I did not see a Facebook opengraph tutorial under the Java Api so I was not sure if the feature was supported. If it does not, will this feature be added soon?

Yes, you can use facebook open graph with the native java sdk. There is a `myClient.User().loginFacebookBlocking(...)` you can use to login, and you can use the standard variations of `appdata.saveBlocking(...)` as opposed to `appdata.save(...)`of the Android library.
The only thing to take care of is retrieving a facebook token, as I don't think facebook has a native SDK. You can take a look here: https://developers.facebook.com/docs/sdks/ and they provide a Spring plugin, or you can consume their REST endpoints directly.
