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()

I'm guessing (since I had the same trouble just now) that you are using a RemoteView in your notification. I managed to update the notification without it flashing like this:

RemoteViews views;
if( this.mNotification == null) {
    views = new RemoteViews(getPackageName(), R.layout.notification);
    this.mNotification = new Notification.Builder(this)
        .setContent(views)
        .setSmallIcon(R.drawable.status_icon)
        .setContentIntent(mNotificationAction)
        .setOngoing(true)
        .setOnlyAlertOnce(true)
        .getNotification();
} else {
    views = this.mNotification.contentView;
}
