I have an Android app that uses the NotificationManager to inform the user of certain events. When I call .notify(), the icon I specify is shown in the status bar. It works fine on various Android 2.2 and 2.3 phones. But on a Galaxy Tab 10.1 running Android 3.1 the notification icon on the status bar is so dim it can barely be seen. I’ve seen one other app that has a similar problem, but all the other apps I’m using that do notifications look OK. I’ve followed the Guidelines at http://developer.android.com/guide/practices/ui_guidelines/icon_design_status_bar.html, including creating Android 2.3+ style icons and putting them in the drawable-hdpi-v9, drawable-mdpi-v9, etc. folders. The icons all look OK when I look at them on my development machine; they are the right colors and are not dim. What could I be doing wrong that is causing my notification icon to be shown so dim on the Honeycomb status bar?

As of today there is updated documentation available at the android developers web site:
