带 Prism 的 DryIoC 仅在 HUAWEI 上崩溃

Question

我的 Xamarin.Forms 应用程序出现以下错误。

Interpreter.TryInterpretAndUnwrapContainerException (DryIoc.IResolverContext r, FastExpressionCompiler.LightExpression.Expression expr, System.Boolean useFec, System.Object& result)
System.NullReferenceException: Object reference not set to an instance of an object

有趣的是，基于 AppCenter 崩溃，它只发生在装有 Android 9 或 10 的华为设备上。我想知道是否有人有任何线索/提示出了什么问题？

系统信息

• Xamarin.Forms 5.0.0.2125
• 棱镜 8.1.97
• 棱镜.DryIoc.Forms 8.1.97

Answer 1

NRE 没有提供很多信息：-( 此外，这个 Prism 版本使用旧的 DryIoc 版本，这使调查变得复杂。

从今天开始，原则上，您可以 fork Prism.DryIoc.Forms，将其更新到最新的 DryIoc v5.0.2（但使用 DryIoc 源包代替 DryIoc.dll 包）。 然后在您的项目中直接引用 Prism，并将断点放在TryInterpretAndUnwrapContainerException中。 检查此答案下的评论https://stackoverflow.com/a/72258242/2492669 。

我也有兴趣找出这个问题的真正原因。
