Android：Sqlite数据库升级openOrCreateDatabase

Question

Have used openOrCreateDatabase to create a SQLiteDatabase associated with my application package. Wat does setVersion api do? Now my DB is getting upgraded on newer version of my app.Is there any upgrade callback? OR we need to use SQLiteOpenHelper to get upgrade callback?

Answer 1

openOrCreateDatabase() just opens the database file, creating a new one if one doesn't already exist.

There's no versioning involved, and no schema creation / upgrade callbacks. SQLiteOpenHelper is an easy way to provide such functionality.

To learn how SQLiteOpenHelper does the versioning and invokes callbacks, see the source .
