Replace your code with this

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                /* Create or update. */
        NotificationChannel channel = new NotificationChannel("channel_01",
                "Playback Notification",
                NotificationManager.IMPORTANCE_LOW);
        channel.setSound(null, null);
        mNotificationManager.createNotificationChannel(channel);
        mBuilder.setChannelId("channel_01");
    }
