https://developers.facebook.com/docs/howtos/androidsdk/3.0/login-with-facebook/の指示に従いました。「ログイン」ボタンに触れると、セッション状態は常にOPENINGです。ユーザーのウォールにストーリーを投稿しようとすると、次のエラーが表示されます

「セッション: 保留中の要求があるセッションに対して新しいアクセス許可を要求しようとしました。」

これが私のコードです：

public class MainFragment extends Fragment {
    private static final String TAG = "MainFragment";
    private UiLifecycleHelper uiHelper;

    private Session.StatusCallback callback = new Session.StatusCallback() {
        @Override
        public void call(Session session, SessionState state,
                Exception exception) {
            onSessionStateChange(session, state, exception);
        }
    };

    private void onSessionStateChange(Session session, SessionState state,
            Exception exception) {
        if (state.isOpened()) {
            Log.d(TAG, "Logged in...");
        } else if (state.isClosed()) {
            Log.d(TAG, "Logged out...");
        } else {
            Log.d(TAG, "Unknown state: " + state);
        }
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        uiHelper = new UiLifecycleHelper(getActivity(), callback);
        uiHelper.onCreate(savedInstanceState);
    }

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

        // For scenarios where the main activity is launched and user
        // session is not null, the session state change notification
        // may not be triggered. Trigger it if it's open/closed.
        Session session = Session.getActiveSession();
        if (session != null && (session.isOpened() || session.isClosed())) {
            onSessionStateChange(session, session.getState(), null);
        }

        uiHelper.onResume();
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        uiHelper.onActivityResult(requestCode, resultCode, data);
    }

    @Override

        uiHelper.onPause();
    }

        uiHelper.onSaveInstanceState(outState);

            Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.facebook_login, container, false);
        LoginButton authButton = (LoginButton) view
                .findViewById(R.id.authButton);
        authButton.setFragment(this);

        return view;
    }

    private boolean isSubsetOf(Collection<String> subset,

    }

    private static final List<String> PERMISSIONS = Arrays
            .asList("publish_actions");
    private static final String PENDING_PUBLISH_KEY = "pendingPublishReauthorization";
    private boolean pendingPublishReauthorization = false;

    public void publishStory() {
        Session session = Session.getActiveSession();

        if (session != null) {

            // Check for publish permissions
            List<String> permissions = session.getPermissions();
            if (!isSubsetOf(PERMISSIONS, permissions)) {
                pendingPublishReauthorization = true;
                Session.NewPermissionsRequest newPermissionsRequest = new Session.NewPermissionsRequest(
                        this, PERMISSIONS);
                session.requestNewPublishPermissions(newPermissionsRequest);
                return;
            }

            Bundle postParams = new Bundle();
            postParams.putString("name", "Facebook SDK for Android");
            postParams.putString("caption",
                    "Build great social apps and get more installs.");
            postParams
                    .putString(
                            "description",
                            "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
            postParams.putString("link",
                    "https://developers.facebook.com/android");
            postParams
                    .putString("picture",
                            "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");

            Request.Callback callback = new Request.Callback() {
                public void onCompleted(Response response) {
                    JSONObject graphResponse = response.getGraphObject()
                            .getInnerJSONObject();
                    String postId = null;
                    try {
                        postId = graphResponse.getString("id");
                    } catch (JSONException e) {
                        Log.i(TAG, "JSON error " + e.getMessage());
                    }
                    FacebookRequestError error = response.getError();
                    if (error != null) {
                        Toast.makeText(getActivity().getApplicationContext(),
                                error.getErrorMessage(), Toast.LENGTH_SHORT)
                                .show();
                    } else {
                        Toast.makeText(getActivity().getApplicationContext(),
                                postId, Toast.LENGTH_LONG).show();
                    }
                }
            };

            Request request = new Request(session, "me/feed", postParams,
                    HttpMethod.POST, callback);

            RequestAsyncTask task = new RequestAsyncTask(request);
            task.execute();
        }

    }
}

どうしたの？

編集：「ログイン」ボタンのテキストは変更されないことにも言及したいと思います。認証中にエラーは発生しませんが、読んだ限りでは「ログアウト」に変わるはずです。

最後に、これは私にとってはうまくいきます。キーポイントは追加することでした

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    uiHelper.onActivityResult(requestCode, resultCode, data);
}

と

        loginBtn.setFragment(this);
    loginBtn.setUserInfoChangedCallback(new LoginButton.UserInfoChangedCallback() {
        @Override
        public void onUserInfoFetched(GraphUser user) {
            graphUser = user;
        }
    });

フラグメント内のコード:

private GraphUser graphUser;
private UiLifecycleHelper uiHelper;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    uiHelper = new UiLifecycleHelper(getActivity(), callback);
    uiHelper.onCreate(savedInstanceState);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return inflater.inflate(R.layout.test_frame, container, false);
}

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    view.findViewById(R.id.getMeBtn).setOnClickListener(this);

    LoginButton loginBtn = (LoginButton) view.findViewById(R.id.loginBtn);
    loginBtn.setFragment(this);
    loginBtn.setUserInfoChangedCallback(new LoginButton.UserInfoChangedCallback() {
        @Override
        public void onUserInfoFetched(GraphUser user) {
            graphUser = user;
        }
    });
}

@Override
public void onResume() {
    super.onResume();
    uiHelper.onResume();

    updateUI();
}

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    uiHelper.onSaveInstanceState(outState);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    uiHelper.onActivityResult(requestCode, resultCode, data);
}

@Override
public void onPause() {
    super.onPause();
    uiHelper.onPause();
}

@Override
public void onDestroy() {
    super.onDestroy();
    uiHelper.onDestroy();
}

private Session.StatusCallback callback = new Session.StatusCallback() {
    @Override
    public void call(Session session, SessionState state, Exception exception) {
        onSessionStateChange(session, state, exception);
    }
};

private void onSessionStateChange(Session session, SessionState state, Exception exception) {
    updateUI();
}

private void updateUI() {
    if (graphUser != null) {
        Log.d("TEST", graphUser.getFirstName());
    }
}

@Override
public void onClick(View view) {
    Session session = Session.getActiveSession();
    Log.d("TEST", "session.getState() = " + session.getState());

    if (session.getState().isOpened()) {
        Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {

            @Override
            public void onCompleted(GraphUser user, Response response) {
                if (user != null) {
                    updateUI();
                }
            }
        });
    }
}

onActivityResultフラグメントではなく、アクティビティに実装する必要があります。私のために働いた。

これが発生する可能性があるさらに別の理由 (私の場合) は、バグのgetChildFragmentManager()ために onActivityResult がネストされた Fragments に渡されない場合です。 これ(ホスティング Fragment が受け取った onActivityResult をすべての子に渡す) が、私を助けてくれました。
