The problem was i am using Android O and it requires more information. Here is the successful code for android O.

    mNotifyManager = (NotificationManager) mActivity.getSystemService(Context.NOTIFICATION_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) createChannel(mNotifyManager);
    mBuilder = new NotificationCompat.Builder(mActivity, "YOUR_TEXT_HERE").setSmallIcon(android.R.drawable.stat_sys_download).setColor
            (ContextCompat.getColor(mActivity, R.color.colorNotification)).setContentTitle(YOUR_TITLE_HERE).setContentText(YOUR_DESCRIPTION_HERE);
    mNotifyManager.notify(mFile.getId().hashCode(), mBuilder.build());

@TargetApi(26)
private void createChannel(NotificationManager notificationManager) {
    String name = "FileDownload";
    String description = "Notifications for download status";
    int importance = NotificationManager.IMPORTANCE_DEFAULT;

    NotificationChannel mChannel = new NotificationChannel(name, name, importance);
    mChannel.setDescription(description);
    mChannel.enableLights(true);
    mChannel.setLightColor(Color.BLUE);
    notificationManager.createNotificationChannel(mChannel);
}
