由于国内Android市场渠道众多，为了统计每个渠道的下载以及数据统计，需要我们针对每个渠道进行单独打包，而Gradle可以帮助我们完成自动多渠道打包。

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"]        }    }  }

或者批量修改

android {      productFlavors {        xiaomi {}        _360 {}        baidu {}        wandoujia {}    }      productFlavors.all {         flavor -> flavor.manifestPlaceholders = [UMENG_CHANNEL_VALUE: name]     }}
