如何使用android sdk 3.0 beta获得Facebook附加权限？

Question

我正在使用官方的sdk beta 3.0为Android开发一个简单的Facebook应用程序.

我会为用户登录(user_likes,user_interests,friends_likes,等...),而不使用LoginButton获得额外的权限(如这里解释https://developers.facebook.com/docs/howtos/androidsdk/3.0/login-with -facebook /),事实上,我越来越有方法的其他权限

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        List<String> permission=new ArrayList<String>();
        permission.add("user_birthday");
        permission.add("user_likes");
        permission.add("user_questions");
        permission.add("user_interests");
        permission.add("user_relationships");
        permission.add("user_groups");
        permission.add("user_religion_politics");
        permission.add("friends_birthday");
        permission.add("friends_interests");
        permission.add("friends_likes");
        permission.add("friends_groups");
        permission.add("friends_questions");
        permission.add("friends_relationships");
       // this.openSession();
          this.openSessionForRead(app_id, permission);

    } 

实际上,它会打开登录视图,要求获得其他权限.

现在,我想知道如何获得更多的权限,因为,当我打电话user.get**()它不显示除了那些基础信息的其他方法.

谢谢!

我正在使用Null.pointer.exception

私有GraphObject mUser; ... //分配您从通话中获得的用户对象以获取用户的信息

String religion = mUser.getProperty("religion").toString();

这里我的logcat:

Answer 1

创建会话后,您可以获得其他权限.没有关闭会话

Session.NewPermissionsRequest newPermissionsRequest = new Session
                    .NewPermissionsRequest(this, Arrays.asList("user_groups"));

            session.requestNewReadPermissions(newPermissionsRequest);
