Windows 10对我的帮助:

1 cd C:\Users\xxx\AppData\Local\Android\Sdk\emulator

列出所有可用的:emulator -list-avds

3启动NON-GUI模式:模拟器-avd Pixel_3a_API_30_x86 -no-window

如果您严格地试图从命令行运行模拟器，请在OSX中尝试此操作。

"/Applications/Android Studio.app/sdk/tools/emulator" -avd <NAMEOFDEVICE> -netspeed full -netdelay none

您可以通过向.bash_profile添加别名并将其发送到后台作业来简化它。

alias android='/Applications/Android\ Studio.app/sdk/tools/emulator <NAMEOFDEVICE> -netspeed full -netdelay none &'

让Bash知道这些变化。

source ~/.bash_profile

打开命令提示符，进入<android-Home>\sdk\tools>emulator -avd <AVD_NAME>

这里“emulator”是用来打开Android虚拟设备的命令。

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.

对于一键式(BATCH文件)启动，这是我所做的:

从Android Studio -> Tools -> AVD Manager ->点击箭头向下，选择查看详细信息(对我来说是Pixel_2_API_28，所以下面相应地更改) 创建一个start.bat文件，并将以下内容放入其中:

c: cd C:\Program Files (x86)\Android\ android-sdk\emulator\ 模拟器-avd Pixel_2_API_28

解释:

第一行:对我来说是必要的，因为我从d启动它: 第二行:对我来说，没有使用工具\模拟器 第三行: 确保你用你的名字更改了AVD的名字 Pixel_2_API_28)

使用:

从命令行启动start.bat

在Mac(我认为还有Linux)上，创建AVD后，你可以创建一个别名: alias run-android='~/Library/Android/sdk/tools/emulator -avd ${YOUR_AVD_NAME} &'

注意:别名的执行不会锁定你的终端，如果你想这样做，只需删除最后一个'&'。

运行模拟器它自己会给你一个错误，因为他期望，在你当前的位置，你有:/emulator/qemu/${YOUR_PATFORM}/qemu-system-x86_64'来启动模拟器。
