Question

我正在使用最新的Android SDK。对话框已打开，但输入凭据后对话框正在关闭，状态不会更改。

private StatusCallback statusCallback = new StatusCallback() {
    @Override
    public void call(Session session, SessionState state, Exception exception) {
        if (session.isOpened()) // call just one time and state is "opening"
            authWithToken("facebook", session.getAccessToken());
    }
};

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

    setContentView(new View(this));

    //setVisible(false);

    Settings.addLoggingBehavior(LoggingBehavior.CACHE);
    Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
    //Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_RAW_RESPONSES);
    //Settings.addLoggingBehavior(LoggingBehavior.REQUESTS);

    Session session = Session.getActiveSession();

    if (session == null) {
        session = new Session.Builder(this).build();
        Session.setActiveSession(session);
    }

    if (!session.isOpened()) {
        Session.OpenRequest openRequest = new Session.OpenRequest(this);
        openRequest.setPermissions(permissions);
        openRequest.setLoginBehavior(SessionLoginBehavior.SSO_WITH_FALLBACK);
        openRequest.setCallback(statusCallback);
        session.openForPublish(openRequest); //here dialog is opened, user is able to enter credentials 
    }

    if (session != null && session.isOpened()) {
        if (!hasEmailPermission()) {
            NewPermissionsRequest request = new NewPermissionsRequest(this, permissions);
            request.setCallback(statusCallback);
            request.setLoginBehavior(SessionLoginBehavior.SSO_WITH_FALLBACK);

            session.requestNewReadPermissions(request);
        }
    }

    if (session != null && session.isOpened())
        authWithToken("facebook", session.getAccessToken());
}

private boolean hasEmailPermission() {
    Session session = Session.getActiveSession();
    return session != null && session.getPermissions().containsAll(permissions);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    //never call this method 
    super.onActivityResult(requestCode, resultCode, data);

    Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}

我通过facebook oficial“入门”文档做了一切

Android Facebook SDK3.0, session state OPENING

不起作用，因为Facebook身份验证对话框从不调用onActivityResult（）

未安装Facebook应用程序。

更新

我检查了一下。 session.openForPublish(openRequest);关闭我的活动并打开Facebook Dialog。但为什么？

使用UiLifeCycleHelper类更改会话状态。

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash_screen);
        uiHelper = new UiLifecycleHelper(this, callback);
        uiHelper.onCreate(savedInstanceState);
}

Android facebook SDK身份验证不起作用
