無法登錄/ Facebook Unity SDK和Android

Question

Facebook Unity SDK：5.0.3測試版

當我嘗試登錄已安裝的Facebook應用程序時，它詢問我是否允許該應用程序訪問我的個人資料（然后我可以在我的個人資料應用程序頁面上的Facebook上看到確實具有訪問權限），但是此后沒有任何反應。 交互式控制台（Unity SDK附帶的示例）仍然沒有顯示我已被登錄的跡象。

這是當我按下登錄按鈕時在logcat中發生的事情：

D/FBUnitySDK(21729): KeyHash: BR6n1yxjFrxzrkkeDey3fzy7Mb0=
V/FBUnitySDK(21729): sending to Unity OnLoginComplete({"cancelled":true,"key_hash":"BR6n1yxjFrxzrkkeDey3fzy7Mb0=\n"})

如果我要刪除facebook應用程序，則會顯示一個小的webview，我應該在其中輸入我的憑據。 輸入后，它將只在兩個輸入字段都為空的情況下再次重新包裝，並且重新顯示沒有盡頭（除非我放棄並按Cancel / X）。

這是我嘗試登錄Webview時logcat中發生的情況：

在IOS上登錄可以正常工作，但是用Android怎么辦？

更新：在4.3.6 SDK版本上一切正常

Answer 1

您是否在沒有任何權限的情況下登錄？ 如果未指定權限，則存在一個已知的錯誤，其中FB.Login()不起作用。 試試FB.Login("basic_info", <your_callback>)

請參閱： Unity Beta SDK 5.0.3-在Android設備上登錄時出現問題

Answer 2

僅當我開始以縱向屏幕模式登錄時，登錄才有效。 如果我從橫向開始，它會強制變為縱向和縱向，但除此之外沒有任何反應。 測試了幾次，沒有重建-確認。 我相信這是一個錯誤。

Answer 3

SDK中存在嚴重問題。

該SDK使用幻像活動FBUnityLoginActivity ，該活動從onCreate（）調用FB.LoginUsingActivity（） ，但是該活動沒有android：configChanges屬性，並且由於從lansdcape切換為Portrait ，因此被Android重新啟動。 它導致對FB.LoginUsingActivity（）的第二次調用，這將取消先前的異步登錄。

解決方案是在所有活動上指定正確的android：configChanges和android：screenOrientation 。

我認為Facebook團隊應該使用runOnUiThread（）而不是幻像活動。
