Question

What is the best way to manage cached articles when it comes to
keeping the read state/unread state in sync? Is there a property
inside the article feed that will tell me the state of the item? I’m
trying to figure out how to keep the read state in sync, and if I need
to do a comparison of every cached article to the one on Google
Reader.

So far I’ve only been requesting unread items, so I exclude anything
that’s already been marked as read. However, I might have some cached
articles unread on the client that have been marked as read on Google
Reader. Those articles won’t be downloaded again, but I’d like to
perhaps do a check on launch of each unread article, to see if it
should still be displayed as unread.

Thanks for your time

There’s no reader API, so I believe you’re stuck with re-fetching the ‘unread items’ feed repeatedly, and removing any items that are no longer present in it. As far as seeing the status of items that are too old to be in the feed, I’m not sure if there’s a practical way to do that at all.

I’m not sure what you’re trying to accomplish, but bear in mind that, given the lack of an API, there’s no way for you to mark an item as read, either.
