找到 sdk/emulator.exe, 复制路径

~\emulator.exe -netdelay none -netspeed full -avd Nexus_5x_API_28

保存为.bat 批处理文件 打开.bat 文件可以打开虚拟机

  1. （更简单的方法不用创建.bat 文件）点一下右下角 No Device ， 选择虚拟机或者创建虚拟机（创建虚拟机需要 AVD system image， 可以通过Android studio 安装，也可以通过sdk manager 直接安装）

  2. Android studio => tools => add device => add os
