让它在Windows 10上工作:

C:\Users\UserName\AppData\Local\Android\Sdk\tools>emulator -list-avds
Nexus_5X_API_28
C:\Users\UserName\AppData\Local\Android\Sdk\emulator>emulator -avd Nexus_5X_API_28

列出您拥有的模拟器

~/Library/Android/sdk/tools/emulator -list-avds

例如，我有这个Nexus_5X_API_24

运行模拟器的命令是

cd ~/Library/Android/Sdk/tools && ./emulator -avd Nexus_5X_API_24

以下是你需要做的:

1.Download and extract the SDK. 2.Open a terminal and navigate to the “tools” directory. 3.Launch the “android” tool (./android if you are currently in the tools directory). 4.Tick off the “SDK Platform” for each version of Android that you’d like to use in your emulator. 5.Click the “Install N Packages” button. 6.Click each package and tick off “Accept License” (legally, I’m probably required to tell you that this step may take several hours as you read each license ;). 7.Done with those licenses? Great. Click “Install”. Wait for the SDK manager to finish installing your packages, then you can close it. 8.Back in your terminal, still in the tools directory, enter ./android avd which will launch the Android Virtual Device Manager. 9.Click “New” and fill out the form to build the device you’d like to emulate. In the “Target” dropdown, you’ll see the SDK Platforms that you installed earlier. If the version you need is missing, you need to go back and install it. Click OK when you’re done. 10.Click on the device that you just created and click the “Start” button, tweak any options that you need on the Launch Options window, and click “Launch”.

也检查一下这个问题的答案。

在Ubuntu 20.04中，我找到了以下解决方案

首先你需要导出Android路径变量。为此:

export ANDROID_SDK=~/Android/Sdk
export PATH=$ANDROID_SDK/emulator:$ANDROID_SDK/tools:$PATH

根据您的安装路径不同，路径可能会有所变化。如果Android Studio是使用Ubuntu软件安装的，那么路径将与上面所述相同。

如果导出工作正常，那么下面的命令应该列出您的AVD名称。

emulator -list-avds

在我的例子中，我得到了结果

Nexus_5_API_30

这是我的AVD的名字。

如果上面的命令列出了您的AVD名称，那么您可以通过以下方式运行您的AVD:

emulator @YOUR_AVD_NAME

对我来说

emulator @Nexus_5_API_30

您可以将导出命令添加到.bashrc文件中，以避免每次需要运行AVD时都输入导出命令。

我正在做一个React Native项目，我也遇到了这个问题

我在桌面上制作了一个可以快速打开的.bat文件，解决了这个问题

.bat文件的内容是

C:\Users\haria\AppData\Local\Android\sdk\emulator\emulator -avd Pixel_2_XL_API_27

haria是我的Windows用户名和 Pixel_2_XL_API_27是我的模拟器名称

如果您想查看模拟器名称，请打开CMD(或PowerShell)并键入(在Windows中)

cd C:\Users\haria\AppData\Local\Android\sdk\emulator

然后查看模拟器的名称

。/模拟器-list-avds

在MacOS

首先列出已安装的模拟器

~/Library/Android/sdk/tools/emulator -list-avds

然后运行模拟器

~/Library/Android/sdk/tools/emulator -avd Nexus_5X_API_27
