打开CMD 获取所有模拟器列表(C:\Users\DJango\AppData\Local\Android\sdk\ Emulator > Emulator -list-avds) 选择任何模拟器 (C:\Users\DJango\AppData\Local\Android\sdk\emulator>emulator -avd Pixel_2_API_28)

在windows中，我使用这个PowerShell脚本来启动它。

$em = $env:USERPROFILE+"\AppData\Local\Android\sdk\tools\emulator.exe"; 
Start-Process $em " -avd Nexus_5X_API_24" -WindowStyle Hidden;

我假设你已经构建了你的项目，只需要启动它，但你没有创建任何avd，必须使用命令行进行所有操作。你必须做以下事情。

Create a new virtual device (AVD) for the platform you need. If you have to use command line for creating your AVD, you can call android create avd -n <name> -t <targetID> where targetID is the API level you need. If you can use GUI, just type in android avd and it will launch the manager, where you can do the same. You can read more about AVD management through GUI and through command line. Run the AVD either by using command emulator -avd <name> or through previously launched GUI. Wait until the emulator fully loads, it takes some time. You can read about additional options here. Now you have to install the application to your AVD. Usually during development you just use the same Ant script you used to build the project, just select install target. However, you can install the application manually using command adb install <path-to-your-APK>. Now switch to emulator and launch your application like on any normal device, through the launcher. Or, as an alternative, you can use the following command: adb shell am start -a android.intent.action.MAIN -n <package>/<activity class>. For example: adb shell am start -a android.intent.action.MAIN -n org.sample.helloworld/org.sample.helloworld.HelloWorld. As a commenter suggested, you can also replace org.sample.helloworld.HelloWorld in the line above with just .HelloWorld, and it will work too.

Windows:

在Windows搜索栏中搜索环境，选择“编辑系统环境变量” 在“系统属性”窗口中，单击“环境变量”并指定PATH环境变量的值:

C：\Users\{USER}\AppData\Local\Android\Sdk\emulator.

现在打开CMD或Powershell，输入: 模拟器-list-avds 这将显示所有avd的列表。 要运行特定的AVD，在CMD/Powershell中输入:emulator -avd {EmulatorName}

如果您添加了正确的android模拟器路径，AVD将打开。

列出所有已安装的设备:emulator -list-avds

这将列出安装在Android Studio中的所有设备。

运行模拟器:emulator -avd device_name

例如，如果你在运行选项1中的命令后得到了Pixel_3a_API_30_x86，那么你运行模拟器的命令将是:emulator -avd Pixel_3a_API_30_x86

打开CMD

打开命令提示符 在我的例子中输入模拟器的路径

C: \ adt - bundle - windows - x86_64 - 20140702 \ \ sdk工具

在我的例子中写“emulator -avd emulatorname”
