Android custom GPS map application

Question

I want to build an app that uses GPS data and a building map I provide to show the user where in the building on the map they are. This will be done in a specific building that i already know gets GPS and cell service.

At first I thought the easiest way to do this was to see if I could use Google maps to plot the users location and then just "overlay" my custom building map on top of the Google map so that I wouldnt have to deal with any of the gps information or the complexities of the mapping I would just have to scale my "overlay" to fit properly on top of the Google map so that the user was shown in the correct room in a building. I'm wondering if anyone can provide me any information on how to do this or if there is an easier way to accomplish my map. Any information at all is helpful!

Answer 1

You want... Google Map View

...and more specifically you will probably want to read the subsection appropriately titled: "Part 2: Adding Overlay Items"

EDIT: Whoops! Nevermind! I misread your question... that is only if you want to overlay an item on the map. Sorry...
