Notification not displaying on android device. (Azure notification hub) - azure

Question

I'm trying do send a push notification to my android emulator. When the notification is sent, it receives the notification but does not display it.
I'm using this code to display it.
void SendNotification(string messageBody)
{
var intent = new Intent(this, typeof(MainActivity));
intent.AddFlags(ActivityFlags.ClearTop);
var pendingIntent = PendingIntent.GetActivity(this, 0, intent, PendingIntentFlags.OneShot);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.SetContentTitle("FCM Message")
.SetSmallIcon(Resource.Drawable.icon)
.SetContentText(messageBody)
.SetChannelId("my-chanel")
.SetAutoCancel(true)
.SetContentIntent(pendingIntent)
.SetSound();
var notificationManager = NotificationManager.FromContext(this);
notificationManager.Notify(0, notificationBuilder.Build());
}
But when the notification is received nothings happens and the logs of my devices gives me this:
[Mono] Assembly Ref addref ODEON.Android[0xa31db5c0] -> System.Core[0xa1f2f900]: 7
[MyFirebaseMsgService] From: 241571420247

[Notification] Use of stream types is deprecated for operations other than volume control
[Notification] See the documentation of setSound() for what to use instead with android.media.AudioAttributes to qualify your playback use case
Can anyone tell my why it doesn't display.
Thanks in advance!

If the send notification mehtod is called use the below code to show notifications:
var intent = new Intent(this, typeof(MainActivity));
intent.AddFlags(ActivityFlags.ClearTop);
var pendingIntent = PendingIntent.GetActivity(this, 0, intent, PendingIntentFlags.OneShot);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.SetSmallIcon(Resource.Drawable.ic_stat_ic_notification)
.SetContentTitle("Title")
.SetContentText(messageBody)
.SetAutoCancel(true)
.SetContentIntent(pendingIntent);
NotificationManagerCompat notificationManager = NotificationManagerCompat.From(this);
notificationManager.Notify(0, notificationBuilder.Build());
Also if you have Android V 8+ devices which I'm sure you will see to it you are registering for a notification channel in your MainActivity OnCreate method
void CreateNotificationChannel()
{
if (Build.VERSION.SdkInt < BuildVersionCodes.O)
{
// Notification channels are new in API 26 (and not a part of the
// support library). There is no need to create a notification
// channel on older versions of Android.
return;
}
var channel = new NotificationChannel(CHANNEL_ID, "FCM Notifications", NotificationImportance.Default)
{
Description = "Firebase Cloud Messages appear in this channel"
};
var notificationManager = (NotificationManager) GetSystemService(NotificationService);
notificationManager.CreateNotificationChannel(channel);
}
