Notification vibrates on each progress update

Question

When on Android 8.0 (Oreo), every time there is an update to the progress of the notification, it vibrates. So the phone vibrates 100 times in the process. This only happens on Android 8.0 So i can assume I am having some improper use of their API. I am asking for help in stopping the vibration on each progress update of the notification. Here is my code:

Building Notification

mNotifyManager = (NotificationManager) mActivity.getSystemService(Context.NOTIFICATION_SERVICE); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) createChannel(mNotifyManager); mBuilder = new NotificationCompat.Builder(mActivity, "FileDownload")         .setSmallIcon(android.R.drawable.stat_sys_download)         .setColor(ContextCompat.getColor(mActivity, R.color.colorNotification))         .setContentTitle(mFile.getName())         .setContentText(mActivity.getResources().getString(R.string.app_name))         .setProgress(0, 0, true); mNotifyManager.notify(mFile.getId().hashCode(), mBuilder.build()); 

Create Channel method

  @TargetApi(26)   private void createChannel(NotificationManager notificationManager) {     String name = "FileDownload";     String description = "Notifications for download status";     int importance = NotificationManager.IMPORTANCE_MAX;      NotificationChannel mChannel = new NotificationChannel(name, name, importance);     mChannel.setDescription(description);     mChannel.enableLights(true);     mChannel.setLightColor(Color.BLUE);     notificationManager.createNotificationChannel(mChannel);   } 

onProgress

  @Override   public void onProgress(File file, double progress, long downloadedBytes, long totalBytes) {     mBuilder.setProgress(100, (int) (progress * 100), false);     mNotifyManager.notify(file.getId().hashCode(), mBuilder.build());   }

Using setOnlyAlertOnce(true) on your NotificationCompat.Builder when initially building the notification should do the trick.
