android - Xamarin android 应用抛出 ResourceNotFoundException

Question

从 1 周开始，我发现了 Xamarin 框架，我的工作是让 Android 应用程序正常运行。 iOS 应用程序之前已经启动。

我必须首先处理一些 NuGet 包依赖项，但现在我得到的唯一异常(exception)是:

这里看了很多帖子，好像是图标的问题，但是我检查了项目中的所有资源定义，资源名称，一切似乎都没有问题。

这个问题是否可能是由错误的引用(如 Xamarin Forms 或 Iconize)引起的？或者这可能只是因为缺少资源？

我已经清理了我的解决方案更新或降级了我的包，但没有任何效果..

我还必须说明我使用F#而不是C#来开发。我的 View 是用 XAML 制作的。

Answer 1

终于找到问题所在了

首先，我必须在 Build Action 字段中为我的所有资源文件设置“AndroidResource”(选择资源时在属性中查看)

其次，我不得使用 A 到 Z、0 到 9 和“_”等其他字符来命名我的资源。
