Developers can now determine which devices a user has and customize their app or game experience accordingly, Facebook announced today in a blog post.
Using the Graph API, developers can retrieve a list of devices that a user has connected to Facebook.
Not only will developers be able to gain insights about their audience, but an app can use this information to tailor in-app content to users of different devices. For example, a canvas game looking to prompt users to download the mobile version can easily determine whether a user should be given an App Store link or a Google Play link.
Developers can also now restrict user-to-user requests based on device by using the “multi-friend selector.” For instance, an iPad app might want to present users with a list of only friends who also use Facebook for iPad.
