I haven’t tried this tutorial in particular, but I’ve played around with some of the Android Developer sample code and found it generally quite helpful.
Regarding your particular problem, there are a lot of little things which could be wrong, so it’s hard to work out the issue without seeing some code. Maybe you’re using the same drawable (@drawable/ic_tab_artists_grey) for both selected and un-selected state? What happens when you click on a tab?
As David said, it is very difficult to know the problem without seeing what in you various folders. I quickly tried the tutorial to see if there are any issues but all is fine. I run it with the same drawable images provided in the tutorial and the images are visible on both selected and unselected states. I have attached a zipped sample of the project if you need to counter check.

Hey, I downloaded your project and everything seems to be okay. So i really don’t understand your problem. Please specify your actual problem, steps you do so as to help reproduce the same scenario, what you expected and finally what you really get(in this case undesired results). This way it will be easier to assist you.
I don’t know why but when you build the app on android 4.0.3 the icons just don’t show up. Instead, I put build target android 3.2 and all worked just as you guys said.
I also didn’t know about this but when i checked around i realised you are not alone. One person asked the same question on stackoverflow but no one replied. http://stackoverflow.com/questions/8192708/images-used-for-tabs-not-visible-android-4-0. My guess would be that it is due to the fact that TabActivity is deprecated(i stand corrected), and it is advised to use fragments to to create tabbed interface and hence the way to go is to use Action bars. If you are really interested in this then you can find nice tutorials below on working with fragments.
