本文介绍了Flutter或Visual Studio Code不可见的Android虚拟设备(但在Android Studio中为“确定")的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

那里有很多类似的问题，但是它们都没有帮助(例如，

他们还建议设置环境变量 ANDROID_HOME 和/或 ANDROID_SDK_ROOT .我将两者设置为相同的值:

  C:\ Users \ me> dir％ANDROID_HOME％驱动器C中的卷是Windows卷序列号是FE0C-16F0C:\ Users \ me \ AppData \ Local \ Android \ sdk的目录17/06/2020 12:18< DIR>.17/06/2020 12:18< DIR>..19/06/2020 10:46< DIR>.downloadIntermediates20/06/2020 07:22 16 .knownPackages19/06/2020 10:47< DIR>.temp14/06/2020 13:15< DIR>构建工具17/06/2020 12:18< DIR>cmdline工具08/08/2020 13:53< DIR>仿真器08/06/2020 18:35< DIR>临时演员16/06/2020 12:50< DIR>执照08/08/2020 13:53< DIR>修补程序19/06/2020 10:47< DIR>平台工具08/06/2020 19:21< DIR>平台16/06/2020 12:59< DIR>皮肤08/06/2020 13:55< DIR>资料来源14/06/2020 13:15< DIR>系统映像08/06/2020 13:54< DIR>工具1个文件16个字节16个目录18,697,719,808字节免费C:\ Users \ me>

当我创建默认的Flutter应用时，Android Studio会向我显示VM作为运行/调试的选项:

但是 ，当我使用Visual Studio Code打开同一项目的文件夹(或其他任何文件夹)并运行时，它会在Chrome浏览器中启动，原因是:

  PS C:\ Users \ me \ AndroidStudioProjects \ flutter_app>颤振装置3个已连接的设备:Web服务器•Web服务器•Web Javascript•Flutter工具Chrome•chrome•网络JavaScript•Google Chrome 83.0.4103.106边缘•边缘•网络JavaScript•Microsoft Edge 83.0.478.54PS C:\ Users \ me \ AndroidStudioProjects \ flutter_app>

如何让Flutter识别我的Android虚拟机?

我可以看到每个文件在 c:\ Users \ me \ .android \ avd 中都有一个子目录.如何使Flutter意识到这一点?

为完整起见，这是Flutter doctor的输出:

  C:\ Users \ me> flutter doctor -v[√] Flutter(频道主版本为1.20.0-1.0.pre.132，在Microsoft Windows [版本10.0.18363.900]上，语言环境为en-GB)•Flutter版本1.20.0-1.0.pre.132，位于e:\ coding \ flutter•Framework修订版5995661777(8小时前)，2020-06-19 16:15:58 -0700•发动机修订版676cd566f7•Dart版本2.9.0(内部版本2.9.0-17.0.dev 7e72c9ae7e)[√] Android工具链-为Android设备开发(Android SDK版本29.0.3)•Android SDK位于C:\ Users \ me \ AppData \ Local \ Android \ sdk•平台android-R，构建工具29.0.3•ANDROID_HOME = C:\ Users \ me \ AppData \ Local \ Android \ sdk•ANDROID_SDK_ROOT = C:\ Users \ me \ AppData \ Local \ Android \ sdk•Java二进制文件位于:E:\ coding \ Android_studio \ jre \ bin \ java•Java版本OpenJDK运行时环境(内部版本1.8.0_242-release-1644-b01)•接受所有Android许可.[√] Chrome-为网络开发•Chrome浏览器位于C:\ Program Files(x86)\ Google \ Chrome \ Application \ chrome.exe[√] Android Studio(4.0版)•位于E:\ coding \ Android_studio的Android Studio•Flutter插件版本46.0.2•Dart插件版本193.7361•Java版本OpenJDK运行时环境(内部版本1.8.0_242-release-1644-b01)[√]已连接的设备(3个可用)•Web服务器•Web服务器•Web-javascript•Flutter工具•Chrome•chrome•web-javascript•Google Chrome 83.0.4103.106•边缘•边缘•网络JavaScript•Microsoft Edge 83.0.478.54•找不到问题！C:\ Users \ me>

这很有趣:当我在Android Studio中运行Flutter应用程序时，其虚拟机突然在Flutter/Visual Studio代码中可见:

PS C:\ Users \ me \ AndroidStudioProjects \ flutter_app>颤振装置 4 个已连接的设备:

当我在Android Studio中停止该设备时，Flutter无法再看到它.

解决方案

我高度建议您使用Git安装Flutter，然后在Android Studio中安装Android SDK.不要忘记将Flutter/bin添加到PATH.然后在Android Studio中创建您的虚拟设备，它应该显示在Visual Studio代码和控制台中.

There are many similar questions out there, but none of them help (for instance, this question is well upvoted, with a well upvoted answer, and would seem to be a dupe. BUT like others who commented there, the answer did not help me (also, the answer is 2 years old, which is an eternity on Flutter)).

At most, they tell how to add an Android VM in Android Studio. I have done so:

They also suggest setting the environment variables ANDROID_HOME and/or ANDROID_SDK_ROOT. I have set both to the same value:

C:\Users\me>dir %ANDROID_HOME%
 Volume in drive C is Windows
 Volume Serial Number is FE0C-16F0

 Directory of C:\Users\me\AppData\Local\Android\sdk

17/06/2020  12:18    <DIR>          .

C:\Users\me>

When I create the default Flutter app, Android Studio shows me the VMs as an option for run/debug:

BUT, when I open that same project's folder (or any other) with Visual Studio Code and run, it launches in the Chrome browser, because:

PS C:\Users\me\AndroidStudioProjects\flutter_app> flutter devices
3 connected devices:

Web Server • web-server • web-javascript • Flutter Tools
Chrome     • chrome     • web-javascript • Google Chrome 83.0.4103.106
Edge       • edge       • web-javascript • Microsoft Edge 83.0.478.54
PS C:\Users\me\AndroidStudioProjects\flutter_app>

How do get Flutter to recognize my Android virtual machines?

I can see that each has a sub-directory in c:\Users\me\.android\avd. How do I make Flutter aware of it?

Here's the output of Flutter doctor, for completeness:

C:\Users\me>flutter doctor -v

This is interesting: when I run a Flutter app in Android Studio, its VM suddenly becomes visible in Flutter/Visual Studio Code:

PS C:\Users\me\AndroidStudioProjects\flutter_app> flutter devices 4 connected devices:

sdk gphone x86 arm • emulator-5554 • android-x86 • Android 11 (API 30) (emulator) Web Server • web-server • web-javascript •
Flutter Tools Chrome • chrome • web-javascript •
Google Chrome 83.0.4103.106 Edge • edge •
web-javascript • Microsoft Edge 83.0.478.54 PS
C:\Users\me\AndroidStudioProjects\flutter_app>

When I stop the device in Android Studio, Flutter can no longer see it.

解决方案

I highly suggest that you use Git to install Flutter, then install the Android SDK with Android Studio. Don't forget to add Flutter/bin to your PATH. Then create your Virtual Device in Android Studio and it should show up in Visual Studio Code and the console.
