Fabric Beta and APK splits

I'm splitting my app based on ABI, not on density, like so:
splits {
abi {
enable true
reset()
include 'x86', 'armeabi', 'armeabi-v7a', 'mips', 'arm64-v8a'
universalApk true
}
}
I have multiple flavors, and 2 build types (debug and release). I want to put the universal apk file, that has native libs for all platforms, up on fabric beta. From what I understand, this is supported through the ext.betaDistributionApkFilePath attribute.
I can define this either at the buildType level, or at the flavor level. The problem is I need both build type and flavor to pick up my variant - something like this:
android.applicationVariants.all { variant ->
variant.ext.betaDistributionApkFilePath = "${buildDir}/outputs/apk/app-${variant.productFlavors[0].name}-universal-${variant.buildType.name}.apk"
}
or
gradle.taskGraph.beforeTask { Task task ->
if(task.name ==~ /crashlyticsUploadDistribution.*/) {
System.out.println("task name: ${task.name}");
android.applicationVariants.all { variant ->
System.out.println("match: crashlyticsUploadDistribution${variant.name}");
if(task.name ==~ /(?i)crashlyticsUploadDistribution${variant.name}/){
ext.betaDistributionApkFilePath = "${buildDir}/outputs/apk/app-${variant.productFlavors[0].name}-universal-${variant.buildType.name}.apk"
System.out.println(ext.betaDistributionApkFilePath);
}
}
}
Unfortunately this doesn't seem to work - is there any way to do this currently?

For every existing variant you can add an action that will execute before Crashlytics tasks and set ext.betaDistributionApkFilePath according to the variant name. That's how it looks like:
android.applicationVariants.all { variant ->
variant.outputs.each { output ->
// Filter is null for universal APKs.
def filter = output.getFilter(com.android.build.OutputFile.ABI)
if (filter == null) {
tasks.findAll {
it.name.startsWith(
"crashlyticsUploadDistribution${variant.name.capitalize()}")
}.each {
it.doFirst {
ext.betaDistributionApkFilePath = output.outputFile.absolutePath
}
}
tasks.findAll {
it.name.startsWith(
"crashlyticsUploadSymbols${variant.name.capitalize()}")
}.each {
it.doFirst {
ext.betaDistributionApkFilePath = output.outputFile.absolutePath
}
}
}
}
}

How to change the proguard mapping file name in gradle for Android project

I have android project based on gradle and I want to change mapping.txt file name after it's generated for my build. How can it be done?
upd
How it can be done in build.gradle? Since I have access there to my flavors and other stiff, I would like to create mapping file name based on flavor/build variant version.

Simpler solution.
applicationVariants.all { variant ->
if (variant.getBuildType().isMinifyEnabled()) {
variant.assemble.doLast {
copy {
from variant.mappingFile
into "${rootDir}/proguardTools"
rename { String fileName ->
"mapping-${variant.name}.txt"
}
}
}
}
}

As of today (May 2020) former solution, which uses variant.mappingFile is not working anymore in new Android Gradle plugin (Android Studio) 3.6 and higher.
Instead variant.mappingFile returns null and following is displayed in the logs:
WARNING: API 'variant.getMappingFile()' is obsolete and has been replaced with 'variant.getMappingFileProvider()'.
I am sharing my working solution, which uses new api:
applicationVariants.all { variant ->
variant.assembleProvider.get().doLast {
def mappingFiles = variant.getMappingFileProvider().get().files
for (file in mappingFiles) {
if (file != null && file.exists()) {
def nameMatchingApkFile = "$archivesBaseName-$variant.baseName-$file.name"
def newMappingFile = new File(file.parent, nameMatchingApkFile)
newMappingFile.delete() //clean-up if exists already
file.renameTo(newMappingFile)
}
}
}
}
Note, that variant.getBuildType().isMinifyEnabled() is not used since we are using DexGuard.
The code above makes mapping file's name match apk's file name.
Just in case, if you need to change apk name - following could be used:
android {
defaultConfig {
//resulting apk will looks like: "archive base name" + -<flavour>-<buildType>.apk
archivesBaseName = "$applicationId-$versionName"
}
}

Use this command in your proguard-rules.pro file:
-printmapping path/to/your/file/file_name.txt
the file will be written in part {root}/path/to/your/file with file_name.txt name.
If you want to have different setting for different flavors you can define many proguard-rules for them
I found one more idea but I am not sure that it is right way.
You can define your path in flavors:
productFlavors {
test1 {
applicationId "com.android.application.test"
project.ext."${name}Path" = 'path/one/mapp.txt'
}
test2 {
project.ext."${name}Path" = 'path/two/mapp.txt'
}
}
And as next you can define new task before $asseble{variant.name.capitalize()} task as is shown below:
android.applicationVariants.all { variant ->
def envFlavor = variant.productFlavors.get(0).name
def modifyProguardPath = tasks.create(name: "modifyProguardFor${variant.name.capitalize()}", type: Exec) {
def pathToMap = project."${envFlavor}Test1"
doFirst {
println "==== Edit start: $pathToMap ===="
}
doLast {
println "==== Edit end: $pathToMap ===="
}
executable "${rootDir}/utils/test.bash"
args pathToMap
}
project.tasks["assemble${variant.name.capitalize()}"].dependsOn(modifyProguardPath);
}
and in script ${root}/utils/test.bash - you can modify proguard-rules.pro.
But I think that exist better solution.

Many thanx to Sergii Pechenizkyi who helped me to found this good solution.
To implement copying of proguard mapping files for each flavor we can create "root" task copyProguardMappingTask and number of dynamic tasks for each flavor
def copyProguardMappingTask = project.tasks.create("copyProguardMapping")
applicationVariants.all { variant ->
variant.outputs.each { output ->
...
if (variant.getBuildType().isMinifyEnabled()) {
def copyProguardMappingVariantTask = project.tasks.create("copyProguardMapping${variant.name.capitalize()}", Copy)
def fromPath = variant.mappingFile;
def intoPath = output.outputFile.parent;
copyProguardMappingVariantTask.from(fromPath)
copyProguardMappingVariantTask.into(intoPath)
copyProguardMappingVariantTask.rename('mapping.txt', "mapping-${variant.name}.txt")
copyProguardMappingVariantTask.mustRunAfter variant.assemble
copyProguardMappingTask.dependsOn copyProguardMappingVariantTask
}
}
}
afterwards we should run this task after assembling our project. I use jenkins and my tasks option looks like
gradle clean assembleProjectName copyProguardMapping
It works like a charm.

Since the last update variant.mappingFile is not longer available.
(I use ProGuard version 4.7, AndroidStudio 2.0)
This is (part of) my build.gradle file:
import java.util.regex.Matcher
import java.util.regex.Pattern
def getCurrentFlavor() {
Gradle gradle = getGradle()
String tskReqStr = gradle.getStartParameter().getTaskRequests().toString()
Pattern pattern;
if( tskReqStr.contains( "assemble" ) )
pattern = Pattern.compile("assemble(\\w+)(Release|Debug)")
else
pattern = Pattern.compile("generate(\\w+)(Release|Debug)")
Matcher matcher = pattern.matcher( tskReqStr )
if( matcher.find() )
return matcher.group(1).toLowerCase()
else
{
println "NO MATCH FOUND"
return "";
}
}
buildTypes {
release {
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
minifyEnabled true
applicationVariants.all { variant ->
variant.outputs.each { output ->
output.outputFile = new File(output.outputFile.parent, "${variant.name}_v${variant.versionName}.apk")
}
def mappingFile = "${rootDir}\\app\\build\\outputs\\mapping\\${getCurrentFlavor()}\\release\\mapping.txt"
println("mappingFile: ${mappingFile}")
if (variant.getBuildType().isMinifyEnabled()) {
variant.assemble.doLast {
copy {
from "${mappingFile}"
into "${rootDir}"
rename { String fileName ->
"mapping-${variant.name}.txt"
}
}
}
}
}
}
debug {
minifyEnabled false
useProguard false
applicationVariants.all { variant ->
variant.outputs.each { output ->
output.outputFile = new File(output.outputFile.parent, "${variant.name}_v${variant.versionName}.apk")
}
}
}
}

variant.assemble is now deprecated, suggested solution incorporating previous modifications:
archivesBaseName = "MyCompany-MyAppName-$versionName"
...
applicationVariants.all { variant ->
variant.assembleProvider.get().doLast {
if (variant.mappingFile != null && variant.mappingFile.exists()) {
def mappingFilename = "$archivesBaseName-$variant.baseName-mapping.txt"
(new File(variant.mappingFile.parent, mappingFilename)).delete()
variant.mappingFile.renameTo(variant.mappingFile.parent +
"/" + mappingFilename)
}
}
}
If using app bundle (aab) instead of apk, add this to after the android section:
afterEvaluate {
bundleRelease.doLast {
android.applicationVariants.all { variant ->
if (variant.buildType.name == 'release') {
tasks.create(name: "renameMappingFile") {
if (variant.mappingFile != null && variant.mappingFile.exists()) {
variant.mappingFile.renameTo(variant.mappingFile.parent + "/$variant.baseName-$versionName-${new Date().format('yyyy-MM-dd_HHmm')}-mapping.txt")
}
}
}
}
}
}
Swap bundleRelease for assembleRelease for apks in the last example too.
Update: However that last doesn't work if you try and build a normal debug directly to your phone then. Error:
Could not get unknown property 'bundleRelease' for project ':app' of type org.gradle.api.Project.

This is a variation of igorpst's answer but renames mapping.txt to match the apk's name exactly including the app version name. I've combined this with code to name the APK with a version number as described in this answer. I had to snoop through the gradle source code to find $variant.baseName
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.company.app"
minSdkVersion 13
targetSdkVersion 21
versionCode 14 // increment with every release
versionName '1.4.8' // change with every release
archivesBaseName = "MyCompany-MyAppName-$versionName"
}
applicationVariants.all { variant ->
if (variant.getBuildType().isMinifyEnabled()) {
variant.assemble.doLast {
(new File(variant.mappingFile.parent, "$archivesBaseName-$variant.baseName-mapping.txt")).delete();
variant.mappingFile.renameTo(variant.mappingFile.parent +
"/$archivesBaseName-$variant.baseName-mapping.txt")
}
}
}
}

All these answers used copy to rename the file.
I didn't want to move the file however, I just wanted to change it's name, keeping in mind the build type and flavor.
I based myself on the code from the other posters here and changed it up a bit.
Since Minify can be false, while still using proguard, I just check if the file is present.
Following code accomplishes just that.
android {
applicationVariants.all { variant ->
variant.assemble.doLast {
def mappingFolderUrl = "${project.buildDir.path}/outputs/mapping/"
if (variant.buildType.name) {
mappingFolderUrl += variant.buildType.name + "/"
}
if (variant.flavorName) {
mappingFolderUrl += variant.flavorName + "/"
}
def mappingFileUrl = mappingFolderUrl + "mapping.txt"
logger.lifecycle("mappingFile path: ${mappingFileUrl}")
File mappingFile = file(mappingFileUrl)
if (mappingFile.exists()) {
def newFileName = mappingFolderUrl + "mapping-${variant.name}.txt"
mappingFile.renameTo(newFileName)
}
}
}
}
NOTE
You could probably use this code to move the file as well.
the .renameTo() method expects a full path, If you change the path, I would suppose you effectively move the File to another place.

A complete solution that worked for me
applicationVariants.all { variant ->
def variantType = variant.buildType.name
if (variantType == "release") {
variant.assemble.doLast {
def mappingFile = variant.mappingFile
mappingFile.renameTo(mappingFile.parent + "/mapping-${variant.name}.txt")
}
}
}

For Android Studio Gradle Plugin Version 4.1.0 and newer (since about May 2020)
This version fixes the following warning:
WARNING: API 'variant.getMappingFile()' is obsolete and has been replaced with 'variant.getMappingFileProvider()'.
applicationVariants.all { variant ->
variant.assembleProvider.get().doLast {
def mappingFileProvider = variant.getMappingFileProvider().get()
if (mappingFileProvider != null) {
try {
def mappingFiles = mappingFileProvider.getFiles()
for (mappingFile in mappingFiles) {
if (mappingFile != null && mappingFile.exists()) {
def newMappingFileName = "$archivesBaseName-$variant.baseName-$mappingFile.name"
project.logger.lifecycle("Renaming '${mappingFile.name}' to '${newMappingFileName}'")
def newMappingFile = new File(mappingFile.parent, newMappingFileName)
newMappingFile.delete()
mappingFile.renameTo(newMappingFile)
}
}
} catch (Exception ignored) {
project.logger.lifecycle("No mapping files found to rename")
}
}
}
}
For Android Studio Gradle Plugin Version 3.3.0 (January 2019) through about May 2020
This overcomes previous issues where Android 3.0/Android Gradle Plugin 3.0 deprecated BuildType.isMinifyEnabled() and the gradle plugin deprecated variant.getAssemble().
applicationVariants.all { variant ->
variant.assembleProvider.get().doLast {
if (variant.mappingFile != null && variant.mappingFile.exists()) {
def mappingFilename = "$archivesBaseName-$variant.baseName-mapping.txt"
(new File(variant.mappingFile.parent, mappingFilename)).delete()
variant.mappingFile.renameTo(variant.mappingFile.parent +
"/" + mappingFilename)
}
}
}

Pinhassi's solution above works great and it is conforms to the latest Gradle changes. There are a couple of things though that I had to change:
The module name is hardcoded ("app"), which is not ideal since in a lot of cases (including mine) that will not be true. It is better to dynamically detect the module name.
The mapping file also only conforms to the Windows file system by having backward escaped slashes ("\"). If you are on a *NIX system like Linux or Mac, you need to replace those with forward non escaped slashes ("/")
Changed a bit the renaming of the .apk file to include the project name and added a date/time stamp at the end.
Here is the finished code:
import java.util.regex.Matcher
import java.util.regex.Pattern
buildTypes {
release {
debuggable false
minifyEnabled true
proguardFiles 'proguard.cfg'
// Rename the apk file and copy the ProGuard mapping file to the root of the project
applicationVariants.all { variant ->
if (variant.getBuildType().name.equals("release")) {
def formattedDate = new Date().format('yyyyMMddHHmmss')
def projectName = ""
variant.outputs.each { output ->
def fullName = output.outputFile.name
projectName = fullName.substring(0, fullName.indexOf('-'))
// ${variant.name} has the value of "paidRelease"
output.outputFile = new File((String) output.outputFile.parent, (String) output.outputFile.name.replace(".apk", "-v${variant.versionName}-${formattedDate}.apk"))
}
def mappingFile = "${rootDir}/${projectName}/build/outputs/mapping/${getCurrentFlavor()}/release/mapping.txt"
println("mappingFile: ${mappingFile}")
if (variant.getBuildType().isMinifyEnabled()) {
variant.assemble.doLast {
copy {
from "${mappingFile}"
into "${rootDir}"
rename { String fileName ->
"mapping-${variant.name}.txt"
}
}
}
}
}
}
}
debug {
debuggable true
}
}
def getCurrentFlavor() {
Gradle gradle = getGradle()
String tskReqStr = gradle.getStartParameter().getTaskRequests().toString()
Pattern pattern;
if( tskReqStr.contains( "assemble" ) )
pattern = Pattern.compile("assemble(\\w+)(Release|Debug)")
else
pattern = Pattern.compile("generate(\\w+)(Release|Debug)")
Matcher matcher = pattern.matcher( tskReqStr )
if( matcher.find() )
return matcher.group(1).toLowerCase()
else {
println "NO MATCH FOUND"
return "";
}
}

applicationVariants.all { variant ->
variant.outputs.each { output ->
if (variant.getBuildType().isMinifyEnabled()) {
variant.assemble.doLast{
copy {
from variant.mappingFile
into "${rootDir}/mapping"
rename { String fileName ->
"mapping-${variant.name}-${new Date().format('yyyy_MM_dd')}.txt"
}
}
}
}
}
}

Here is solution that helps me:
compileSdkVersion 30
JavaVersion.VERSION_1_8
kotlin_version = '1.5.31'
com.android.tools.build:gradle:7.0.2
buildTypes {
release {
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
applicationVariants.all { variant ->
// Generating apk file for each flavour release build
variant.outputs.all {
outputFileName = "${variant.flavorName}-${variant.versionCode}.apk"
}
// Generating mapping file for each flavour release build
if (variant.getBuildType().isMinifyEnabled()) {
variant.assembleProvider.get().doLast {
def files = variant.getMappingFileProvider().get().getFiles()
for (file in files) {
if (file != null && file.exists()) {
def newName = "mapping-${variant.flavorName}-${variant.versionCode}.txt"
def newFile = new File(file.parent, newName)
newFile.delete()
file.renameTo(newName)
}
}
}
}
}
}

Gradle: android.variantFilter cause build fail after upgrade to Gradle 2.2.1

I am working in an Android project which has many flavors, I used this code in build.gradle to set the package name for each flavor:
flavorDimensions "type", "feature"
productFlavors {
abc { flavorDimension "type" }
def { flavorDimension "type" }
ABC { flavorDimension "feature" }
DEF { flavorDimension "feature" }
}
android.variantFilter { variant ->
def flavorString = ""
def flavors = variant.getFlavors()
for (int i = 0; i < flavors.size(); i++) {
flavorString += flavors[i].name;
}
if(flavorString.equalsIgnoreCase("abcABC")) {
variant.getDefaultConfig().applicationId "com.my.app.abc.abc"
}
if(flavorString.equalsIgnoreCase("abcDEF")) {
variant.getDefaultConfig().applicationId "com.my.app.abc.def"
}
if(flavorString.equalsIgnoreCase("defABC")) {
variant.getDefaultConfig().applicationId "com.my.app.def.abc"
}
if(flavorString.equalsIgnoreCase("defDEF")) {
variant.getDefaultConfig().applicationId "com.my.app.def.def"
}
}
Everything was fine until I updated my gradle from 1.10.0 to 2.2.1, the build is failed and I get this error message:
Error:(63, 0) No signature of method: com.android.build.gradle.internal.api.ReadOnlyProductFlavor.applicationId() is applicable for argument types: (java.lang.String) values: [com.hac.apps.megahd.acc]
Possible solutions: getApplicationId()
It seems like the variant.getDefaultConfig().applicationId is working different now. I searched the internet for the document for android.variantFilter but it seems not to be exist.
Anyone can tell me how do I get this code work in gradle 2.2.1? Thanks a lot.

The variantFilter is meant to be used only to allow or disallow builds of certain combinations. The defaultConfig object is shared and read-only. If you want to assign applicationId's to variants, I think you should something more similar to this:
buildTypes {
applicationVariants.all { variant ->
def projectFlavorNames = []
variant.productFlavors.each() { flavor ->
projectFlavorNames.add(flavor.name)
}
project.logger.debug('Application variant ' + variant.name + '. Flavor names list: ' + projectFlavorNames)
if (projectFlavorNames.contains('customer1') && projectFlavorNames.contains('variant1')) {
variant.mergedFlavor.applicationId = 'com.customer1.variant1'
} else if (projectFlavorNames.contains('customer2') && projectFlavorNames.contains('variant2')) {
variant.mergedFlavor.applicationId = 'com.customer2.variant2'
} // else use standard package name
project.logger.debug('Using project name: ' + variant.packageName)
}
// ...
}
From Dynamically generate package name for multi-flavors configuration

Exclude specific build variants

I have the two default build types: debug / release and a couple of flavors: prod / dev.
Now I want to exclude the build variant dev-release, but keep all other possible combinations. Is there a way to achieve this?

Variant filter
Use the variantFilter of the gradle android plugin to mark certain combinations as ignored. Here is an example from the official documentation that works with flavor dimensions and shows how it can be used:
android {
...
buildTypes {...}
flavorDimensions "api", "mode"
productFlavors {
demo {...}
full {...}
minApi24 {...}
minApi23 {...}
minApi21 {...}
}
variantFilter { variant ->
def names = variant.flavors*.name
// To check for a certain build type, use variant.buildType.name == "<buildType>"
if (names.contains("minApi21") && names.contains("demo")) {
// Gradle ignores any variants that satisfy the conditions above.
setIgnore(true)
}
}
}
As the comment says, you can also check the buildType like so:
android {
variantFilter { variant ->
def names = variant.flavors*.name
if(variant.buildType.name == 'release' && names.contains("myforbiddenflavor")) {
setIgnore(true)
}
}
}

Using variant filters like others I found it was easiest to do this by comparing the variant name against a list of variants that I want to keep.
So in my app/build.gradle file I have something like:
android {
variantFilter { variant ->
def needed = variant.name in [
'stagingQuickDebug', // for development
'stagingFullDebug', // for debugging all configurations
'stagingFullCandidate', // for local builds before beta release
'stagingFullRelease', // for beta releases
'productionFullCandidate', // for local builds before going public
'productionFullRelease' // for public releases
]
variant.setIgnore(!needed)
}
buildTypes {
debug {
}
release {
}
candidate.initWith(release)
}
flavorDimensions "server", "build"
productFlavors {
staging {
dimension "server"
buildConfigField "String", "API_URL", '"https://example-preprod.com/"'
}
production {
dimension "server"
buildConfigField "String", "API_URL", '"https://example.com/"'
}
quick {
dimension "build"
minSdkVersion 21
resConfigs("en", "xxhdpi")
}
full {
dimension "build"
}
}
}

When working with flavor dimensions try this one
variantFilter { variant ->
def dim = variant.flavors.collectEntries {
[(it.productFlavor.dimension): it.productFlavor.name]
}
if (dim.dimensionOne == 'paid' && dim.dimensionSecond == 'someVal') {
variant.setIgnore(true);
}
}

If you use flavor dimensions do this:
flavorDimensions "device", "server"
productFlavors {
emulator {
dimension = "device"
}
phone {
dimension = "device"
}
staging {
dimension = "server"
}
production {
dimension = "server"
}
}
android.variantFilter { variant ->
def device = variant.getFlavors().get(0).name
def server = variant.getFlavors().get(1).name
def isRelease = variant.buildType.name.equals('release')
def isDebug = variant.buildType.name.equals('debug')
// Disable emulatorProductionRelease build variant
if (device.equals('emulator') && server.equals('production') && isRelease) {
variant.setIgnore(true)
}
}
It's easy to read and you can target specific build variants.

The solutions here didn't work for me - I run into this post and added this to build.gradle in my app and it solved the issue for me
gradle.taskGraph.whenReady { graph ->
graph.allTasks.findAll { it.name ==~ /.*MyVariant.*/ }*.enabled = false
}
This is what it does - waits for gradle to assemble the complete list of tasks to execute and then it marks all the tasks that match the name pattern as disabled
NOTE
The match is exact - the expression above lets you match any task that has "MyVariant" somewhere in it's name and it is case sensitive

One more simpler way
android.variantFilter { variant ->
if (variant.name == "qaDebug" || variant.name == "devRelease") {
setIgnore(true)
}
}
Or if you place this code inside android {} closure, android. can be omitted
android {
// Please always specify the reason for such filtering
variantFilter { variant ->
if (variant.name == "qaDebug" || variant.name == "devRelease") {
setIgnore(true)
}
}
}
Please always put a meaningful comment for things like this.
UPD: For Kotlin Gradle DSL there is another way:
android {
variantFilter {
ignore = listOf("qaDebug", "devRelease").contains(name)
}
}

The answer of #ade.se didn't work for me. But I've struggled a little, and written this, that works great:
android {
compileSdkVersion 22
buildToolsVersion '20.0.0'
variantFilter { variant ->
if (variant.buildType.name.equals('debug') || variant.buildType.name.equals('release')) {
variant.setIgnore(true);
}
}
defaultConfig {
applicationId "com.fewlaps.quitnow"
minSdkVersion 15
targetSdkVersion 22
versionCode 35
versionName "1.35"
}
The code you have to add is the variantFilter one, but I've pasted a little of the context to make it easy to understand.

See Variant filter answer above.
Old Answer:
It's not possible at the moment, but it's something we want to add. Probably soon.
In the meantime you could disable the assemble task I think. Something like this:
android.applicationVariants.all { variant ->
if ("devRelease".equals(variant.name)) {
variant.assembleTask.enabled = false
}
}

In Gradle's Kotlin DSL (i.e. build.gradle.kts), that would be:
variantFilter {
ignore = buildType.name == "release" &&
flavors.map { it.name }.contains("dev")
}

Android Gradle - Add packageNameSuffix on specific productFlavor

I have a Gradle Android Project with this product Groups and Flavors configuration:
/*
* Define different flavor groups
*/
flavorGroups 'market', 'version'
/*
* Defile product flavors
*/
productFlavors {
amazon {
flavorGroup 'market'
}
google {
flavorGroup 'market'
}
flav1 {
flavorGroup 'version'
packageName 'com.company.flav1'
}
flav2 {
flavorGroup 'version'
packageName 'com.company.flav2'
}
flav3 {
flavorGroup 'version'
packageName 'com.company.flav3'
}
}
// .. Other stuff
It works great. All sources and resources are merged correctly.
But for specific reasons I need the package suffix to be .amz for the amazon product flavor. How can I achieve that?
I tried this way:
amazon {
flavorGroup 'market'
packageNameSuffix '.amz'
}
but gradle throws an exception.

This is not possible at the moment.
packageNameSuffix is strictly a property of Build Type.
I'd like to offer a way to customize the ProductFlavor's values for a given variant (ie a given combination of all flavor dimensions and of build type) but it's not possible at the moment.
Instead of a new dimension of flavor, you could do a "amzRelease" buildtype that extends the existing release buildtype and add a suffix.
If your current "amazon" flavor does more (configure versionCode/Name/etc...), it won't work though. You could then use both your amazon flavor and a amzRelease build type. It'll create a lot more variants than you need but it'd work until we have some better.

You could use a variant of the solution I've written about here: https://stackoverflow.com/a/26585241/4177090
In short, you can find the combined variants using variantFilter and then update the appliciationId from there:
android.variantFilter { variant ->
def flavorString = ""
def flavors = variant.getFlavors()
for (int i = 0; i < flavors.size(); i++) {
flavorString += flavors[i].name;
}
if(flavorString.contains("amazon")) {
variant.getDefaultConfig().applicationId variant.getDefaultConfig().applicationId + ".amz"
}
}

Working solution for gradle 1.0.0+:
android.applicationVariants.all { variant ->
def flavorName = variant.getVariantData().getVariantConfiguration().getFlavorName()
def mergedFlavour = variant.getVariantData().getVariantConfiguration().getMergedFlavor();
if (flavorName.toLowerCase().contains("amazon")) {
mergedFlavour.setApplicationId(mergedFlavour.getApplicationId() + ".amz")
}
}
