Question

我已经从模板创建了一个Blank（或Master-Detail，或Tabbed-无关紧要）Xamarin.Forms项目。该项目已在Visual Studio中加载，我尝试以Debug模式（使用Android_Accelerated_x86_Oreo(Android 8.1 - API 27)）运行它，但失败。

这是“输出”窗口：

我不了解Xamarin.Forms的第一件事-我只是将脚趾放在这里，默认项目甚至无法运行。

修改

我试图通过在适当的目录中运行emulator.EXE -partition-size 512 -no-boot-anim -verbose -feature WindowsHypervisorPlatform -avd Android_Accelerated_x86_Oreo -prop monodroid.avdname=Android_Accelerated_x86_Oreo来手动运行仿真器，并在很长的输出流的底部出现了此错误：

qemu-system-x86_64.exe: WHPX: Failed to create partition, hr=80070005
failed to initialize WHPX: Invalid argument
emulator: Done with QEMU main loop
emulator: User-config was not changed.

如果有人认为有帮助，我可以附加完整的输出。

**编辑2 **

我试图使用设备管理器启动仿真器，并且在启动时我得到了这个提示：

Answer 1

此问题与Xamarin无关，如果创建本机Android应用程序，则会在Windows 10计算机上遇到相同的问题。

这是一个已报告给Google和Microsoft的“错误”。

似乎是用户权限问题。以管理员身份运行Visual Studio或手动制作的命令应该可以解决该问题。

Answer 2

咨询了一些Xamarin专家之后，最简单的解决方法是转到工具-> Android-> Android设备管理器，然后编辑设备定义以删除Google Play商店：

我尝试了一下，一切都变得像魅惑一样。

Xamarin.Forms项目不会启动Android模拟器
