How to properly update a notification post api 11?

Question

• Before Notification.Builder came into existence the way to update a notification that was already in the notification tray was to call setLatestEventInfo()

Answer 1

The solution described here works well: Updating an ongoing notification quietly

The key is to use to reuse the builder and setOnlyAlertOnce(true):

if (firstTime) {
  mBuilder.setSmallIcon(R.drawable.icon)
  .setContentTitle("My Notification") 
  .setOnlyAlertOnce(true); 
  firstTime = false;
} 
mBuilder.setContentText(message)
.setProgress(100, progress, true);

mNotificationManager.notify(mNotificationId, mBuilder.build());
