Re: [android-developers] Re: Refreshing ListView After Home Key is Pressed and Returning to App

If you're closing the SQLiteOpenHelper, it means you're closing the
database.

A closed database is just that, closed, and will need to be reopened -
e.g. in onRestart. You will also need to run a new query, to get a fresh
-- open -- cursor that you can work with.

A better way is to keep the database open at all times, and use a Java
singleton so that there is only one database object instance in the
entire application. This has been extensively discussed, search the list
archives.
