使用一个活动登录Facebook，然后使用另一个活动注销它

Question

我正在使用Facebook登录应用程序。我成功从应用程序登录到Facebook，但注销不起作用。我正在使用facebook sdk 3.0，并在mainifest.xml中声明所有权限。这是注销按钮代码。

public void logoutFromFacebook() {
    mAsyncRunner.logout(this, new RequestListener() {
        @Override
        public void onComplete(String response, Object state) {
            Log.d("Logout from Facebook", response);
            if (Boolean.parseBoolean(response) == true) {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        btnFbLogin.setVisibility(View.VISIBLE);
                        finish();
                        btnFbGetProfile.setVisibility(View.INVISIBLE);
                    }
                });
            }
        }
        @Override
        public void onIOException(IOException e, Object state) {
        }
        @Override
        public void onFileNotFoundException(FileNotFoundException e,
                Object state) {
        }
        @Override
        public void onMalformedURLException(MalformedURLException e,
                Object state) {
        }
        @Override
        public void onFacebookError(FacebookError e, Object state) {
        }
    });
}

请帮忙，提前感谢。

此方法对我有用

public static void LogoutFB(Context context) {
    Session session = Session.getActiveSession();
    if (session != null) {
        if (!session.isClosed()) {
            session.closeAndClearTokenInformation();
            //clear your preferences if saved
        }
    } else {
        session = new Session(context);
        Session.setActiveSession(session);
        session.closeAndClearTokenInformation();
            //clear your preferences if saved
    }
}

我用了这个它的工作

// log out from facebook    
public static void callFacebookLogout(Context context) {
    Session session = Session.getActiveSession();
    if (session != null) {
        if (!session.isClosed()) {
            session.closeAndClearTokenInformation();
            // clear your preferences if saved
        }
    } else {
        session = new Session(context);
        Session.setActiveSession(session);
        session.closeAndClearTokenInformation();
        // clear your preferences if saved
    }
}
