Google map API v2 custom overlay

Question

I am developing an android application for showing the floor map of a building inside google maps. I know there is Google floor plans, but it only available in selected countries. So I need to customize the google map. I am done a little by using the accepted answer in this link. But unfortunately I cant adjust the boundaries of the tiles here, thats not I needed. I only need to show the custom floor map only above the building i need to show, other area should be like the default Google maps. How can I achieve that?

Any help will be appreciated. Thanks in advance.

You could use GroundOverlays, which is a simple image which is shown above the map tiles as you define via geo bounds. See more here
