偶尔 I/Choreographer(17165)：跳过 ## 帧黑屏锁定，Android Xamarin c#
Occasional I/Choreographer(17165): Skipped ## frames black screen lock up, Android Xamarin c#
偶尔，在导入照片或从 activity 返回应用程序（例如观看视频）时，我们的应用程序会锁定并出现黑屏，但某些功能仍会继续运行，例如 toasts。日志的结尾始终如一地说：
I/Choreographer(17165): Skipped ## frames! The application may be doing too much work on its main thread.
12-21 23:59:15.620 W/libEGL (17165): EGLNativeWindowType 0x77323f0010 disconnect failed
这是一个不一致的间歇性问题，因此很难确定。任何想法，将不胜感激。我假设一些线程问题锁定了 UI 线程，但因为它很少发生并且不容易重现，所以我真的不知道发生了什么。
编辑：只有当出于某些意图 activity 返回应用程序时才会发生这种情况，例如发送电子邮件、选择照片等。我已经设法通过一些适当放置的断点使其可重现。
这是我认为负责的 c# 代码。我添加了 REF(1) 2 和 3，以指示我的断点所在的位置。看起来 REF(2) 在冻结时永远不会到达，所以有时永远不会重新创建被破坏的表面，因此永远不会恢复渲染......我们正在使用可记录的表面视图，这是它的一个子类，请原谅我多长时间它是：

偶尔，在导入照片或从 activity 返回应用程序（例如观看视频）时，我们的应用程序会锁定并出现黑屏，但某些功能仍会继续运行，例如 toasts。日志的结尾始终如一地说：
I/Choreographer(17165): Skipped ## frames! The application may be doing too much work on its main thread.
12-21 23:59:15.620 W/libEGL (17165): EGLNativeWindowType 0x77323f0010 disconnect failed
这是一个不一致的间歇性问题，因此很难确定。任何想法，将不胜感激。我假设一些线程问题锁定了 UI 线程，但因为它很少发生并且不容易重现，所以我真的不知道发生了什么。
编辑：只有当出于某些意图 activity 返回应用程序时才会发生这种情况，例如发送电子邮件、选择照片等。我已经设法通过一些适当放置的断点使其可重现。
这是我认为负责的 c# 代码。我添加了 REF(1) 2 和 3，以指示我的断点所在的位置。看起来 REF(2) 在冻结时永远不会到达，所以有时永远不会重新创建被破坏的表面，因此永远不会恢复渲染......我们正在使用可记录的表面视图，这是它的一个子类，请原谅我多长时间它是：
