I write the piece of code for checking if the device is oreo

    String NOTIFICATION_CHANNEL_ID = "my_channel_id_01";
    NotificationManager notificationManager1 = (NotificationManager) 
    getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "My Notifications", NotificationManager.IMPORTANCE_DEFAULT);

        // Configure the notification channel.
        notificationChannel.setDescription("Channel description");
        notificationChannel.enableLights(true);
        notificationChannel.setLightColor(Color.RED);
        notificationChannel.setVibrationPattern(new long[]{0, 1000, 500, 1000});
        notificationChannel.enableVibration(true);
        notificationManager1.createNotificationChannel(notificationChannel);
    }
     mNotification = builder
                .setLargeIcon(image)/*Notification icon image*/
                .setContentText(messageBody)
                .setSmallIcon(R.drawable.dhlone)
                .setContentTitle(title)
                .setStyle(new NotificationCompat.BigPictureStyle()
                .bigPicture(image).bigLargeIcon(image))/*Notification with Image*/
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent)
                .setBadgeIconType(R.drawable.dhlone)
                .setAutoCancel(true)
                .setSmallIcon(getNotificationIcon()) 
                .setLargeIcon(BitmapFactory.decodeResource(getApplicationContext()
                .getResources(),R.drawable.dhlone))
                .build();
                notificationManager1.notify(/*notification id*/0, mNotification);
