因为国内Android市场渠道众多，为了统计每一个渠道的下载以及数据统计，须要我们针对每一个渠道进行单独打包，而Gradle能够帮助我们完毕自己主动多渠道打包。

一多渠道打包流程

(1) 在AndroidManifest.xml中配置PlaceHolder

<meta-data

    android:name="UMENG_CHANNEL"

    android:value="${UMENG_CHANNEL_VALUE}" />

(2) 在build.gradle中配置producFlavors

android {

    productFlavors {

        xiaomi {

            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "xiaomi"]

        }

        _360 {

            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "_360"]

        }

        baidu {

            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "baidu"]

        }

        wandoujia {

            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "wandoujia"]

        }

    }

}

或者批量改动

android {

    productFlavors {

        xiaomi {}

        _360 {}

        baidu {}

        wandoujia {}

    }  

    productFlavors.all {

        flavor -> flavor.manifestPlaceholders = [UMENG_CHANNEL_VALUE: name]

    }

}
