Firebase Cloud Messaging - Android Device not display notification but he receives it

Federico787878Federico787878 USMember ✭✭

Hi I'm trying to send notifications to an Android device.
I am using this plugin CrossGeeks/PushNotificationPlugin
I created the firebase project and extracted the parameters for use on web api that I made with .NET Core MVC 3.1
When I send the notification, the breakpoint on the event is triggered correctly

CrossPushNotification.Current.OnNotificationReceived + = (s, p) =>

However, no notification is displayed on my device.

If, on the other hand, I use the firebase console to send a notification, it appears correctly with both the inactive app and the foreground app.

For this reason, since my client application correctly receives notifications from firebase, I think the problem is server side.

This is my code:

    [HttpPost, Route("Prova")]
    public async Task<IActionResult> SendNotication()
            var notification = new GoogleNotification();
            notification.Data = new GoogleNotification.DataPayload();
            notification.Data.Title = "Title";
            notification.Data.Body = "bla bla";        

            using (var fcm = new FcmSender("xxxxxx", "yyyyy"))

                await fcm.SendAsync("hhhhhhh", notification);


            return Ok("Done");
        catch (Exception ex)
            return BadRequest(ex.Message);

     public class GoogleNotification
            public class DataPayload
                public string Title { get; set; }
                // Add your custom properties as needed
                public string Body { get; set; }

                public string Tag { get; set; }

            //public string Priority { get; set; } = "high";

            public DataPayload Data { get; set; }

I have doubts about the GoogleNotification class, do you think it is correct?
I tried through the chrome console to understand the json that generates the firebase console. in fact it is very different to my code

  "basics": {},
  "productAction": {
    "notificationAction": {
      "campaignId": "1581564767326567420",
      "messageText": "ciao",
      "campaignStatus": "STATUS_ENQUEUED",
      "displayParameters": {
        "title": "Titolo",
        "priority": "HIGH"
      "registrationIds": [
      "expiryTime": "2419200s",
      "lastUpdateTime": "2020-01-23T09:15:57.079Z"

this sent me into confusion, I found my code on the internet and thought it was working
