My device has the Facebook application and if the user has already identified himself through Facebook app, I would like that it won't be done through my app a second time (only rights demand). I searched on the web without success and the examples with Facebook SDK always ask an idendification.
I know that is possible under iOs. Is it under Android ? And if yes, how can I manage that ?
Thanks.
(Thanks ZouZou to have translate)
My bad, this question is outdated.
Indeed, in the version 3 of the facebook SDK it's efficiently manage.
Just follow scrupulously the "How to" : https://developers.facebook.com/docs/getting-started/facebook-sdk-for-android/3.0/
Have fun.
