登录后，我可以，我可以做FB查询。几分钟（扮演游戏）的Facebook请求后失败的异常：

After login I can I can make FB queries. After few minutes (played game) Facebook requests fail exception:

java.lang.IllegalStateException: Cannot execute task: the task is already running

当我把它称为失败

        Request.executeMeRequestAsync(Session.getActiveSession(),
                new Request.GraphUserCallback() {...

        Request.executeGraphPathRequestAsync(Session.getActiveSession(),
                "me/apprequests", new Request.Callback() {...

        Request request = new Request(session, "me/apprequests", null,
                    null, new Request.Callback() { .... } );
        RequestAsyncTask status = request.executeAsync();

同样的呼叫将被立即登录后，他们的工作叫。 我有一个测试应用程序，它的工作原理。但在登陆后几分钟后真正的应用程序这是行不通的。

Same calls are called immediately after login and they work. I have a test app where it works. But in real app after few minutes after login it does not work.
