In order to send a notification from an Console App to an android device I am using the following code:
class Program
{
static void Main(string[] args)
{
string applicationId = "applicationId";
string senderId = "senderId";
string deviceId = "deviceId";
string message = "TestMessage";
var x = new AndroidFCMPushNotificationStatus();
var response = x.SendNotification(applicationId, senderId, deviceId, message);
Console.WriteLine(response);
Console.ReadLine();
}
}
and
public class AndroidFCMPushNotificationStatus
{
public string SendNotification(string applicationID, string senderId, string deviceId, string message)
{
try
{
WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
tRequest.Method = "post";
tRequest.ContentType = "application/json";
var data = new
{
to = deviceId,
notification = new
{
body = message,
title = message,
},
priority = "high"
};
var serializer = new JavaScriptSerializer();
var json = serializer.Serialize(data);
Byte[] byteArray = Encoding.UTF8.GetBytes(json);
tRequest.Headers.Add(string.Format("Authorization: key={0}", applicationID));
tRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
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 (sResponseFromServer);
}
}
}
}
catch (Exception ex)
{
return (ex.Message);
}
}
}
from Push Notification C#.
I created a firebase console project and from the project settings, from the tab Cloud Messaging I got the Server Key and Sender Id (in code they are the applicationId and senderId). I also got my device Id from an app I downloaded to my mobile, where it gives me a string under the label Android Device Id.
However I get the message error:InvalidRegistration.
I am pretty new to this and I think I am missing something.
- Is the above code supposed to work and whenever I run the program I should get a notification on my phone?
- Should I do anything to allow this notifications to my mobile? I haven't configured anything on my device.
- The idea is to pack this code in a service and whenever something is happening on the server I want to use this code in order to inform my device. Is this the correct way?
Thank you in advance.
