Android Cant从Facebook SDK 4获取所有用户信息

Question

我正试图从Facebook SDK获取所有信息。实际上这段代码正在运行，但我遇到了问题。此代码无法从所有Facebook帐户获取所有信息。当我从我的帐户登录时，它正确地获取了我的所有信息，但是从其他2个不同的帐户中它没有全部并且返回null。他们在他们的个人资料中有电子邮件或城市信息，甚至他们给予权限我的代码不接受这些信息。

protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_login);
       user = PrefUtils.getCurrentUser(LoginActivity.this);


        btnLogout = (TextView) findViewById(R.id.btnLogout);
        btnLogout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                PrefUtils.clearCurrentUser(LoginActivity.this);

                LoginManager.getInstance().logOut();


                Intent i = new Intent(LoginActivity.this, LoginActivity.class);
                startActivity(i);
                finish();
            }
        });
    }

    @Override
    protected void onResume() {
        super.onResume();


        callbackManager = CallbackManager.Factory.create();


        loginButton = (LoginButton) findViewById(R.id.login_button);
        profileImage = (ImageView) findViewById(R.id.profileImage);
        loginButton.setReadPermissions("public_profile", "email", "user_friends", "user_birthday", "user_location");

        btnLogin = (TextView) findViewById(R.id.btnLogin);
        btnLogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                progressDialog = new ProgressDialog(LoginActivity.this);
                progressDialog.setMessage("Loading...");
                progressDialog.show();

                loginButton.performClick();
                loginButton.setPressed(true);
                loginButton.invalidate();
                loginButton.registerCallback(callbackManager, mCallBack);
                loginButton.setPressed(false);
                loginButton.invalidate();

            }
        });
    }
