Cette page présente une application exemple qui montre comment provisionner une application l'appareil et lui envoyer une commande de redémarrage. L'application utilise l'API Android Management bibliothèque cliente Java.
Avant de commencer
- Téléchargez la bibliothèque cliente Java de l'API Android Management. ajouter tous les fichiers JAR au chemin de classe.
- Créez ou sélectionnez un projet Google Cloud qui sera propriétaire du créée par une entreprise.
- Activer l'API Android Management dans le projet
- Créez ou sélectionnez un compte de service disposant du rôle de propriétaire ou d'éditeur sur la projet.
- Sélectionnez un compte Google pour vous inscrire à une nouvelle entreprise. Le compte ne peut pas être l'administrateur d'une entreprise préexistante.
- Définissez les constantes
PROJECT_IDetSERVICE_ACCOUNT_CREDENTIAL_FILEdans exemple de code. - Modifiez la constante
APP_PACKAGE_NAMEdans l'exemple de code pour installer l'application de votre choix.
