Constructor Detail

ProviGenOpenHelper

public ProviGenOpenHelper(android.content.Context context,
                  String databaseName,
                  android.database.sqlite.SQLiteDatabase.CursorFactory factory,
                  int version,
                  Class[] contractClasses)

Create a helper object to create, open, and/or manage a database. This method always returns very quickly. The database is not actually created or opened until one of SQLiteOpenHelper.getWritableDatabase() or SQLiteOpenHelper.getReadableDatabase() is called.

Parameters:

context - the context to use to open or create the database.

databaseName - the name of the database file, or null for an in-memory database.

factory - the factory to use for creating cursor objects, or null for the default.

version - the version of the database. Each time the version is increased, missing columns will be added.
