Update External SQLite Database

I have an App shipped with an external SQLite database on Play Store. The app works fine but when i did update (change database content) of the App on Google Play, the database still reflects the old one. Please how can I make the App to access the latest database.

Below is my DatabaseOpenHelper code.

public class DatabaseOpenHelper extends SQLiteAssetHelper {
private static final String DATABASE_NAME = "mydb.db";
private static  int DATABASE_VERSION = 1;


public DatabaseOpenHelper(Context context) {
    super(context, DATABASE_NAME, null, DATABASE_VERSION);
}

}

Someone suggest I should change the DATABASE_VERSION to something but the App crashes when I did so.
