Messages on Toast and Logcat talk about you should be paid attention to 2 items and them order:

  1. NotificationChannel mChannel = new NotificationChannel(id, name, importance);
  2. builder = new NotificationCompat.Builder(this, id);

Also NotificationManager notifManager and NotificationChannel mChannel are created only once.

There are required setters for Notification:

builder.setContentTitle() // required  
       .setSmallIcon()    // required 
       .setContentText()  // required

See the example in On Android 8.1 API 27 notification does not display.
