所以這裏是我堅持了一天以上的一天。 我正在嘗試執行新的Firebase規範到登錄用戶使用Facebook進入我的Android項目。新的Firebase版本 - Android - Facebook登錄無效
我真的很感謝任何能夠幫助我找出問題的人。
錯誤，我再次得到又一次
活動確實是在明顯的，我可以啓動它，但是當我點擊登錄按鈕，我得到以下錯誤（有什麼奇怪的是，它提到FacebookActivity而不是FacebookLoginActivity，這是我的活動）的名稱：

雙檢，在清單
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="@string/facebook_app_id" />
<activity
android:name=".activity.FacebookLoginActivity" />
