android：Fail to resolve support-

https://github.com/wonday/react-native-pdf ,下载这个项目的example项目跑，一直报

android：

Fail to resolve support-media-cpmpat

Fail to resolve support-utils 等等，

后来看了网上说，把google配置放在最前面就可以了。亲测，果然有用。

allprojects {

repositories {

maven {

url'https://maven.google.com/'

            name'Google'

        }

google()

mavenLocal()

jcenter()

maven {

// All of React Native (JS, Obj-C sources, Android binaries) is installed from npm

            url"$rootDir/../node_modules/react-native/android"

        }

//        maven {

//            url 'https://dl.google.com/dl/android/maven2/'

//            name 'Google'

//        }

    }

}
