android - Facebook API 2.1 - About Invite Friends And App-scoped User IDs -


  Facebook will start to issue app-scod user id, when people first enter your app instance Will, 0 of v2 API With an app-scod id, the id for the same user will be different between the app   

Send a request when inviting a friend: {to [0] = 10202585439492947 , Request = 345936808908087}, I can get the ID of the recipient: 10202585439492947, this is the recipient's app-scottch user ID?

Will the user's app-scod user ID always be the same? If the user takes away my app, then after several days, log in to my app again, will the app-scope user ID be the same as before?

Me Rewarded From and Recipient , but if the app-scoped user ID has been changed between the sender then Send invitations and recipients logs to the app, so I can invite that new user.

I have responded to another thread:

This is an App Scod ID, and this should be the same, even if the user authorizes and authorizes their app. It will always be the same in an app, but it will be different in the second app if you want to match the ID between different applications, then you can use the Business Mapping API:

BTW, you can Only the sender is allowed to reward if the receipt has accepted the invitation, and nothing else. View Forum Policy: 4.5 & gt; Click the small question mark icon.

However, if you are using "Invitable_friends" carefully, you do not get App Scod Id, but "Invitation token":

Edit: Scope ID can change If the user authorizes the app and authorizes it again after a long time, but you have to delete its data for privacy reasons anyway.
