Facebook Unity SDK：5.0.3 beta
当我尝试登录已安装Facebook应用程序时，它会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上的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）仍未显示我已记录的迹象。
以下是我按下登录按钮时在logcat中发生的情况：
D/FBUnitySDK(21729): KeyHash: BR6n1yxjFrxzrkkeDey3fzy7Mb0=
V/FBUnitySDK(21729): sending to Unity OnLoginComplete({"cancelled":true,"key_hash":"BR6n1yxjFrxzrkkeDey3fzy7Mb0=\n"})
如果我将删除Facebook应用程序，那么它会显示我的小webview，我应该输入我的凭据。输入之后，只需将两个输入字段都清空再次重新播放，再次出现就没有结束（除非我放弃并按下取消/ X）。
以下是我尝试登录webview时在logcat中发生的情况：

登录IOS工作得很好，但是我可以用android做错了什么？

上的一切正常答案 0 :(得分：1)
您是否在没有任何权限的情况下登录？如果未指定权限，则FB.Login()无效，这是一个已知错误。试试FB.Login("basic_info", <your_callback>)

答案 1 :(得分：1)
仅当我以纵向屏幕模式开始登录时，登录才有效。如果我在风景中开始它 - 它强有力地改变为肖像和背部，但除此之外没有任何事情发生。经过几次测试而没有重建 - 确认。我相信这是一个错误。
答案 2 :(得分：1)
SDK中存在严重问题。
SDK使用幻像活动 FBUnityLoginActivity ，它从 onCreate（）调用 FB.LoginUsingActivity（）但该活动没有 android：configChanges 属性，它由Android重新启动，因为它从lansdcape切换到肖像。它导致第二次调用 FB.LoginUsingActivity（），这将取消之前的异步登录。
解决方案是在所有活动中指定正确的 android：configChanges 和 android：screenOrientation 。
我认为Facebook团队应该使用 runOnUiThread（）而不是幻像活动。
