Je suis coincé dans une boucle ici.Firebase/Facebook - Comment se déconnecter/se déconnecter?
Les utilisateurs peuvent se connecter avec leur compte FB. L'application crée un utilisateur Firebase avec les mêmes informations. Avec l'activité lanceur (LoginActivity), s'il détecte qu'un utilisateur est déjà connecté, il le redirige vers son fragment de profil.
- Cependant, sur le fragment de profil, je clique sur le bouton de déconnexion et redirige vers la page de connexion. C'est là que le cycle commence. À partir des extraits de code et du document officiel Firebase, j'utilise .unauth() ;. Cependant, mon logcat montre toujours que l'utilisateur est connecté. J'ai également essayé d'utiliser la méthode Facebook SDK de LoginManager, mais cela n'a pas fonctionné non plus.
