I am finding alot of users for some reason are not upgrading my application when new versions come out. Is there a way for my application to query the Marketplace applicatio
The best would be to have a DB field with the current version on your server, and check the app version with the version mentioned in the back-end server every time the app loads.
But as CommonsWare mentioned, it might irritate some users.
Another possibility is to have an Check for Update button as I do inside the app itself.
Hope this helps....
