    super(context, DB_NAME, null, 1);
    

    in this statement last argument is database version.. set it to 2 for new updated APK. so existing user can have newly added table Or Column.

    on updated apk onUpgrade will call. and there you can copy database from asset. but than exisiting user will have loss of data.. so best option is to add table dynamically in database.
