Sorry. By "magic" I mean it has to be named CONTENT_URI and have the properties as listed. If you decided you didn't want to call it CONTENT_URI, it probably wouldn't work. > I thought onCreate() was a constructor, > i.e. whenever my app initialized and/or created an object, onCreate() > would be called. Java has its own constructors. onCreate() is a callback used by some Android classes. > It turns out the onCreate() is called if the datastore > doesn't exist. There are lots of onCreate() callbacks. I'm assuming you're referring to the SQLiteOpenHelper, whose onCreate() documentation says: "Called when the database is created for the first time." > I say that because I kept dropping my table in SQLite but the > ContentProvider.onCreate() was never called until I deleted the database > from the hard drive. Correct. The more conventional approach, on schema changes, is to increment the version number of the database (fourth parameter to SQLiteOpenHelper constructor), which will trigger an onUpgrade() call to your SQLiteOpenHelper object. > I assume all onCreates()s act similarly. For SQLiteOpenHelper implementations, yes. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 1.9 Available! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
