How to convert arbitrary database to sqlite android by creating manager classes?

I know that the elegant way of handing a SQLite database in android is through creating manager classes that hold table constants and operations quote: http://ift.tt/1hyiL4m.

Does there exist a tool that will automatically generate these classes for an arbitrary, or at least some type of database D and once the android SQLite database E is generated, transfer the data from D to E.

Maybe a tool that at least uses the database schema, to generate the manager classes and I can program the part of transfering data for myself?

Thanks!
