Indoor map for android with current location marker

Question

I am implementing an indoor positioning system and have reached the stage where I need to mark the location of a user in a building. I have the floor plan of the building but have no idea how to mark the users location on the floor plan or how to move the marker around. The map should stay static while the the marker indicating current position of the user should be able to move around on the map. Any pointers in the right direction are greatly appreciated.

Answer 1

You can use Google Indoor Maps as described in this tutorial. Or use custom map tiles as in that example of Alex Vasilkov.

Answer 2

if you know the layout of the routers, you can estimate where you are in the building based on signal strength... or just use google's api(Indoor Maps), which is discussed in: How to calculate distance from Wifi router using Signal Strength?
