Write Java code to "put more information in the DB but without erasing parameters set by the user". For example, if you are using SQLiteOpenHelper, increment the version number of your schema. That will cause onUpgrade() to be called in your SQLiteOpenHelper subclass the first time your app is run after the upgrade. There, you can execute whatever code you want to adjust the schema and/or data in the database. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android Training in London: http://bit.ly/smand1 and http://bit.ly/smand2 -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
