我能夠連接到我的應用程序在Android上的Facebook，並看到我的名字，姓氏等字段。然後我在我的電腦上登錄Facebook.com，並從允許的應用程序中刪除我的應用程序，然後重新啓用（FOR TESTING）。Android Facebook錯誤驗證訪問令牌
後來，當我跑我的申請，我得到以下錯誤的logcat：
FacebookError: Error validating access token: Session does not match current stored session.
這可能是因爲用戶自會話創建或Facebook已經改變了會議的時間更改密碼安全原因。
我嘗試了一切，搜索論壇 - 但沒有運氣。
