));
                tRequest.Headers.Add(string.Format("Sender: id={0}", senderId));

                string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message="
                    + value + "&data.time=" + System.DateTime.Now.ToString() + "®istration_id=" + deviceId + "";

                Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
                tRequest.ContentLength = byteArray.Length;

                using (Stream dataStream = tRequest.GetRequestStream())
                    dataStream.Write(byteArray, 0, byteArray.Length);

                    using (WebResponse tResponse = tRequest.GetResponse())
                        using (Stream dataStreamResponse = tResponse.GetResponseStream())
                            using (StreamReader tReader = new StreamReader(dataStreamResponse))
                                String sResponseFromServer = tReader.ReadToEnd();

            return message;


my iService:

       [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, UriTemplate = "SendNotification?serverApiKey={serverApiKey}&senderId={senderId}&deviceId={deviceId}&message={message}")]

       string SendNotification1(string serverApiKey, string senderId, string deviceId, string message);

wen my android application start I use service to save device token

I send success full notification using PHP but I need it with wcf service
the php code is


	function send_notification ($tokens, $message)

		$url = '';
		$fields = array(
			 'registration_ids' => $tokens,
			 'data' => $message
			$headers = array(			
			'Authorization:key =mykeyyyyyyy',
			'Content-Type: application/json'
	   $ch = curl_init();
       curl_setopt($ch, CURLOPT_URL, $url);
       curl_setopt($ch, CURLOPT_POST, true);
       curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
       curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
       curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);  
       curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
       curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
       $result = curl_exec($ch);           
       if ($result === FALSE) {
           die('Curl failed: ' . curl_error($ch));
       return $result;

	$conn = mysqli_connect("localhost","root","","fcm2");

	$sql = " Select Token From users";

	$result = mysqli_query($conn,$sql);
	$tokens = array();

	if(mysqli_num_rows($result) > 0 ){

		while ($row = mysqli_fetch_assoc($result)) {
			$tokens[] = $row["Token"];


	$message = array("message" => "my message");
	$message_status = send_notification($tokens, $message);
	echo $message_status ;

I will recommend using Azure Notification Hubs. They provide a very good ways of managing and sending your push notifications to your devices, not just Android, but the platform supports Windows Phone, iOS etc.
