manifestPlaceholders = [UMENG_CHANNEL_VALUE: “umeng”] 可以设置 meta-data 中的value 数据，这个数据一般是用在渠道分发使用。

        main {
            //分模块存放资源

            ]
            manifest.srcFile 'src/main/AndroidManifest.xml'

        }
        //不同flavor的res目录    
        xiaomi.res.srcDirs = ['src/main/res-xiaomi']
        huawei.res.srcDirs = ['src/main/res-huawei']
        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('test')
        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.

        //debug.setRoot('build-types/debug')
        //release.setRoot('build-types/release')
}

//根据不同的Flavor和不同的module对App的资源进行替换和逻辑变换
//渠道Flavors，配置不同风格的app
productFlavors {
    xiaomi {

    }
    huawei{ //右键->Mark Directory as -> Resources Root

    }
}

//根据Flavor设置在清单文件中进行设置
productFlavors.all {
    flavor -> flavor.manifestPlaceholders = [UMENG_CHANNEL_VALUE: name, APP_NAME: name]
}

如果我们想在build的时候，就按照某种 flavor 进行打包，那么就可以在 Build Variants 中选择对应的 flavor 版本，然后正常编译即可编译出对应的apk。

按照Flavor打包成不同的apk

def releaseTime() {
    return new Date().format("yyyy-MM-dd", TimeZone.getTimeZone("UTC"))
}

android {
    ...
    android.applicationVariants.all { variant ->
      variant.outputs.all {
          //这里的逻辑是在配置阶段结束之后进行的
          outputFileName = "luckyboy-${variant.buildType.name}-${releaseTime()}-${defaultConfig.versionName}-${variant.productFlavors[0].name}.apk"
      }
  }
  ...
}

执行不同的命令得到不同的apk

./gradlew assemble

./gradlew assembleDebug

./gradlew assembleRelease

./gradlew assembleXiaomi

./gradlew assembleXiaomiRelease

将打包好的release包改名并拷贝到指定的地方，如下是将app/build/outputs目录下的编译好的apk文件拷贝到用户的桌面的release文件目录下，且按照 variant 归类。

android {

   ...
    afterEvaluate {
        applicationVariants.all { variant ->
                def name = variant.name // xiaomiRelease
                def baseName = variant.baseName //xiaomi-release
                println "name : $name" //
                println "baseName: $baseName"
                Map<String, String> map = System.getenv()
                String userName = map.get("USER")
                def des = '/Users/'+userName + '/Desktop/release'
                //根据apk类型打包（release 和 debug 两个版本，一般供单个应用打包使用）
                if (variant.buildType.name == 'release') {
                    println "release打包类型"
                    def output = variant.outputs.first()
                    def apkName = "app-${variant.baseName}"+"-${variant.versionName}.apk"
                    //修改打包的apk文件名称
                    output.outputFileName = apkName
                    println "outputFileName "+output.outputFile.name
                    println "outputFile----->"+output.outputFile.path
                    def destFilePath = des+"/"+"${variant.baseName}"
                    println "destFile----"+destFilePath
                    //拷贝apk 文件到指定的目录
                    copy {
                        from output.outputFile.path
                        into destFilePath
                    }
                }
                if (variant.buildType.name == 'debug'){ //Debug打包类型 构建的是debug包
                    println "debug打包类型"
                }
        }
    }
...

}

签名，在项目的app目录下创建keystore目录，然后 build->Generated Signed  Bundle/Apk，然后按照提示创建进签名文件，并进行相应配置，注意在 Create New的时候填写的是 keystore 的全路径【目录地址是keystore路径，包含文件的名称和后缀名，后缀名可以是jks】。

android {

  ...
  
 //signingConfigs的前后顺序不能乱
  signingConfigs {
        release {
            storeFile file("keystore/release.jks")
            storePassword "admin123"
            keyAlias "luckyjoy"
            keyPassword "admin123"
        }
        debug {
            storeFile file("keystore/debug.jks")
            storePassword "admin123"
            keyAlias "luckyjoy"
            keyPassword "admin123"
        }
    }  

  buildTypes {
        release {
            zipAlignEnabled true
            // 移除无用的resource文件 如果要使用shrinkResources 必须使minifyEnabled为true
            minifyEnabled true
            shrinkResources true
            signingConfig signingConfigs.release
            buildConfigField "boolean", "DEBUG_ENABLE", 'false'
            buildConfigField("String", "BASE_URL", '"http://one.luckyjoy.com"')
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            signingConfig signingConfigs.debug
            buildConfigField "boolean", "DEBUG_ENABLE", 'true'
            buildConfigField("String", "BASE_URL", '"http://one.luckyjoy.com"')
        }
    }

通过代码获取设置的渠道名称

val channel:String?
val appInfo = packageManager.getApplicationInfo(packageName, PackageManager.GET_META_DATA)
channel = appInfo.metaData.getString("UMENG_CHANNEL")
print("channel $channel")
tv_brand.text = channel

遇到的问题：

在项目执行 ./gradlew assemble 的时候，控制台报错 编译器 (1.8.0_144) 中出现异常错误。在查看其他的项目并进行对比之后，发现修改 compileSdkVersion 和 buildToolsVersion 以及 targetSdkVersion 之后【都修改成29，对应的buildToolsVersion 改成 29.0.2】，竟然神奇的好了，不清楚原因是什么，可能构建工具需要和对应的JDK版本要相匹配，否则也会出现问题。
