    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

build.gradle

apply from: "config.gradle"

config.gradle

ext {
        android = [
                compileSdkVersion: 27,
                applicationId    : "com.bwie.test.shoppingcart",
                minSdkVersion    : 15,
                targetSdkVersion : 27,
                versionCode      : 1,
                versionName      : "1.0"
        ]
    
        dependencies = [

        ]
    }

![70][]

完了之后在 build.gradle 里加入这一行代码：（意思是在这个项目中引用的意思）

apply from: "config.gradle"

![70 1][]

最后在导入以下依赖：
