Should the Notepadv3 tutorial close its database?

Androids Tutorial Notepad Notepadv3 opens its database, but never closes it explicitly. To make it correct, should Notepadv3 close its database, presumably with mDbHelper.close();and, if so, where should this line of code look?

Yes, you must close the adapter and cursors when you no longer need them (for example, when you finish your activity). This should be done according to the method onDestroy.
