I am working on an app that will need to connect to an external database and pull certain columns. I am looking for some help in opening a connection to the database. In another words, something like ODBC or JDBC in web development.

I've got a question about updating an app after release. If I have a database that contains 10 columns and I add a feature that requires an 11th column after the app has been released, where would I put the sql code to add the new column so that when they install the app it keeps their current data, but adds that 11th column? Is that even possible or would I need to create another table that references the first with a foreign key?

I create a set of RadioButtons in a RadioGroup on the fly (no XML), and would like to arrange them in either two columns or two rows - right now they are in a single column. I could of course create two sets of RadioButtons, and place each in a different RadioGroup view, but presumably then I would have to control the active state of each button by taking into account both views. Does anyone have an idea how to better do this?
