I want to add a SQLite tile provider to OSMDroid just like RMaps. I went through OSMDroid source code and its tile providers and I found that they are designed to get tiles from File, Archive file and internet.
I am using osmdroid-android 3.0.5.
I don't belive this is possible with the current Osmdroid library. If you want to do it you will have to create your own TileProvider to fit into the framework which should be possible.
I expect that using an archive file for the actual map tiles and a seperate database for your meta data is by far the simplest solution. Putting large amounts of data like the tiles into the database is not recomended.
