Question

我在Mac上卸载了Xamarin。然后重新安装它。 6.1.4（Build1）。现在我创建了一个新的解决方案选择了Portable Class Library。然后我编译。然后我安装在同一台机器上运行的模拟器上。但在发布会上，应用程序失败了。然后我检查了应用输出。以下是日志。我无法继续。请帮忙。我查了一下：“Xamarin.Android API-23支持”和“Mono运行时”都安装在模拟器android上。（卸载这些组件也没有解决）

提前致谢。

以下是日志：

遇到此问题时，通常的解决方案是将AndroidUseLatestPlatformSdk文件中的.csproj属性编辑为false给定项目，如下所示：

<AndroidUseLatestPlatformSdk>False</AndroidUseLatestPlatformSdk>

如果这不起作用，请尝试在Shared Runtime下的Project Properties中停用Android Options。

作为最后一个选项，您还可以尝试减少Target Framework下Project Properties下的General。

Xamarin Android应用程序刚刚启动后在Android上崩溃。缺少MonoRuntimeProvider
