L'utilisation de YouTube Données de l'Api Android

Suis en train d'utiliser YouTube Api de Données dans mon application android. Quand j'essaie de le lancer comme un projet en java, il fonctionne très bien sans aucune erreur. Mais quand j'essaie de faire la même chose dans mon application android , l'application de la force se ferme. Voici le résultat de logcat et mon code.
