由於以前使用facebook的片段登錄和現在的需求變化很好，所以現在facebook登錄活動，所以我們有正常的android按鈕，並點擊登錄對話框將出現用於用戶交互的用戶名和密碼，以及當登錄成功時請求用executeme獲取用戶詳細信息。每個代碼都完成，但是當點擊按鈕對話框時不會出現，但onsession狀態將日誌顯示爲輸出爲facebook sdk 3.0登錄android活動類
第一顯示打開 比顯示登錄失敗關閉
所有的步驟都需要登錄facebook在facebook上提到應用程序開發站點執行，所有需要的類和元數據信息也在andriod清單文件中給出。
這裏的活性類進行登錄

Log.e（ 「SessionState的」， 「」 +狀態）;這裏顯示LOGIN FAILED CLOSED。
