Android: upgrading DB version and adding new table
...
Regarding #4: Wouldn't it be a better idea to use the oldVersion argument passed? If any upgrade statements are repeatable, you may end up repeating them on a mostly-up-to-date database. If one of the statements is to truncate a table, that would be very bad.

How do I check if a type is a subtype OR the type of an object?
...swer with the hope of someone sharing with me if and why it would be a bad idea. In my application, I have a property of Type that I want to check to be sure it is typeof(A) or typeof(B), where B is any class derived from A. So my code:
