Android Studio Tutorial (vi) : Gradle multi channel package

Due to the large number of channels in the domestic Android market, in order to count the downloads and other data statistics of each channel, we need to pack separately for each channel. It would be boring for you to pack packages for more than 10 markets, but with Gradle, this is no longer a problem.
Umeng multi-channel package
Without further ado, for example, in AndroidManifest.xml there is a paragraph like this:
<meta-data
android:name="UMENG_CHANNEL"
android:value="Channel_ID" />
Channel_ID inside is the channel designation. The goal is to have this value change automatically at compile time.
Step 1 Configure PlaceHolder in ES16en.ES17en
<meta-data
android:name="UMENG_CHANNEL"
android:value="${UMENG_CHANNEL_VALUE}" />
Step 2 Set productFlavors on ES22en.gradle
android {
productFlavors {
xiaomi {
manifestPlaceholders = [UMENG_CHANNEL_VALUE: "xiaomi"]
}
_360 {
manifestPlaceholders = [UMENG_CHANNEL_VALUE: "_360"]
}
baidu {
manifestPlaceholders = [UMENG_CHANNEL_VALUE: "baidu"]
}
wandoujia {
manifestPlaceholders = [UMENG_CHANNEL_VALUE: "wandoujia"]
}
}
}
Or batch modification
android {
productFlavors {
xiaomi {}
_360 {}
baidu {}
wandoujia {}
}
productFlavors.all {
flavor -> flavor.manifestPlaceholders = [UMENG_CHANNEL_VALUE: name]
}
}
It's simple, it's clear, right? Direct execution./gradlew assembleRelease, then you can quietly drink a cup of coffee and wait for the packaging to complete.
assemble combines Build Variants to create task
In my last blog, I introduced the command assemble. I will combine Build Type to create my own task, such as:
./gradlew assembleDebug
./gradlew assembleRelease
In addition, assemble can also combine with Product Flavor to create new tasks. In fact, assemble is used in combination with Build Variants 1, and Build Variants = Build Type + Product Flavor.
If we want to package the release version of the wandoujia channel, just execute the following command:
./gradlew assembleWandoujiaRelease
If we only type wandoujia channel version, then:
./gradlew assembleWandoujia
This command generates versions of Release and Debug for the wandoujia channel
Similarly, I would like to type all versions of Release:
./gradlew assembleRelease
This command will type out the Release version for all channels under Product Flavor.
In summary, the assemble command creates task as follows:
**assemble** : Allows you to directly build 1 VERSION of Variant, such as assembleFlavor1Debug.
**assemble** : Allows you to build all APK that specify Build Type. For example, assembleDebug will build Flavor1Debug and Flavor2Debug.
**assemble** : Allows you to build all APK that specify flavor. For example, assembleFlavor1 will build Flavor1Debug and Flavor1Release.
The complete gradle script
Finally, a copy of the complete gradle file configuration that I used in the project:
apply plugin: 'com.android.application'
def releaseTime() {
return new Date().format("yyyy-MM-dd", TimeZone.getTimeZone("UTC"))
}
android {
compileSdkVersion 21
buildToolsVersion '21.1.2'
defaultConfig {
applicationId "com.boohee.*"
minSdkVersion 14
targetSdkVersion 21
versionCode 1
versionName "1.0"
// dex breakthrough 65535 The limits of
multiDexEnabled true
// The default is umeng The channel
manifestPlaceholders = [UMENG_CHANNEL_VALUE: "umeng"]
}
lintOptions {
abortOnError false
}
signingConfigs {
debug {
// No debug config
}
release {
storeFile file("../yourapp.keystore")
storePassword "your password"
keyAlias "your alias"
keyPassword "your password"
}
}
buildTypes {
debug {
// According to Log
buildConfigField "boolean", "LOG_DEBUG", "true"
versionNameSuffix "-debug"
minifyEnabled false
zipAlignEnabled false
shrinkResources false
signingConfig signingConfigs.debug
}
release {
// Don't show Log
buildConfigField "boolean", "LOG_DEBUG", "false"
minifyEnabled true
zipAlignEnabled true
// Remove useless resource file
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
signingConfig signingConfigs.release
applicationVariants.all { variant ->
variant.outputs.each { output ->
def outputFile = output.outputFile
if (outputFile != null && outputFile.name.endsWith('.apk')) {
// The output apk The name for boohee_v1.0_2015-01-15_wandoujia.apk
def fileName = "boohee_v${defaultConfig.versionName}_${releaseTime()}_${variant.productFlavors[0].name}.apk"
output.outputFile = new File(outputFile.parent, fileName)
}
}
}
}
}
// Umeng multi-channel package
productFlavors {
wandoujia {}
_360 {}
baidu {}
xiaomi {}
tencent {}
taobao {}
...
}
productFlavors.all { flavor ->
flavor.manifestPlaceholders = [UMENG_CHANNEL_VALUE: name]
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:support-v4:21.0.3'
compile 'com.jakewharton:butterknife:6.0.0'
...
}
