用android studio多渠道打包

1. 官方教程

　　https://developer.android.com/studio/build/build-variants.html

2. 设置Build Types参数

打开 Project Sturcture --> Build Variatns --> Build Types

设置参数如:zipalign = true

3. 创建 dimension

进入第2个选项卡: Flavors 创建 dimension

4. 添加渠道,设置渠道参数

点 + 按钮 ---> 点 Add Product Flavor -- > 输入渠道名字 --> 设置渠道参数,如ProGuard Files.

5. 添加其它渠道

如上.添加完后,如下:

6. 设置生成apk的名字

module 的 build.gradle 文件

 apply plugin: 'com.android.application'

 apply plugin: 'org.greenrobot.greendao' // apply plugin

 apply plugin: 'com.jakewharton.butterknife'

 def buildTime(){

     return new Date().format("yyMMdd", TimeZone.getTimeZone("UTC"))

 }

 android {

     compileSdkVersion 28

     buildToolsVersion '28.0.3'

     defaultConfig {

         applicationId "cn.com.example.app"

         minSdkVersion 15

         targetSdkVersion 26

         versionCode 5

         versionName "v3.1.2.180103"

         testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

     }

     buildTypes {

         release {

             minifyEnabled false

             shrinkResources false

             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

             zipAlignEnabled = true

             applicationVariants.all { variant ->

                 variant.outputs.all { output ->

                     outputFileName = new File(

                         "${applicationId}_${variant.productFlavors[0].name}_${versionName}_${buildTime()}.apk".toLowerCase())

                 }

             }

         }

     }

     sourceSets { main { res.srcDirs = ['src/main/res', 'src/main/res/values-zh'] } }

     compileOptions {

         sourceCompatibility = '1.8'

         targetCompatibility = '1.8'

     }

     flavorDimensions 'channels'

     productFlavors {

         myapp {

             dimension = 'channels'

             minSdkVersion 22

             proguardFiles 'proguard-rules.pro'

         }

         huawei {

             dimension = 'channels'

             minSdkVersion 22

             proguardFiles 'proguard-rules.pro'

         }

         xiaomi {

             dimension = 'channels'

             minSdkVersion 22

         }

     }

 }

 dependencies {

     implementation fileTree(include: ['*.jar'], dir: 'libs')

     androidTestImplementation('androidx.test.espresso:espresso-core:3.1.0', {

         exclude group: 'com.android.support', module: 'support-annotations'

     })

     // add library

     //...

     implementation 'com.github.bumptech.glide:glide:4.9.0'

     annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'

 }

• buildTime()是个自定义函数,返回时间.
• "${applicationId}_${variant.productFlavors[0].name}_${versionName}_${buildTime()}.apk".toLowerCase() 包名_渠道名_版本名_时间.apk
