react-native 报错 Checking the license for package Android SDK Build-Tools 23.0.1Checking the license

react-native run-android时可能会报下面错误：

Checking the license for package Android SDK Build-Tools 23.0.1 in XXX
You have not accepted the license agreements of the following SDK components: XXX

错误的原因就很明显，没有accepted license

解决方法：cmd cd到sdk的bin路径下，执行

sdkmanager.bat --licenses

然后会出现 y/n?的提示，一路y下去就行了
