在终端中输入cordova运行android后，我得到了这个错误:
Waiting for emulator to start...
PANIC: Broken AVD system path. Check your ANDROID_SDK_ROOT value [/Users/username/Library/Android/sdk]!
这发生在导出之后:
export ANDROID_SDK_ROOT='/Users/username/Library/Android/sdk'
在导出之前，我得到:
Waiting for emulator to start...
PANIC: Cannot find AVD system path. Please define ANDROID_SDK_ROOT
你知道我哪里错了吗?我确定这是sdk根，所以为什么我得到破碎的avd系统路径?

要修复或避免此问题，请确保:
You have an environment variable ANDROID_SDK_ROOT pointing to a root folder of android sdk. You have a correct file structure in the sdk folder. cmdline-tools, emulator, platform-tools, system-images, platforms should be present. If you don't have these folders you should install missing components. emulator is the emulator itself. system-images has iso images of OS to run in the emulator. platforms has platform packages required to compile an app for different APIs. platform-tools has adb and other necessary tools. Without these components the emulator wont start and will post the same error about broken avd path. Make sure that you downloaded through sdkmanager matching api versions of system image and platform. e.g. for API-30 platforms;android-30 and system-images;android-30;default;x86_64. Make sure that your avd devices are located in HOME/.android/avd. If you have custom location for avd devices you should create one more environment variable ANDROID_AVD_HOME pointing to /avd/ folder.
本文提供了所有环境变量的信息，但除了ANDROID_SDK_ROOT和ANDROID_AVD_HOME，你不需要任何其他的环境变量。

我用的是Windows 10，问题是我电脑中的avd目录中有非ascii字符。
下面是该怎么做:
以管理员身份运行cmd
执行如下命令:
mklink /D C:\\.android C:\\Users\\-yourUsername-\\.android
(这将在非ascii字符的路径和新路径之间创建一个符号链接)
在环境变量中添加值为C的ANDROID_AVD_HOME变量:\\.android\avd。

我下载了一个新的模拟器，在我的Mac电脑上解决了这个问题。
删除早期创建的设备。 关闭Android工作室。 打开:控制面板->系统和安全->系统->高级系统设置-> 环境变量。 创建新变量ANDROID_SDK_HOME并设置 新路径(在我的情况下，它是F:\Coding2019\Android\AVDdevices)。推动“ok”。 打开Android Studio。 创建新设备。在下拉菜单中创建完成后，点击“查看详细信息”可以看到新AVD的新路径。
我在Windows 10上就遇到过这个问题。 我尝试了几种解决办法，但没有一个奏效。 以下是我解决问题的方法:
Uninstalled Android Studio, SDK, .android and .AndroidStudio folders in %USERPROFILE%, Android folder in %LOCALAPPDATA%. Uninstalled Java. Downloaded latest Java JDK:https://www.oracle.com/technetwork/java/javase/downloads/jdk13-downloads-5672538.html and set PATH Environment Variable: https://docs.oracle.com/en/java/javase/11/install/installation-jdk-microsoft-windows-platforms.html#GUID-96EB3876-8C7A-4A25-9F3A-A2983FEC016A I created new Windows 10 local user using LATIN CHARACTERS with admin priviledges. Switched to the new user and installed Android Studio. When the setup wizard was shown, I selected Custom option and checked Android emulator to be installed. I left all location folders as DEFAULT.
现在我的新用户帐户一切正常。
