"Could not find mandroid!" VS 社区 xamarin
"Could not find mandroid!" VS Community xamarin
我刚刚下载了包含 Xamarin 4.0.3214 的 VS 社区，当我创建一个空的 android 项目然后尝试构建它时，我收到以下错误和警告：
Could not find mandroid!
The referenced component 'System.Core' could not be found.
The referenced component 'System.Xml.Linq' could not be found.
和其他类似错误。
我尝试删除 xamarin 并重新安装它，但没有成功。
更新：
当我按照建议检查日志时，我发现了一些错误：

请检查您的系统中是否存在以下所有文件：
%ProgramFiles(x86)%\MSBuild\Xamarin\Android\Mono.Android.DebugRuntime-debug.apk%ProgramFiles(x86)%\MSBuild\Xamarin\Android\Ionic.Zip.dll%ProgramFiles(x86)%\MSBuild\Xamarin\Android\mandroid.exe%ProgramFiles(x86)%\Reference Assemblies\Microsoft\Framework\MonoAndroid\v1.0\mscorlib.dll
如果其中任何文件丢失，您可以尝试完全卸载并重新安装：
- 从 "Programs and Features" 控制面板卸载 "Xamarin" 软件包。
手动删除以下 2 个文件夹（如果其中一个仍然存在）：
%ProgramFiles(x86)%\MSBuild\Xamarin\Android%ProgramFiles(x86)%\Reference Assemblies\Microsoft\Framework\MonoAndroid
- 重新安装 Xamarin。
如果在完全卸载、重新安装和重新启动后，第 1 步中的任何文件仍然丢失，最好检查任何您的病毒防护软件 运行 看看它是否可以隔离丢失的文件。
作为另一种可能的解决方法，您可以尝试从 Xamarin.VisualStudio .msi 文件中手动提取丢失的文件。特别是，您可以使用 msiexec 命令和 TARGETDIR 属性 将 .msi 提取到临时文件夹（请参阅 ), and then copy the files from that temporary folder to their proper install locations. If you don't have a copy of the .msi, you can download it from your account page as illustrated under "Download Links" on https://kb.xamarin.com/customer/portal/articles/1699777.
The referenced component 'System.Core' could not be found.
The referenced component 'System.Xml.Linq' could not be found.
这些消息有时会显示为与 "Could not find mandroid!" error/warning 无关的单独警告。出现这些消息的最常见原因之一是找不到 Android SDK 或 Java SDK。为了帮助排除这种可能性，请确保在 Tools > Options > Xamarin > Android Settings.
下两条路径都显示有绿色复选标记
尝试其他步骤
如果上述步骤中的 none 有帮助（例如，如果所有预期的文件都 存在 但您仍然收到 "Could not find mandroid!" 消息），您可以检查日志文件以获取可能的其他线索：
Select 帮助 > Xamarin > 打开日志... 在 Visual Studio.
检查最近的 *Ide.log 和 monodroid*.log 个文件。
我刚刚下载了包含 Xamarin 4.0.3214 的 VS 社区，当我创建一个空的 android 项目然后尝试构建它时，我收到以下错误和警告：
Could not find mandroid!
The referenced component 'System.Core' could not be found.
The referenced component 'System.Xml.Linq' could not be found.
和其他类似错误。
我尝试删除 xamarin 并重新安装它，但没有成功。

Could not find mandroid!
请检查您的系统中是否存在以下所有文件：
%ProgramFiles(x86)%\MSBuild\Xamarin\Android\Mono.Android.DebugRuntime-debug.apk%ProgramFiles(x86)%\MSBuild\Xamarin\Android\Ionic.Zip.dll%ProgramFiles(x86)%\MSBuild\Xamarin\Android\mandroid.exe%ProgramFiles(x86)%\Reference Assemblies\Microsoft\Framework\MonoAndroid\v1.0\mscorlib.dll
如果其中任何文件丢失，您可以尝试完全卸载并重新安装：
- 从 "Programs and Features" 控制面板卸载 "Xamarin" 软件包。
手动删除以下 2 个文件夹（如果其中一个仍然存在）：
%ProgramFiles(x86)%\MSBuild\Xamarin\Android%ProgramFiles(x86)%\Reference Assemblies\Microsoft\Framework\MonoAndroid
- 重新安装 Xamarin。
如果在完全卸载、重新安装和重新启动后，第 1 步中的任何文件仍然丢失，最好检查任何您的病毒防护软件 运行 看看它是否可以隔离丢失的文件。
作为另一种可能的解决方法，您可以尝试从 Xamarin.VisualStudio
.msi文件中手动提取丢失的文件。特别是，您可以使用msiexec命令和TARGETDIR属性 将.msi提取到临时文件夹（请参阅 ), and then copy the files from that temporary folder to their proper install locations. If you don't have a copy of the.msi, you can download it from your account page as illustrated under "Download Links" on https://kb.xamarin.com/customer/portal/articles/1699777.

The referenced component 'System.Xml.Linq' could not be found.
这些消息有时会显示为与 "Could not find mandroid!" error/warning 无关的单独警告。出现这些消息的最常见原因之一是找不到 Android SDK 或 Java SDK。为了帮助排除这种可能性，请确保在 Tools > Options > Xamarin > Android Settings.
下两条路径都显示有绿色复选标记尝试其他步骤
如果上述步骤中的 none 有帮助（例如，如果所有预期的文件都 存在 但您仍然收到 "Could not find mandroid!" 消息），您可以检查日志文件以获取可能的其他线索：
Select 帮助 > Xamarin > 打开日志... 在 Visual Studio.
