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。

打开终端，然后

cd path_to/Android/Sdk/emulator

并运行以下命令来获取您在使用android studio之前创建的模拟器名称

./emulator -list-avds

将$emulator_name替换为您想要启动和运行的

./emulator -avd $emulator_name

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

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

(仅适用于Windows) 为什么要折磨自己?制作一个简单的BAT文件!：

打开记事本 创建如下所示的命令 保存为*.bat (可选)创建*.bat的快捷方式，重命名快捷方式并更改图标

命令如下:

cd /d你的cd

例子:

cd /d d:\Android_SDK\emulator && emulator -avd Nexus_5_API_28

假设您已经正确安装了Android studio，打开命令提示符并键入 Emulator -list-avds将显示所有设备，然后输入Emulator @avd_name，其中avd_name是安装的模拟器的名称。
