第一步：在清单文件AndroidManifest.xml中application模块中加入:

<meta-data
    android:name="UMENG_CHANNEL"
    android:value="${UMENG_CHANNEL_VALUE}"/>

第二步：在app的build.gradle中的android部分加入：

 flavorDimensions ""
    productFlavors{
        wandoujia{}
        xiaomi{}
        huaiwei{}
        oppo{}
        vivo{}
        meizu{}
        yingyongbao{}
    }
    productFlavors.all{
        flavor ->
            flavor.manifestPlaceholders =[UMENG_CHANNEL_VALUE : name]
    }
    applicationVariants.all{ variant ->
        variant.outputs.all{ output->
                    def outputFile = output.outputFile
                    if(outputFile!=null && outputFile.name.endsWith(".apk")){
                        def fileName = outputFile.name.replace(".apk","-${defaultConfig.versionName}.apk")
                        outputFileName = fileName
                    }

            }
    }

第三步：在示例ApplicationTest（在任何地方都可以）中获取meta-data

private String getChannel(){
        PackageManager pm = getPackageManager();
        ApplicationInfo applicationInfo = null;
        try {
            applicationInfo = pm.getApplicationInfo(getPackageName(), PackageManager.GET_META_DATA);
            return applicationInfo.metaData.getString("UMENG_CHANNEL");
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }
        return "";
    }

第四步：build ->Generate Signed Bundle or apk -> apk，打包apk

第五步：验证apk的渠道信息，
