1.在工程的根目录下创建一个config.gradle的文件

ext {
    plugins = [
            application: 'com.android.application',
    ]

    android = [
            applicationId    : "com.mvpframe",
            compileSdkVersion: 25,
            buildToolsVersion: "25.0.3",

            minSdkVersion    : 14,
            targetSdkVersion : 25,

            versionCode      : 1,
            versionName      : "1.0",

            testInstrumentationRunner : "android.support.test.runner.AndroidJUnitRunner"
    ]

    bintray = [

    ]

    dependencies = [
            appCompat            : 'com.android.support:appcompat-v7:25.3.1',
            constraint           : 'com.android.support.constraint:constraint-layout:1.0.0-alpha7',
            junit           : 'junit:junit:4.12',
//            design             : 'com.android.support:design:25.3.1',
//            cardView           : 'com.android.support:cardview-v7:25.3.1',
//            recyclerView       : 'com.android.support:recyclerview-v7:25.3.1',
//            loading            : 'com.yanzhenjie:loading:1.0.2',
//            swipeRecyclerView  : 'com.yanzhenjie:recyclerview-swipe:1.1.4'
    ]
}

2.在根目录下的build.gradle中加入,该项目能使用config.gradle这个文件。

apply from: "config.gradle"

3.在使用项目中的build.gradle中版本配置，SDK配置，依赖配置

apply plugin: rootProject.ext.plugins.application

android {

    compileSdkVersion rootProject.ext.android.compileSdkVersion
    buildToolsVersion rootProject.ext.android.buildToolsVersion

    defaultConfig {

        applicationId rootProject.ext.android.applicationId
        minSdkVersion rootProject.ext.android.minSdkVersion
        targetSdkVersion rootProject.ext.android.targetSdkVersion
        versionCode rootProject.ext.android.versionCode
        versionName rootProject.ext.android.versionName

        testInstrumentationRunner rootProject.ext.android.testInstrumentationRunner
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    compile rootProject.ext.dependencies.appCompat
    compile rootProject.ext.dependencies.constraint

    testCompile rootProject.ext.dependencies.junit
}
