Android studio 3.0上进行多渠道打包时编译时出现这个错误

多渠道打包参考：

多渠道打包的细节我就不说了，参考网络上的，或者我上面的这个链接就好，下面给出一下我修改的代码（如果有其他的改法也希望能多多交流）

flavorDimensions "default"
productFlavors {
    kuan {
        dimension "default"
        manifestPlaceholders = [UMENG_CHANNEL_VALUE: "kuan"]
    }
    xiaomi {
        dimension "default"
        manifestPlaceholders = [UMENG_CHANNEL_VALUE: "xiaomi"]
    }
    qh360 {
        dimension "default"
        manifestPlaceholders = [UMENG_CHANNEL_VALUE: "qh360"]
    }
    baidu {
        dimension "default"
        manifestPlaceholders = [UMENG_CHANNEL_VALUE: "baidu"]
   }
   wandoujia {
        dimension "default"
        manifestPlaceholders = [UMENG_CHANNEL_VALUE: "wandoujia"]
   }
}

或者：

flavorDimensions "default"
productFlavors {
    kuan {dimension "default"}
    xiaomi {dimension "default"}
    qh360 {dimension "default"}
    baidu {dimension "default"}
    wandoujia {dimension "default"}
}
productFlavors.all {
    flavor -> flavor.manifestPlaceholders = [UMENG_CHANNEL_VALUE: name]
}

根据官网说法：

You must assign each product flavor you configure to one of the flavor dimensions.

你必须指定一种 flavor dimensions

void flavorDimensions(String... dimensions)

flavorDimensions 后面可以添加多个不同类型的参数例如：

flavorDimensions "api", "mode"

接下来的使用对应起来就好了：

productFlavors {
demo {
    // Assigns this product flavor to the "mode" flavor dimension.
    dimension "mode"
    ...
}
full {
    dimension "mode"
    ...
}
// Configurations in the "api" product flavors override those in "mode"
// flavors and the defaultConfig {} block. Gradle determines the priority
// between flavor dimensions based on the order in which they appear next
// to the flavorDimensions property above--the first dimension has a higher
// priority than the second, and so on.
minApi24 {
    dimension "api"
    minSdkVersion '24'
    // To ensure the target device receives the version of the app with
    // the highest compatible API level, assign version codes in increasing
    // value with API level. To learn more about assigning version codes to
    // support app updates and uploading to Google Play, read Multiple APK Support
    versionCode 30000 + android.defaultConfig.versionCode
    versionNameSuffix "-minApi24"
    ...
}
minApi23 {
    dimension "api"
    minSdkVersion '23'
    versionCode 20000  + android.defaultConfig.versionCode
    versionNameSuffix "-minApi23"
    ...
}
minApi21 {
    dimension "api"
    minSdkVersion '21'
    versionCode 10000  + android.defaultConfig.versionCode
    versionNameSuffix "-minApi21"
    ...
}
}

好了，这就是官方给出的gradle多渠道打包的方式。
