Android GCM缺少注册C＃

Question

I'm trying to implement a push notification using the Google GCM, but, when I try to send a notification to GCM I'm getting the MissingRegistration error.

I'm using fake registration ids so far but I think that something like 'Registration not found' is raised in this case, right?

Here my C# piece of code

    public static void send(List<String> clientRegistrationIds, GcmData data)
    {
        WebRequest request = WebRequest.Create(SEND_URL);

        // Headers.
        request.Method = POST;
        request.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
        request.Headers.Add(string.Format("Authorization: key={0}", API_KEY));
        request.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));

        string postData = new JavaScriptSerializer().Serialize(new GcmRequest(clientRegistrationIds, data));
        Console.WriteLine(postData);

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

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

        WebResponse tResponse = request.GetResponse();

        dataStream = tResponse.GetResponseStream();

        StreamReader tReader = new StreamReader(dataStream);

        String sResponseFromServer = tReader.ReadToEnd();
        Console.WriteLine(sResponseFromServer);

        tReader.Close();
        dataStream.Close();
        tResponse.Close();
    }

The serialized postData variable:

{"registration_ids":["123"],"data":{"message":"New request!"}}

My response:

Error=MissingRegistration

What I'm doing wrong?

Thanks!

EDIT: Changing the content-type to application/json worked. Now i'm getting the error that I was expecting: InvalidRegistration . BUT, application/x-www-form-urlencoded;charset=UTF-8 wasn't supposed to be the correct Content-Type?

将ContentType更改为application/json并起作用。
