问题
我正在尝试制作一个 Cordova 插件。我所做的是：
$ cordova create toasty-plugin-test com.stanleyidesis.toastyplugintest ToastyPluginTest
$ cd toasty-plugin-test
$ cordova platforms add android
$ cordova requirements
然后出现了下面的错误：
[boy@Plum toasty-plugin-test ]$ cordova requirements
android 的要求检查结果：
Java JDK：已安装 15.0.1
Android SDK：已安装 true
Android 目标：未安装
命令以退出代码 1 失败：avdmanager list target
