Working with an SQLite database on Android can require some times more effort than what you should really give. For instance, if you ship a pre-configured and populated database with an application, you would need first to copy over the database to the specific database directory and then open it for reading and/or writing data to it. The SQLiteOpenHelper class provides a few methods that make life a bit easier but it does not provide a copy method for handling this issue. In addition to this, a check method would be required before copying the database and so on. Following on this, I implemented a SQLite adapter class to cover my needs as bellow:
– Copy database to the correct directory.
– Open and close the database.
– Execute raw SQL query.
– Execute SQL query for string, int, long, double.
– Drop table.
– Return count of a table.
– Download a db copy from Internet and replace local one.
