Android Oreo Does not Play Custom Sound for Notification

Finally I managed to find a solution on my own. Below is the code

NotificationManager mNotificationManager =                (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {            if(notificationSoundUri != null){                // Changing Default mode of notification                notificationCompatBuilder.setDefaults(Notification.DEFAULT_VIBRATE);                // Creating an Audio Attribute                AudioAttributes audioAttributes = new AudioAttributes.Builder()                        .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)                        .setUsage(AudioAttributes.USAGE_ALARM)                        .build();                // Creating Channel                NotificationChannel notificationChannel = new NotificationChannel(context.getString(R.string.channel_id_prayers),context.getString(R.string.channel_name_prayers),NotificationManager.IMPORTANCE_HIGH);                notificationChannel.setSound(notificationSoundUri,audioAttributes);                mNotificationManager.createNotificationChannel(notificationChannel);            }}mNotificationManager.notify(0, notificationCompatBuilder.build());
