启动android xamarin表单应用程序时出现异常

在VS 2017中，当我将构建配置从Debug更改为Release时，我在Xamarin中遇到了以下异常：

我相信你需要改变

StartService(new Intent(this, typeof(LocationService)));

到

有人建议我将Android项目属性中的链接选项从“Sdk和用户程序集”更改为“仅Sdk程序集”。这就解决了问题，我可以启动应用程序并将其部署到playstore。

这些可能是由于不正确的意图引发的，或者某个活动中的问题没有正确停止，我想我们可能需要查看一些代码来帮助您确定问题。您知道我应该在这里发布什么代码吗？应该是主窗口xaml、AndroidManifest还是其他什么？我认为“MainActivity”“OnCreate”方法是一个很好的起点。@Digitalsa1nt请查看编辑过的问题-我已附上MainActivity.cst感谢您的建议-不幸的是，它在版本配置中仍然显示相同的异常。

StartService(new Intent(this, typeof(LocationService)));

Intent serviceIntent = new Intent(this, typeof(LocationActivity));
context.StartActivity(serviceIntent);
