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?
当前回答
按照下面的步骤，这将解决您的问题
1.
export ANDROID_HOME=/usr/local/Cellar/android-sdk/24.4.1
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$ANDROID_HOME/bin
2.
Go to android studio preferences => Build, Execution, Deployment => Build Tools => Gradle => Android studio => Enable embedded Maven Repository should be selected.
3.
Go to android studio preferences => Appearance & Behavior => System Settings => Android SDK => Go to SDK Tools and select Android Emulator

在Mac: 我使用brew和Android Studio安装了Android -sdk。不知何故，两次安装导致了这个问题。当我卸载我的brew安装的sdk使用brew桶卸载android-sdk，并添加以下vars到我的env。它工作。
export ANDROID_HOME=/Users/<Username>/Library/Android/sdk
export ANDROID_SDK_ROOT=$ANDROID_HOME
ANDROID_SDK_HOME是指向根目录的指针。该文件默认创建在“C:\Users\name\. android”目录下。android”，而不是你的SDK文件夹的根目录。然后: —将ANDROID_SDK_HOME分配到SDK根文件夹将无效。 -如果你的路”。“android”文件有非ascii字符，它将无法工作。 - AVD文件夹必须在您当前的”。android”文件。
所以答案是:
Change your SDK folder, if you need, like the previous answers (inside the project on Android Studio). Close Android Studio. Control Panel > System > Advanced System Settings > Environment Variables. Add a new User variable: Variable Name: ANDROID_SDK_HOME Variable Value: C:\src (or any folder that has not problems with non-ASCII characters or S.O. privileges) THE PATH THAT YOU WILL ENTER CANNOT BE ROOT FOLDER OF YOUR ANDROID SDK!!! Open Android Studio. Make sure a folder called ".android" was created in your new location. Delete the Android Virtual Device (AVD) that you created. Close and open Android Studio. Create a new AVD and see the magic happens.

我在mac os上运行模拟器时也有类似的问题。经过大量的斗争，我发现我在.bash_profile中设置了错误的sdk路径。我安装了两次android，它导致了这个问题。我设法修复通过匹配ANDROID_SDK_ROOT路径在.bash_profile与sdk，我在android工作室内使用。
我在Windows 10上运行Android Studio，在环境变量上设置ANDROID_HOME和ANDROID_SDK_ROOT，仍然得到错误。
结果发现，我忘了下载设备。
下载“丢失的系统映像”后，一切工作正常。
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。
