Found this in the HULU support forums.
Thanks for posting. There was a error that mistakenly put the Hulu Plus app in the store for the Galaxy Nexus. Hulu Plus is currently not supported or certified on this device, so while it may have worked for you, the app wasn't tested or debugged, so the ultimate user experience could've been very poor. We are working hard to roll Hulu Plus out across Android devices, including the Galaxy Nexus, but we do not have a timeline to announce at this time. We sincerely apologize for any confusion or inconvenience this may have caused. Any questions, just let me know.
