Question

I have a ListActivity which lists a bunch of “things.” If you click on one of these “things,” you’re taken to another ListActivity which lists a bunch of “stuff” for that “thing.”

Say I want to give the user the ability to edit the name of some of the “stuff”; or even delete some of the “stuff.” At what point should I actually perform that action on my database?

Ex: If a row of “stuff” gets deleted, should the database be updated before I return my user to the list of “things?” Or should the user return to the list of “things” and then the database is updated? Or does it not matter?

Mind you the database updating will likely happen in a service (I’ll also be calling a web service to update the cloud).

Answer 1

I would do the database transaction after the user is finished messing with it, only because I would want to give them some way to undo an accidental deletion before committing it to the database.

Edit: See jball’s answer. He understood you better than I did.
