What is the best way to work with the sqlite database in android?
The sqlite database file (copy it for the first time into the application environment)
OR
Creating the tables in code (in database helper’s onCreate())
My database has 6 tables and it is empty for the first time. I ask this because I want to update my database in the future and would want to know the best approach for this.
Thank you!
You should create (in code) it the first time it is used. Android offers the SQLiteOpenHelper class that should be used for it. SQLiteOpenHelper defines the following methods:
onCreate(SQLiteDatabase db): invoked when the database is created, this is where you can create tables and columns to them, create views or triggers.onUpgrade(SQLiteDatabse db, int oldVersion, int newVersion): Invoked if the used database is older than the current version. Handle here the upgrade stuff (data migration, table creation/deletion)See here for a good tutorial: http://www.codeproject.com/KB/android/AndroidSQLite.aspx
