Google has also added tons more content to the indoor maps that are accessible from the app. Google said:

At the 2012 Consumer Electronic Show (CES) in Las Vegas, NV, attendees will now be able to use Google Maps on their Android devices to help them find their way in the sea of exhibitors and attractions throughout the Las Vegas Convention Center, select resorts and casinos along the Las Vegas strip, as well as the Las Vegas McCarran International Airport.

Starting today, we’re also releasing some of the first floor plans in Google Maps that were uploaded through the Google Maps Floor Plans tool. From malls to convention centers, museums and educational institutions from California to New York you will now be able to see these floor plans in Google Maps for Android.
