执行ionic cordova build android 或ionic cordova run android 时，突然就报错：You have not accepted the license agreements of the following SDK components。
折腾半天最后
解决方法：
卸载及重装android 平台：
ionic cordova platform rm android
ionic cordova platform add android
Ionic 安卓打包或运行报错：You have not accepted the license agreements of the following SDK components
