où est le problème? je deviens fou! Merci beaucoup!

Answer 1

Je pense que votre problème est que vous appelez explicitement surSessionStateChange dans votre méthode onResume, où le rappel l'aura appelée de toute façon (via onActivityResult, lorsque votre demande d'autorisation reviendra). Il en résulte 2 publient les demandes d'autorisation simultanément, ce qui est la raison pour laquelle vous voyez cette erreur. Essayez de supprimer la méthode onSessionStateChange dans votre onResume().
