Detailed steps of Android multi-channel packaging

1. What is multi-channel packaging

There may be different statistical requirements in different application markets. It is necessary to release an installation package for each application market. Here comes the multi-channel packaging of Android. Add different logos in the installation package to distinguish various channels, so as to facilitate the statistics of various applications in the market.

2. Several packaging methods

3. Start using

3.1 Youmeng Umeng

Step 1: add in Android manifest

<Meta-data
 android:name="UMENG_CHANNEL"
 android:value="${channel}" />

Step 2: add Baidu {} in build.gradle as the abbreviation of the specified channel name

build {
 ......
 productFlavors {
 baidu {}
 xiaomi {}
 qihu360 {}
 yingyongbao {}
 huawei {}
 }
 productFlavors.all {
 flavor -> flavor.manifestPlaceholders = [UMENG_CHANNEL: name]
 }
}

Step 3: set the output APK name

Android studio version 2.3:

build {
 ......
 applicationVariants.all { variant ->
 variant.outputs.each { output ->
 def outputFile = output.outputFile
 if (outputFile != null && outputFile.name.endsWith('.apk')) {
  def fileName = "driver_${variant.productFlavors[0].name}_v${defaultConfig.versionName}.apk"
  output.outputFile = new File(outputFile.parent,fileName)
 }
 }
 }
}

Android studio version 3.0:

build {
 ......
 applicationVariants.all { variant ->
 variant.outputs.all {
 outputFileName = "driver_${variant.productFlavors[0].name}_v${variant.versionName}.apk"
 }
 }
}

If the following error occurs after gradle

You need to configure the dimension of flavor dimension to be the version number, so that all dimensions are unified

build {
 ......
 defaultConfig {
 ......
 flavorDimensions "versionCode"
 }
}

Step 4: compile and package

Build - generate signed bundle or APK - select release or debug

3.2 Android studio comes with

Android studio multi-modal packaging is the same as Youmeng packaging, but the name in the label < meta data > can be defined by itself and is not limited to "umeng_channel"

<Meta-data
 android:name="UMENG_CHANNEL" //可以随意定义
 android:value="${channel}" />

3.3 meituan walle

Step 1: configure the root build.gradle

buildscript {
 dependencies {
 classpath 'com.mcxiaoke.packer-ng:plugin:2.0.1'
 }
}

Step 2: configure app build.gradle

apply plugin: 'packer'
dependencies {
 ......
 implementation 'com.mcxiaoke.packer-ng:helper:2.0.1'
}

Step 3: plug in configuration

build {
 ......
 packer {
 archiveNameFormat = '${buildType}-v${versionName}-${channel}' // 定义输出APK名称
 archiveOutput = new File(project.rootProject.buildDir,"apks") // 设置APK输出目录
 channelFile = new File(project.rootDir,"channel.txt") // 添加渠道配置文件
 }
}

Step 4: create a new channel configuration file channel.txt

Create a new channel.txt file in the project root directory, as shown in the figure

The content of the document is the channel name. It is required that there must be one channel per line

Step 5: compile and package

Use the terminal command:

gradlew clean apkRelease

For reference: [official document of meituan multi-channel packaging]（ https://github.com/mcxiaoke/packer-ng-plugin )

4. Obtain channel information

1. How to obtain Youmeng and Android studio

By reading the < meta data > tag in the androidmanifest

private String getChannel() {
 try {
 　　PackageManager pm = getPackageManager();
 　　ApplicationInfo appInfo = pm.getApplicationInfo(getPackageName(),PackageManager.GET_Meta_DATA);
 　　String channel = appInfo.MetaData.getString(key); // key为<Meta-data>标签中的name
 　　if (!TextUtils.isEmpty(channel)) {
 　　return channel;
 　　}
　　} catch (Exception e) {
 　　e.printStackTrace();
　　}
　　return null;
}

2. Acquisition method of meituan walle

Meituan integrated self-contained acquisition method

private String getChannel() {
 try {
 　　PackageManager pm = getPackageManager();
 　　ApplicationInfo appInfo = pm.getApplicationInfo(getPackageName(),PackageManager.GET_Meta_DATA);
 　　String channel = appInfo.MetaData.getString(key); // key为<Meta-data>标签中的name
 　　if (!TextUtils.isEmpty(channel)) {
 　　return channel;
 　　}
　　} catch (Exception e) {
 　　e.printStackTrace();
　　}
　　return null;
}
