For android O, there's the need to create a Notification Channel like this:

private static void createNotificationChannel() {
   // Create the NotificationChannel, but only on API 26+ because
   // the NotificationChannel class is new and not in the support library
   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
       NotificationChannel channel = new NotificationChannel(CHANNEL_ID, >"BEACON_CHANNEL_NAME", NotificationManager.IMPORTANCE_HIGH);
       channel.setDescription("BEACON_CHANNEL_DESCRIPTION");
       // Register the channel with the system; you can't change the importance
       // or other notification behaviors after this
       NotificationManager notificationManager = >getContext().getSystemService(NotificationManager.class);
       if (notificationManager != null) {
           notificationManager.createNotificationChannel(channel);
       }
   }

}

Hey @ldimitroff

As I understand, you've found a solution for your problem. Indeed, you need to setup your notification object properly according to the OS version.
