mac android studio 添加模拟器报错

emulator: ERROR: Unknown AVD name [Pixel_2_API_30], use -list-avds to
see valid list. HOME is defined but there is no file
Pixel_2_API_30.ini in $HOME/.android/avd (Note: Directories are
searched in the order $ANDROID_AVD_HOME, $ANDROID_SDK_HOME/avd and
$HOME/.android/avd)

是因为adnroid sdk home 为空 ，先找到adv 的位置

 找到adv 的位置 
/Users/xxx/.android/avd 
然后复制avd 文件夹 到
/Users/xxx/Library/Android/sdk

然后重启Android studio 就可以了
