【中文标题】偶尔的 I/Choreographer(17165):跳过 ## 帧黑屏锁定,Android Xamarin c#【英文标题】:Occasional I/Choreographer(17165): Skipped ## frames black screen lock up, Android Xamarin c# 【发布时间】:2020-04-30 12:29:20 【问题描述】:

有时在导入照片或从观看视频等活动返回应用程序时,我们的应用程序会锁定并出现黑屏,但某些功能仍会在下方继续运行,例如敬酒。日志的结尾一直说:

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

这是一个不一致且间歇性的问题,因此很难确定。任何想法,将不胜感激。我假设一些线程问题正在锁定 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:这只发生在从一些意图活动(例如发送电子邮件、挑选照片等)返回应用程序时。我已经设法通过一些放置良好的断点使其可重现。

这是我认为负责的 c# 代码。我添加了 REF(1) 2 和 3,以指示我的断点在哪里。似乎 REF(2) 冻结时永远不会到达,因此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,这是它的子类,请原谅我多久它是:

【问题讨论】:

当你阻塞主线程时会发生这种情况。如果您没有花一些时间缩小代码中的哪些部分阻止它,就很难为您提供帮助。 @Cheesebaron 感谢您的洞察力。我会尽量缩小范围。我能够辨别出它仅在从某些意图活动返回应用程序时发生。也许有没有被正确处理/捕获的异常? @rnisson,如果您发布一些代码并指出您遇到此问题的位置,这有助于我们分析您的问题。 @rnisson,我假设一些线程问题正在锁定 UI 线程,但我没有找到您的代码在哪里锁定了 UI 线程? @rnisson,很高兴听到您自己解决了您的问题,请给一个回复并将您的回复标记为答案,这对面临同样问题的其他社区成员很有帮助,谢谢。跨度> 【参考方案1】:

如果将来有人对此有任何问题,以前格式的销毁可记录表面代码会在返回时间歇性地运行。我把它移到了当应用程序表面被破坏并且它现在可以工作时暂停执行的代码。
