【问题描述】：

Facebook Unity SDK：5.0.3 测试版

当我尝试登录已安装 Facebook 应用程序时，它询问我是否允许此应用程序访问我的个人资料（然后我可以在我的个人资料应用程序页面中的 facebook 上看到确实提供了访问权限），但此后没有任何反应.交互式控制台（Unity SDK 附带的示例）仍然没有显示我已登录的迹象。

当我按下登录按钮时，logcat 中会发生以下情况：

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

如果我要删除 facebook 应用程序，它会向我显示小的 webview，我应该在其中输入我的凭据。输入后它会再次出现，两个输入字段都为空，并且这种重新出现没有尽头（除非我放弃并按取消/X）。

当我尝试登录 webview 时，logcat 中会发生以下情况：

在 ios 上登录可以正常工作，但我在 android 上可以做什么？

更新：在 4.3.6 SDK 版本上一切正常

【参考方案1】：

您是否在没有任何权限的情况下登录？有一个已知错误，如果未指定权限，FB.Login() 将不起作用。试试FB.Login("basic_info", <your_callback>)

见：Unity Beta SDK 5.0.3 - Problems logging in on Android device

【讨论】：

我正在使用指定的 basic_info 和电子邮件权限登录

【参考方案2】：

只有在我开始以纵向屏幕模式登录时才能登录。如果我以横向启动它 - 它会强制更改为纵向并返回，但除此之外什么也没有发生。在没有重建的情况下测试了几次 - 确认。我认为这是一个错误。

【讨论】：

感谢您的错误报告。我们正在调查。

与此同时，您可以自行修复：***.com/questions/21354281/…

【参考方案3】：

SDK 中存在严重问题。

SDK使用幻像活动FBUnityLoginActivity，它从onCreate()调用FB.LoginUsingActivity()，但是活动没有 android:configChanges 属性，并且它被 Android 重新启动，因为它从 lansdcape 切换到纵向。它会导致第二次调用 FB.LoginUsingActivity()，从而取消之前的异步登录。

解决方案是在所有活动上指定正确的 android:configChanges 和 android:screenOrientation。

我认为 Facebook 团队应该使用 runOnUiThread() 而不是幻像活动。
