1. There may be a simpler solution in the future, but for now, the most straightforward way to determine whether a user has an app is to fetch the VIEWER object and determine whether it's non-null. If so, the user has your app installed. Otherwise, your app doesn't have access to the user's information and the object returned is null.
2. The developer guidelines do not allow direct links to install the current app because orkut provides this already. However, you are permitted to redirect the user to the install page IF they try to take a certain action that requires they have the app installed (e.g. posting a review, recording their high score, and so on). In this case, you can retrieve the current window location to get the gadget's ID and build the link manually: http://www.orkut.com/Main#AppInfo.aspx?appId=[gadget ID] I hope this helps. Let me know if you have any follow-ups. - Jason On Oct 10, 9:17 am, rd-london <[EMAIL PROTECTED]> wrote: > Hi, > > Got an OpenSocial application, wonder if someone can help. > > How can one easily test if a user has already installed the > application? > > Also - what's the best way to provide a link that the user can click > on to install the application if it isn't already installed - an add- > to-profile button/link in other words. > > Thanks for any help, > R --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Orkut Developer Forum" group.
