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。

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

我认为通过终端到达的最佳方式是:

cd ~/Library/Android/sdk/emulator

或者对于Windows:

cd %userProfile%\AppData\Local\Android\sdk\emulator

直接运行某个AVD:

./emulator -avd {AVD_NAME}

列出你的avd使用:

./emulator -list-avds

不建议使用android create avd命令。现在建议使用avdmanager来代替从命令行启动模拟器。

首先，如果模拟器不存在，创建一个新的模拟器:

avdmanager create avd --name "MyEmulator" -k "system-images;android-
26;google_apis;x86"

这里假设您已经安装了一个与API 26匹配的X86系统映像，并安装了谷歌API。

然后，您可以使用emulator @MyEmulator启动模拟器。

转到模拟器所在的目录

美元{ANDROID_SDK} -工具-模拟器

从CLI检查模拟器列表

模拟器-list-avds

从列表中提取AVD

-avd模拟器{avd_name}
