Android Emulator: cette application ne fonctionnera pas sans les services Google Play

Depuis Android 4.2.2, il est possible d'exécuter les services Google sur l'émulateur Android. Je crée actuellement un Android application et fait un projet de test pour voir si je peux obtenir la connexion et la déconnexion de Google+ au travail.

J'ai suivi le tutoriel suivant: http://www.androidhive.info/2014/02/Android-login-with-google-plus-account-1/

Avec des informations supplémentaires utilisées à partir des tutoriels/sites suivants:

Les autres étapes que j'ai faites étaient:

À https://console.developers.google.com/project J'ai créé un projet avec:

API Google+ sur:

Google+ API on

Et un ID client créé avec le SHA1 correct et exactement le même espace de noms que le projet:

And a Client ID created with the correct SHA1

Chez Eclipse:

J'ai installé la bibliothèque google-play-services:

Google-play services installed

Et l'a ajouté au projet:

Google-play services library added (2)Google-play services library added (2)

J'ai également créé un émulateur avec la version 4.4.2:

I've also created an Emulator with version 4.4.2

Mais lorsque j'exécute l'application, j'obtiens l'erreur suivante, et cette erreur continue d'apparaître lorsque je clique sur le bouton:

Get Google Play services Error

Quelqu'un a une idée où ça va mal? Merci d'avance pour les réponses.

Ok, après avoir essayé certaines choses, il s'est avéré que j'avais une dernière option non correctement vérifiée, qui n'était mentionnée nulle part dans le (s) tutoriel (s) ..

Au lieu de Android 4.4.2 comme cible de construction de projet et cible d'émulateur, j'ai sélectionné les API Google 4.4.2. Maintenant, je ne reçois plus l'erreur des services Google Play.

Je reçois une NullPointerException, mais au moins je peux continuer ..;)

EDIT: correction de l'exception NullPointerException et modification du code dans mon message d'origine. Tout fonctionne comme il se doit maintenant et j'espère que ce message aide d'autres personnes ayant les mêmes (ou d'autres) erreurs à utiliser la connexion aux services google play à l'aide d'un émulateur Android Android.

Essayez d'utiliser le niveau 19 de l'API Google API comme cible d'émulateur au lieu du niveau 19 normal de l'API.
