The Great Gatsby, intruded and hungrily

Could you please tell me if "hungrily" in this extract from the chapter five of The Great Gatsby means "starving" or avidly" and if "intruding" means just "bust in" or "enter in such a way that we disturbed"?

We went upstairs, through period bedrooms swathed in rose and lavender silk and vivid with new flowers, through dressing-rooms and poolrooms, and bathrooms with sunken baths—intruding into one chamber where a dishevelled man in pajamas was doing liver exercises on the floor. It was Mr. Klipspringer, the “boarder.” I had seen him wandering hungrily about the beach that morning.

Thank you.
