我在 Visual Studio 中从 Android 设备管理器启动 Android 模拟器 Nexus 5 时遇到问题，我尝试启用 Hyper-V、AEHD 和 HAXM，但没有成功。由于某种原因，我在“adb devices”中看不到模拟器，而且当我启动它时，我无法从 Android 设备管理器中停止它。
我尝试按照 Microsoft 进行故障排除，但没有帮助，我无法通过 CMD“emulator -avd avd_name [ {-option [value]} … ]”启动模拟器，我也尝试重新安装 SDK，但没有成功帮助。当我开始使用该模拟器进行调试时，它刚刚开始部署并出现进度条，但它冻结在那里，我等了 1 小时但什么也没发生。你知道我应该如何解决这个问题吗？

我在该路径上找不到vendor.img.qcow2
我找到了一种通过右键单击 .Droid 项目文件来启动模拟器的方法，在“属性”部分，我看到“使用设置为 Anroid 8.1 (Oreo) 的 Android 版本进行编译”，并且我为 Nexus 5 手机下载了基于 x86 架构的模拟器，但我仍然有在模拟器上显示任何内容的问题，我只是有空白屏幕。我还获得了该模拟器的vendor.img.qcow2文件，因此我可以将其复制到其他版本上，然后它们就可以工作，但也会显示黑屏。
现在，当我输入“adb devices”命令时，我得到：

我在 CMD 中有这个：

您可以从以下几个方面来排查问题：
1.删除模拟器并创建一个新的模拟器，然后重试。
2.如果问题仍然存在，请重新检查您是否正确设置了Android SDK。
有关更多信息，请查看文档：为 Xamarin.Android 设置 Android SDK。
3.尝试修复你的视觉工作室。
