Android several multi-channel packaging steps are how, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

1. What is multi-channel packaging

There may be different statistical requirements in different application markets, and it is necessary to release an installation package for each application market, which leads to the multi-channel packaging of Android. Add different logos to the installation package to distinguish each channel and facilitate the statistics of app in the market.

2. Several ways of packing

Friendly League UMeng Android Studio has its own Meituan Walle

3. Start using

3.1Friendship UMeng

Step 1: add to AndroidManifest

Step 2: add to build.gradle, and baidu {} is 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

The dimension that needs to be configured with flavor dimension is the version number, so that the dimensions are all 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 polymorphic packaging is the same as that of friends, but the name in the tag can be defined by itself and is not limited to "UMENG_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}'/ / define output APK name archiveOutput = new File (project.rootProject.buildDir, "apks") / / set APK output directory channelFile = new File (project.rootDir, "channel.txt") / / add Channel profile}}

Step 4: create a new channel profile channel.txt

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

The content of the file is the channel name, which requires that there must be one channel per line.

Step 5: compile and package

Use the Terminal command:

Gradlew clean apkRelease

For more information, please see [Meituan's official document for Multi-Channel Packaging] (https://github.com/mcxiaoke/packer-ng-plugin))

4. Obtain channel information

1. Friendly League and Android Studio acquisition methods

By reading tags in AndroidManifest

Private String getChannel () {try {PackageManager pm = getPackageManager (); ApplicationInfo appInfo = pm.getApplicationInfo (getPackageName (), PackageManager.GET_META_DATA); String channel = appInfo.metaData.getString (key); / / key is name if (! TextUtils.isEmpty (channel)) {return channel;}} catch (Exception e) {e.printStackTrace ();} return null;}

2. How to obtain Meituan's Walle

Meituan integrated with its own 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 is name if (! TextUtils.isEmpty (channel)) {return channel;}} catch (Exception e) {e.printStackTrace ();} return null;}
