Question

我想在我的应用程序中从facebook获取电子邮件和用户名，所以我已经在我的片段中编写了必要的代码。单击“登录”按钮后，它将获取数据并要求获取从Facebook获取数据的权限。好之后它会抛出一个异常

  Error java.lang.UnsupportedOperationException: Session: an attempt was made to open a session that has a pending request.

我正在使用的代码是（我尝试过使用onActivityResult（））

 public class LoginFragment extends Fragment {


LoginButton loginWithFBButton;


 public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.activity_login, container, false);

    loginWithFBButton  = (LoginButton)v.findViewById(R.id.authButton);

    loginWithFBButton.setOnErrorListener(new OnErrorListener(){

            @Override
            public void onError(FacebookException error) {
                Log.i(TAG, "Error " + error.getMessage());
            }

          });

          // set permission list, Don't forget to add email
    loginWithFBButton.setReadPermissions(Arrays.asList("basic_info","email"));
          // session state call back event
    loginWithFBButton.setSessionStatusCallback(new Session.StatusCallback() {

        @Override
        public void call(Session session, SessionState state,
                Exception exception) {

            if (session.isOpened()) {
                      Log.i(TAG,"Access Token"+ session.getAccessToken());
                      Request.executeMeRequestAsync(session,
                              new Request.GraphUserCallback() {


                                @Override
                                public void onCompleted(GraphUser user,
                                        Response response) {
                                    // TODO Auto-generated method stub
                                     Log.i(TAG,"User ID "+ user.getId());
                                     Log.i(TAG,"Email "+ user.asMap().get("email"));
                                }
                              });


                  }
            else if (state.isClosed()) {

            }
        }
          });

        return v;
 }

    public void startActivityForResult(int requestCode, int resultCode, Intent data) {

        Session.getActiveSession().onActivityResult(getActivity(), requestCode, resultCode, data);
         super.onActivityResult(requestCode, resultCode, data);

    }

}

Answer 1

试试这个：

更改为：

    public void startActivityForResult(int requestCode, int resultCode, Intent data) {

    Session.getActiveSession().onActivityResult(getActivity(), requestCode, resultCode, data);
     super.onActivityResult(requestCode, resultCode, data);

}

到

    protected void onActivityResult(int requestCode, int resultCode, Intent data){

    Session.getActiveSession().onActivityResult(getActivity(), requestCode, resultCode, data);
     super.onActivityResult(requestCode, resultCode, data);

}

检索Facebook数据时出错
