Android 应用从 google Play 商店下载后立即崩溃

Question

我创建了一个 Android 应用程序，当我在 Visual Studio 2019 年在我的 Android phone 上调试它时，它运行非常好。但是，当我将它发布到 Google 商店并下载它并运行在同一个 phone 上时，它立即崩溃。

堆栈跟踪是：

所以跟FreshTinyIoC有点关系。我只是不明白为什么当运行在我的 phone.

的调试模式下关闭 VS 2019 时这会起作用

如有任何想法，我们将不胜感激。

问题很简单，实际上您已经设置了链接到 SDK 和用户程序集，这意味着它正在链接所有内容，您的模型和其他所有内容 class，任何没有参考的内容都将被收集并删除为了更好地理解，您可以查看我的博客，其中有一整节介绍如何使用 Linking:

截至目前，我建议您暂时检查 Link SDK Assemblies，然后您可以 Link 所有内容，因为这需要一些时间
