Android studio 3.0上进行多渠道打包遇到的问题小结(超简洁版)

error:all flavors must now belong to a named flavor dimension. the flavor 'xiaomi' is not assigned to a flavor dimension. learn more at https://d.android.com/r/tools/flavordimensions-missing-error-message.html

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：

解决问题参考：

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] 
 } 

然后解决问题之后我又去官网查阅了一下，地址如下：

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

总结
