从Visual Studio构建[ProjectName].Android Xamarin.Forms应用程序时，模拟器卡在手机启动屏幕上。

Question

我正试图从Visual Studio的模拟器上构建和测试我的Xamarin.Forms Android应用程序，但模拟器却卡在了屏幕上。

屏幕上出现了下面的信息，点击后，屏幕上出现了下面的信息。等一下，它又开始显示 电话开始了

下面提到的是构建输出。

更新

我从设备管理器中单独启动模拟器并构建Android解决方案后，发现了下图中给出的信息。

而这是显示的输出。

2>Starting deployment to pixel_2_pie_9_0_api_28 ...
2>Starting emulator pixel_2_pie_9_0_api_28 ...

但是在点击部署错误弹出窗口中的 "是 "或 "否 "后，输出窗口中仍然没有错误。

Answer 1

回答我自己的问题。

首先是HAXM的问题，它没有安装。

然后关于部署错误，在我的情况下，模拟器的名称从Android设备管理器的默认名称被更改。所以我把它改回了默认名称，也就是在添加新设备时给出的名称（例如Nexus 5X）。

这对我来说是可行的，但却花了很长时间来构建和部署!
