你应该添加AVD模拟器。 去这个位置:

C:\Users\%username%\AppData\Local\Android\sdk\

启动AVD管理器，在第二个选项卡(设备定义)中单击“创建AVD”按钮。

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。

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

我也有同样的问题。我删除了。android/avd文件夹中的图像模拟器，在我安装lib32stdc++6后:

sudo apt-get install lib32stdc++6

所以，它起作用了!魔法吗?

/usr/local/share/android-sdk缺少平台目录。 我创建了一个名为平台的空目录来解决这个问题。

这意味着您使用工具的路径不正确。这是它在mac上使用brew的样子。注意版本。

export ANDROID_SDK_ROOT='/usr/local/Cellar/android-sdk/24.4.1_1'

在你的情况下，看起来你应该运行这个:

export ANDROID_SDK_ROOT='/Users/username/Library/Android/sdk'
