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。

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。

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.

使用dns帮助从命令行启动模拟器

模拟器程序位置:/Users/{{UserName}}/Library/Android/sdk/tools

检查现有avd:- 模拟器-list-avds 启动模拟器，设置dns /Users/{{UserName}}/Library/Android/sdk/tools/emulator -avd Pixel_API_26 -dns-server 8.8.8.8

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”

-avd阿迪vd模拟器
