在build.gradle文件android节点下配置

productFlavors {
        htd {}
        htk {}
    }

    android.applicationVariants.all { variant ->
        variant.outputs.all {
            outputFileName = "钢筋笼${defaultConfig.versionName}_${releaseTime()}_${variant.productFlavors[0].name}.apk"
        }
    }
static def releaseTime() {
    return new Date().format("yyyy-MM-dd", TimeZone.getTimeZone("UTC"))
}

不同渠道使用不同lib，先去掉implementation fileTree(dir: 'libs', include: ['*.jar'])
然后添加指定lib 格式 渠道名+Implementation 如下

htdImplementation files('libs/380d_mtk6755_jar_v1.0.jar')
htkImplementation files('libs/Jb380_Common_V1.3.jar')

当遇见All flavors must now belong to a named flavor dimension..错误时在defaultConfig节点配置flavorDimensions "versionCode"
如下：

defaultConfig {
        applicationId "com.ohoyee.steelQualityInspection"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode 2
        versionName "1.1"
        flavorDimensions "versionCode"
        multiDexEnabled true
    }
