However, there's a nifty trick to make Hulu run on your Android 2.2 device; all you need to do is make Hulu think it's running on a desktop browser.
According to Absolutely Android, the procedure is as follows: Open the web browser on your Android device, type "about:debug" into the address bar and press Go. Go to settings, scroll to the bottom and select "UAString"; then change the setting to "Desktop," and enjoy Hulu on your Android device.
This trick has been tested on Google's Nexus One phone. Unfortunately, it comes with certain drawbacks; you get the desktop edition of Hulu instead of the version optimized for mobile devices; furthermore, it will likely get blocked by Hulu very soon.
