Most of you Android junkies out there have probably been using Google Maps on your phone since day one. A big reason Android is such a powerful platform, Google Maps offers GPS enabled Maps, location-based search, and even turn-by-turn navigation. With version 6.0 being recently released, Google brings something new to the table with maps of indoor spaces.
To use the new features, simply zoom in to the point where you're given the ability to view the interior map. If you don't have any supported buildings close by, you could try out the functionality by searching for Chicago's O'hare Airport . Google even provides the ability to switch floors based on your current GPS location or manually using the controls on the right-hand side.
