Going to throw a shameless plug... If you're looking to implement the action bar design pattern on all platforms in your app I have written a library which automatically abstracts and marshalls interactions to either the native ActionBar on 3.0+ or a custom third-party control on pre-3.0. You can find it at https://github.com/JakeWharton/ActionBarSherlock/.
If you only want the ActionBar on 3.0+, simple omit passing in a custom handler and your applications layout will be shown untouched on pre-3.0 devices. There are a few samples as well as a good bit of documentation. Let me know how you fare if you choose to use it. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
