Database version code is independent of application version code. As for upgrading, you SqlOpenHelper.onUpgrade is passed both old (existing) and new (desired) version codes, so it knows just what columns to add.

Published without errors. Time 2) Application version code 2 and database version 2: some ALTER TABLE (added some columns). Published without errors, and application upgrades without errors. Time 3) very close to Time 2) Application version code 3 and database version 3: some other ALTER TABLE (added columns). If I publish version 3, what does it happen to a user that did not upgrade from version 1 to version 2? What happens to their database? In other words, is there a way the market has to keep track of the application versions and install the right version for the specific user? If not, how can I know if all my "version 1 users" had already upgraded to version 2?
