Hi, Android Google Maps Version 2 has support to draw map tiles from alternate sources. You just need to provide your floor map as a pyramid of map tiles, typically 256x256 pixels. The map tiles then are accessed (from your cloud server) based on lat, lon & zoom level. You can position that map view based on the user's location. See https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/model/TileOverlay etc and search in stackoverflow for additional help eg http://stackoverflow.com/questions/13695393/open-street-maps-with-android-google-maps-api-v2
I won't discuss how you can get directions indoors particularly if that involves changing floor levels. But you can draw lines, polygons etc with Android Google Maps Version 2 as well. For vision impaired I'd also suggest providing Text to Speed audio directions.
