Answer 1

Create a channel (I use this method in Application.clss to create the channel )

  public void initChannels(Context context) {
    if (Build.VERSION.SDK_INT < 26) {
        return;
    }
    NotificationManager notificationManager =
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    NotificationChannel channel = new NotificationChannel("default"/*CHANNEL ID*/,
            "CHANNEL_NAME",
            NotificationManager.IMPORTANCE_DEFAULT);
    channel.setDescription("Channel description");
    assert notificationManager != null;
    notificationManager.createNotificationChannel(channel);
}

And use this channel default while creating instance of NotificationCompat

 .... notificationBuilder = new NotificationCompat.Builder(this,"default") ....
