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

假设你已经安装了Android Studio，并且SDK在你的PATH中，它是:

-avd avd_name模拟器

要获得AVD名称的列表，运行:

模拟器-list-avds

一张图胜过千言万语:)

如何从MAC终端启动AVD

你可以制作一个批处理文件，这将直接打开模拟器，而不需要打开Android Studio。如果你使用的是Windows:

Open Notepad New file Copy the next lines into your file: cd /d C:\Users\%username%\AppData\Local\Android\sdk\tools emulator @[YOUR_EMULATOR_DEVICE_NAME] Notes: Replace [YOUR_EMULATOR_DEVICE_NAME] with the device name you created in emulator To get the device name go to: C:\Users\%username%\AppData\Local\Android\sdk\tools Run cmd and type: emulator -list-avds Copy the device name and paste it in the batch file Save the file as emulator.bat and close Now double click on emulator.bat and you got the emulator running!

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”.
