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

Federico787878

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()
    {
        try
        {
            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
            {
                [JsonProperty("title")]
                public string Title { get; set; }
                // Add your custom properties as needed
                [JsonProperty("body")]
                public string Body { get; set; }

                [JsonProperty("tag")]
                public string Tag { get; set; }
            }

            //[JsonProperty("priority")]
            //public string Priority { get; set; } = "high";

            [JsonProperty("data")]
            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": [
        "dcdsdsffds"
      ],
      "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
