I am running Android Oreo 8.1 in google pixel.

Fixed changed the goForeground method by:

private NotificationManager manager;

private NotificationManager getManager() {
        if (manager == null) {
            manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        }
        return manager;
}

private void goForeground() {
        Intent notificationIntent = new Intent(this, MainActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
            notificationIntent, 0);

        Notification n;
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            NotificationChannel chan1 = new NotificationChannel("default",
                    "default", NotificationManager.IMPORTANCE_DEFAULT);

            chan1.setLightColor(Color.GREEN);
            chan1.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
            getManager().createNotificationChannel(chan1);

            n = new Notification.Builder(this, chan1.getId())
                    .setContentTitle("Advertising device via Bluetooth")
                    .setContentText("This device is discoverable to others nearby.")
                    .setSmallIcon(R.drawable.ic_launcher)
                    .setContentIntent(pendingIntent)
                    .build();

        } else {
            n = new Notification.Builder(this)
                    .setContentTitle("Advertising device via Bluetooth")
                    .setContentText("This device is discoverable to others nearby.")
                    .setSmallIcon(R.drawable.ic_launcher)
                    .setContentIntent(pendingIntent)
                    .build();
        }

        startForeground(FOREGROUND_NOTIFICATION_ID, n);
    }

Thanks for the answer, but can you post your getManager()?

[agustinsivoplas]

Sorry, my bad. I have updated the code.
