Hi Kogan. You can store the items in the back-end and associate them with the user's ID. When a user tries to add an item, use a makeRequest call to send a signed HTTP request to your back-end with the item information. The ID of the user will be sent as a parameter with the signed request so you can properly associate the item with the user when you insert a new database record. Then, when the user removes an item, you can send another makeRequest to your back-end to delete the record.
In this way, your database will stay updated as your users interact with your app. Does this answer your question? - Jason On Oct 3, 2:15 pm, Kogan <[EMAIL PROTECTED]> wrote: > Hello Jason, > my use case is this - > > I want to save: > (*on my back end server, not using the persistence API or something > like that, that allows me a small memory space to use using Orkut > itself) > a list of lets say "items" for each user that has my application.
