Is it necessary to extends SQLiteOpenHelper.I just want to copy the database(read only) from aseets folder.
It is not necessary to extends SQLiteOpenHelper,To create and upgrade a database in your Android application you usually subclass “SQLiteOpenHelper”. In this class you need to override the methods onCreate() to create the database and onUpgrade() to upgrade the database in case of changes in the database schema. Both methods receive an “SQLiteDatabase” object.
SQLiteOpenHelper provides the methods getReadableDatabase() and getWriteableDatabase() to get access to an “SQLiteDatabase” object which allows database access either in read or write mode.
For the primary key of the database you should always use the identifier “_id” as some of Android functions rely on this standard.
