Xamarin Android 启动时崩溃 "Got a SIGSEGV"

Question

我有一个 Xamarin Forms 应用程序，所以我打算发布我的应用程序，但我发现了一个错误，它只在旧的（2.3.7 和 4.0.4）xperia 设备或模拟器上出现，所以我的单击菜单中的应用程序图标后应用程序崩溃，这是我在输出中看到的内容：

虽然 Xamarin 支持 Android 的所有 API 级别，但 Xamarin.Forms 仅支持 API 级别 15+，您应该将 Minimum SDK 设置为 15。这是我们的文档:

http://developer.xamarin.com/guides/cross-platform/xamarin-forms/introduction-to-xamarin-forms/#Requirements

这意味着 Xamarin.Forms 支持所有 Android 设备中的 94%：https://developer.android.com/about/dashboards/index.html?utm_source=suzunone
