## android 多渠道打包 一： ##

常见开发中会有正式环境、测试环境两种配置，可以利用 gradle 进行简单配置，区分不同环境加载的配置

defaultConfig { 
            applicationId "com.example.cyf.kotlin"
            minSdkVersion 15
            targetSdkVersion 28
            versionCode 1
            versionName "1.0"
            flavorDimensions "cyf"  // 配置flavor 用于添加
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        }
    // 配置自己的渠道
     productFlavors { 
            guanwang {  dimension 'cyf' }
            guanwang2 {  dimension 'cyf' }
    
        }

根据环境更改自己配置，buildConfigField配置完成后可以通过 BuildConfig.XXX 找到对应的字段名

android.applicationVariants.all {  variant ->
        if(variant.flavorName == "guanwang"){ 
        // BuildConfig 类对应生成 public static int APP_FLAVOR_NAME = 1
            buildConfigField("int", "APP_FLAVOR_NAME", "1")
        } else if(variant.flavorName == "guanwang2") { 
            buildConfigField("int", "APP_FLAVOR_NAME", "2")
        }
        printf("\nversionName $variant.versionName")
        // 改版本名称
        variant.outputs.each {  output ->
            if (variant.buildType.name == "debug") { 
                output.versionNameOverride = variant.versionName + "t"
            }
        }
    
    }

### 如何使用android Studio 直接运行对应的渠道 ###

![打开Build variants][Build variants]

![选择对应的渠道][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZmX2ho_size_16_color_FFFFFF_t_70]  
对应生成BuildConfig类

public final class BuildConfig { 
      public static final boolean DEBUG = false;
      public static final String APPLICATION_ID = "com.example.cyf.kotlin";
      public static final String BUILD_TYPE = "release";
      public static final String FLAVOR = "guanwang";
      public static final int VERSION_CODE = 1;
      public static final String VERSION_NAME = "1.0";
      // Fields from the variant
      public static final int APP_FLAVOR_NAME = 1;
      // Fields from build type: release
      public static final boolean LOG_DEBUG = false;
    }
