private 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) {
        CharSequence name = getString(R.string.channel_name);
        String description = getString(R.string.channel_description);
        int importance = NotificationManager.IMPORTANCE_DEFAULT;
        NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name,
       importance);
        channel.setDescription(description);
        // Register the channel with the system; you can't change the importance
        // or other notification behaviours after this
        NotificationManager notificationManager =
        getSystemService(NotificationManager.class);
        notificationManager.createNotificationChannel(channel);
