Android 项目实例config.gradle配置

gradle支持自定义config.gradle,在GoogleSamples中提到我们必须使用关键字ext(对应ExtraPropertitesExtension的实例)来定义动态属性

*  **config.gradle**

--------------------

## config.gradle ##

在project根目录下自定义一个config.gradle，将一些配置信息及第三方依赖统一管理。代码如下

ext {
    //这里的ext是必须的
    
        android = [
                compileSdkVersion   : 25,
                buildToolsVersion   : '25.0.0',
                applicationId       : 'com.alpha.alphaapp',
                minSdkVersion       : 17,
                targetSdkVersion    : 25,
                versionCode         : 1,
                versionName         : 'v 1.1.0',
                defaultPublishConfig: 'release',
                publishNonDefault   : true
        ]
    
        dependencies = [
                "appcompat-v7"      : 'com.android.support:appcompat-v7:25.1.0',
                "support-design"    : 'com.android.support:design:+',
                "support-v4"        : 'com.android.support:support-v4:25.3.1',
                "roundedimageview"  : 'com.makeramen:roundedimageview:2.2.1',
                "Android-PickerView": 'com.contrarywind:Android-PickerView:3.2.5',
                "XTabLayout"        : 'com.androidkun:XTabLayout:1.1.1',
                "status-bar-compat" : 'com.githang:status-bar-compat:0.3',
                "recyclerview-v7"   : 'com.android.support:recyclerview-v7:23.2.0',
                "crashreport"       : 'com.tencent.bugly:crashreport:latest.release',
                "crashreport-native": 'com.tencent.bugly:nativecrashreport:latest.release',
    
                "junit"             : 'junit:junit:4.12',
                "volley"            : 'com.android.volley:volley:1.0.0',
                "okhttp"            : 'com.squareup.okhttp3:okhttp:3.2.0',
                "gson"              : 'com.google.code.gson:gson:2.8.0',
                "glide"             : 'com.github.bumptech.glide:glide:3.7.0',
                "rxandroid"         : 'io.reactivex:rxandroid:1.2.1',
                "rxjava"            : 'io.reactivex:rxjava:1.3.0'
    
        ]
    }

在app(module)目录下的build.gradle文件中使用如下配置:

apply plugin: 'com.android.application'
    
    
    android {
    
        //在android 标签下,唯一的属性就是compileSdkVersion,buildToolsVersion
    
        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 "android.support.test.runner.AndroidJUnitRunner"
        }
    
           ............
    
    dependencies {
        //当有很多包时,使用这个就是将所有libs下添加为依赖
        compile fileTree(include: ['*.jar'], dir: 'libs')
        androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
            exclude group: 'com.android.support', module: 'support-annotations'
        })
        testCompile rootProject.ext.dependencies["junit"]
        // 这里不需要添加这么多compile,第一行就是执行该操作的
        // compile files('libs/open_sdk_r5788_lite.jar')
        // compile files('libs/bottomView.jar')
        // compile files('libs/xUtils-2.6.14.jar')
        // //微信 记得后面修改为gradle模式
    
    
        //第三方依赖库
        compile rootProject.ext.dependencies["appcompat-v7"]
        compile rootProject.ext.dependencies["support-design"]
        compile rootProject.ext.dependencies["support-v4"]
        compile rootProject.ext.dependencies["roundedimageview"]
        compile rootProject.ext.dependencies["Android-PickerView"]
        compile rootProject.ext.dependencies["XTabLayout"]
        compile rootProject.ext.dependencies["status-bar-compat"]
        compile rootProject.ext.dependencies["okhttp"]
    
        //腾讯bugly日志
        compile rootProject.ext.dependencies["crashreport"];
        compile rootProject.ext.dependencies["crashreport-native"]
    
        //依赖其他两个library
        releaseCompile project(path: ':lib_sdk', configuration: 'release')
        releaseCompile project(path: ':lib_stub', configuration: 'release')
        debugCompile project(path: ':lib_sdk', configuration: 'debug')
        debugCompile project(path: ':lib_stub', configuration: 'debug')
    
    }

使用这种方式的好处是当Android Support Repository有更新时  
可以直接在gradle文件中展现提示,又有提示,又能统一管理依赖版本号,一举两得

注意：这里要在想使用这个config.gradle，我们要在project下的build.gradle中添加                         
      apply from : "config.gradle"

添加后build.gradle的代码如下：

apply from : "config.gradle"
    
    buildscript {
        repositories {
            jcenter()
           //是一个类似于github的代码托管仓库，声明了此配置，
           //可以轻松引用 jcenter上的开源项目
        }
        dependencies {
            classpath 'com.android.tools.build:gradle:2.2.0'
           //gradle是一个强大的项目构建工具，不仅可以构建Android，还可以构建java，C++等
           //此处引用android的插件
           // NOTE: Do not place your application dependencies here; they belong
           // in the individual module build.gradle files
        }
    }
    
    allprojects {
        repositories {
            jcenter()
        }
    }
    
    task clean(type: Delete) {
        delete rootProject.buildDir
    }

这样在library，app的build.gradle中使用依赖时，就可以如上面的方式进行依赖。
