        MyBusinessClass myBusinessClass = new MyBusinessClass();
        MyEntity myEntity = myBusinessClass.getMyEntity();
 
        DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
        Entity device = new Entity("gcmid","keyname");
        device.setProperty("account",user.getEmail());
        device.setProperty("device","idtelefonu1");

}

我读到有些人有这个问题,但没有写出如何解决它.我创建了新的debug.key并获得了新的sha1但不起作用.还试图用新包创建新的Android项目 – 没有用.
