Add extend access token feature

prabirshrestha commented 11 years ago

AppSecret should be ClientToken from https://developers.facebook.com/apps/{appid}/advanced?ref=nav and app type should be native/desktop

This method should be called every time the app starts/resumes.
User will have to add this code manually.
If no access token has been saved, should ignore extending access token.
also should make it easier for users to handle in case the ClientToken was reset. So they can show an error message that says to update the app.

FacebookSession.TryExtendAcessTokenAsync()?

@prabirshrestha Per this page https://developers.facebook.com/docs/facebook-login/access-tokens I don't believe it is possible to extend tokens without UI anymore unless the developer decides to include the AppSecret in the app (bad Idea). Is this feature request valid anymore?

This is currently not possible. Facebook in the iOS/Android SDK uses an internal API.

facebook-csharp-sdk / facebook-winclient-sdk
