Solution:

On Android 8.0 (Oreo) you must have something called as a NotificationChannel So try the below implementation:

Step1: Create Notification Channel

private void createNotificationChannel() {

    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);
        NotificationManager notificationManager = getSystemService(NotificationManager.class);
        notificationManager.createNotificationChannel(channel);
    }
}

Finally: Then your Notification:

 NotificationCompat.Builder mBuilder =   new NotificationCompat.Builder(activity)
                .setSmallIcon(R.drawable.ic_launcher_background) // notification icon
                .setContentTitle("Notification!") // title for notification
                .setContentText("Hello word") // message for notification
                .setAutoCancel(true); // clear notification after click
Intent intent = new Intent(activity, RecorderActivity.class);
PendingIntent pi = PendingIntent.getActivity(activity,0,intent, PendingIntent.FLAG_UPDATE_CURRENT);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mBuilder.setContentIntent(pi);
notificationManager.notify(1, mBuilder.build());

Try this, Hope it helps.
