Android 上的 Xamarin 有随机 System.ArgumentException。它是完全随机的——它可以随时随地在任何平台上发生。我们在 5.1、5.0、4.4.4 上注册了它。

它没有足够的堆栈跟踪,它没有抛出的地方,我无法用任何东西捕捉到它。我认为它可能与 async void 有某种关系,我们在项目中使用 MVVMCross 并且有许多 async void Initasync void DoMvxCommand 方法.但它们都包含在 try-catch block 中。

我非常需要有关如何修复或至少找到崩溃原因的任何建议。这是最新的崩溃日志

最佳答案

Android 抛出 NullRefenceException 时我遇到了非常相似的问题它看起来是随机的(这实际上是因为事情是异步/并发运行的)并且它们永远不会在正确的位置中断并且 StackTrace 完全没有值(value)。查看线程和解决方案 here .

无论如何,让我弄清楚问题的解决方案的两个部分是:

  1. 打开 Visual Studio 中的设置以中断/引发特定异常。为此,请前往 this post .该帖子描述了转到 Visual Studio -> 调试 -> 异常...(或 Ctrl + Alt + E )

然后,要查找该异常,请展开“公共(public)语言运行时异常”->“系统”-> 然后选中“System.ArgumentException”旁边的“抛出”框。现在,它有望在异常实际发生的那条线上中断。此外,一旦问题得到解决,您肯定会希望将其关闭,这样您就不会开始遇到您并不真正需要处理的异常。

  1. 覆盖 Android 的异常处理程序事件,称为 UnhandledExceptionRaiser ,然后在事件中设置断点,以帮助您在应用程序崩溃之前捕获其中的一些异常。 Activity 信息可在 this post 中找到(我最后只是将该事件放入 MainActivity.cs 中。

这是我的异常事件代码:

AndroidEnvironment.UnhandledExceptionRaiser += (sender, args) => {
args.Handled = false;
};

我只是在 args.Handled 上设置了一个断点并查看详细信息,但您也可以打印出异常或其他内容。

  1. 最后,我自己发现但听其他人提到的另一件事是,您通常可以通过深入了解异常详细信息并找到 captured_traces 来找到更有用的异常源信息。 .

要找到它,您需要不断扩展异常实例的 base属性,在异常详细信息窗口中,直到您进入 System.Exception .然后执行以下步骤(尽管有时您必须在执行以下步骤之前进入内部异常):

System.Exception -> Non-public members -> captured_traces -> 那么你通常需要 [0]但有时还有其他人需要查看 -> Non-public members -> frames -> 现在你通常要么想要 [0]或者你想要列表中的最后一个 -> Non-public members -> 最后您将能够在 fileName 中看到该文件属性和“lineNumber”属性中的行号(想象一下)。

现在我确定有一种奇特的方法可以通过反射或其他方式提取此信息,而无需深入了解异常细节。如果有人知道怎么做,我很想听听!
