插件安装失败

[daviscai]

工程用的是 ElemeFE/weex-vue-starter-kit ，weex-vue-starter-kit下执行 weexpack run android 是可以成功的，但安装插件失败，提示： Could not find gradle wrapper within Android SDK. 具体怎么解决？

$ weexpack plugin add nat-camera

解决了，

下载 https://dl.google.com/android/repository/tools_r25.2.3-windows.zip ,解压后，把 templates 文件夹复制到 C:\Users\xxx\AppData\Local\Android\sdk\tools\ ， 这个目录就是上面提示错误信息里最后一句 Looked here: 的目录

重新执行安装就可以了
