通過Facebook登錄後無法通過Facebook登錄

Question

我正在嘗試使用Firebox實施2供應商（Facebook & Google）登錄活動。我測試過該系統，在以下情況下，退出由單一按鈕調用下面的定義signOut()方法來完成：

1. 登錄W/Facebook的，註銷，再次登錄W/Facebook的。
2. 通過Facebook登錄，註銷，使用Google登錄。
3. 登錄w/Google，註銷，再次登錄w/Google。
4. 登錄w/Google，註銷，再次登錄w/Facebook。

場景1-3是成功的，但是當我試圖與谷歌登錄，註銷，然後與Facebook登錄，我得到的OnCompleteListener在handleFacebookAccessToken方法onComplete方法ERROR_ACCOUNT_EXISTS_WITH_DIFFERENT_CREDENTIAL錯誤。奇怪的是，這隻發生在與Google簽約之後，我懷疑我沒有正確實施Google的註銷機制。

Answer 1

不完全回答你的問題，但你知道Firebase UI Auth？它的處理合並帳戶目前是我的應用程序，並且回購由Firebase和社區維護。

Answer 2

請檢查線程：https://groups.google.com/forum/#!searchin/firebase-talk/liu/firebase-talk/ms_NVQem_Cw/8g7BFk1IAAAJ它解釋了爲什麼發生這種情況。這是由於Google電子郵件被驗證的安全問題，而Facebook電子郵件則不是。
