i added buildscript and productFlavors in gradle module, but it generates error as shown below.

here I use kotlin and android studio dolphin
I expect no errors when syncing the project

How to override BuildConfig from Android-Library?

I have a Android Library and I am using it in app module. In library I use a BuildConfig.SPECIAL_VALUE.
I would like to override this BuildConfig in my app module build gradle.
I found similary question but It doesn't help me (Access buildConfigField from gradle in Android app)
I try this but is not working:
My app module build.gradle:
android {
publishNonDefault true
compileSdkVersion 28
flavorDimensions "default"
buildToolsVersion '28.0.3'
defaultConfig {
applicationId "app....id"
flavorDimensions "default"
minSdkVersion 23
targetSdkVersion 28
versionCode 1
versionName "1.0.0"
multiDexEnabled true
renderscriptTargetApi 18
renderscriptSupportModeEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
buildConfigField 'boolean', 'DEBUG_LOG_ENABLED', 'false'
signingConfig signingConfigs.productivity_mentor_release_config
debuggable = false
manifestPlaceholders = [crashlyticsEnabled: true]
}
debug {
testCoverageEnabled = false
buildConfigField 'boolean', 'DEBUG_LOG_ENABLED', 'true'
debuggable = true
manifestPlaceholders = [crashlyticsEnabled: false]
}
unitTest {
testCoverageEnabled = false
buildConfigField 'boolean', 'DEBUG_LOG_ENABLED', 'false'
manifestPlaceholders = [crashlyticsEnabled: false]
}
}
productFlavors {
develop {
buildConfigField 'boolean', 'LOG_EVENTS_TO_REMOTE_ENABLED', 'false'
buildConfigField 'boolean', 'FIREBASE_CRASH_ENABLED', 'false'
buildConfigField 'String', 'SPECIAL_VALUE', '"11"'
}
production {
buildConfigField 'boolean', 'LOG_EVENTS_TO_REMOTE_ENABLED', 'true'
buildConfigField 'boolean', 'FIREBASE_CRASH_ENABLED', 'true'
buildConfigField 'String', 'SPECIAL_VALUE', '"22"'
}
beta {
buildConfigField 'boolean', 'LOG_EVENTS_TO_REMOTE_ENABLED', 'true'
buildConfigField 'boolean', 'FIREBASE_CRASH_ENABLED', 'true'
buildConfigField 'String', 'SPECIAL_VALUE', '"33"'
}
roboTest {
minSdkVersion 18
buildConfigField 'boolean', 'LOG_EVENTS_TO_REMOTE_ENABLED', 'false'
buildConfigField 'boolean', 'FIREBASE_CRASH_ENABLED', 'true'
buildConfigField 'String', 'SPECIAL_VALUE', '"44"'
}
}
testOptions {
unitTests.returnDefaultValues = true
}
lintOptions {
abortOnError false
}
compileOptions {
sourceCompatibility = 1.8
targetCompatibility = 1.8
}
And my library build.gradle:
android {
compileSdkVersion 28
flavorDimensions "default"
buildToolsVersion '28.0.3'
publishNonDefault true
defaultConfig {
minSdkVersion 22
targetSdkVersion 28
multiDexEnabled true
renderscriptTargetApi 18
renderscriptSupportModeEnabled true
javaCompileOptions {
annotationProcessorOptions {
arguments = ["room.schemaLocation":
"$projectDir/schemas".toString()]
}
}
}
buildTypes {
release {}
debug {}
unitTest { }
}
productFlavors {
develop {
buildConfigField 'boolean', 'LOG_EVENTS_TO_REMOTE_ENABLED', 'false'
buildConfigField 'boolean', 'FIREBASE_CRASH_ENABLED', 'false'
buildConfigField 'String', 'SPECIAL_VALUE', '"1"'
}
production {
buildConfigField 'boolean', 'LOG_EVENTS_TO_REMOTE_ENABLED', 'true'
buildConfigField 'boolean', 'FIREBASE_CRASH_ENABLED', 'true'
buildConfigField 'String', 'SPECIAL_VALUE', '"2"'
}
beta {
buildConfigField 'boolean', 'LOG_EVENTS_TO_REMOTE_ENABLED', 'true'
buildConfigField 'boolean', 'FIREBASE_CRASH_ENABLED', 'true'
buildConfigField 'String', 'SPECIAL_VALUE', '"3"'
}
roboTest {
minSdkVersion 18
buildConfigField 'boolean', 'LOG_EVENTS_TO_REMOTE_ENABLED', 'false'
buildConfigField 'boolean', 'FIREBASE_CRASH_ENABLED', 'true'
buildConfigField 'String', 'SPECIAL_VALUE', '"4"'
}
}
testOptions {
unitTests.returnDefaultValues = true
}
lintOptions {
abortOnError false
}
compileOptions {
sourceCompatibility = 1.8
targetCompatibility = 1.8
}
}
ext {
google_services_version = '16.0.7'
}

Android app name depends on buildType and flavours Gradle

Below is an extract from my gradle source code. What I want to achieve is to add suffix to app name when buildType.debug is executed. I tried the following code, but variables are in gradle assigned in sequence as they are written in file and not as task order. So in the example below buildVariant variable will always be equal to Release.
{
def buildVariant = ""
buildTypes {
debug {
manifestPlaceholders = [showDebug: 'true']
buildVariant = " (DEBUG)"
}
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
manifestPlaceholders = [showDebug: 'false']
signingConfig signingConfigs.myConf
buildVariant = " Release"
}
}
productFlavors {
flavour1{
resValue 'string', 'app_name', 'Flavour1'+buildVariant
}
flavour2{
resValue 'string', 'app_name', 'Flavour2'+buildVariant
}
flavour3{
resValue 'string', 'app_name', 'Flavour3'+buildVariant
}
}

It was a really interesting puzzle to solve, so thanks for the question!
Here what you can do:
android {
compileSdkVersion 23
buildToolsVersion "23.0.0"
defaultConfig {
....
}
buildTypes {
debug {
}
release {
}
}
productFlavors {
FlavorA {
}
FlavorB {
}
}
applicationVariants.all { variant ->
variant.resValue "string", "app_name", '"' + variant.productFlavors.get(0).name + '_' + variant.buildType.name + '"'
}
}
dependencies {
}
As a result, it'd print the app name "FlavorA_debug", "FlavorB_release", etc.
(NB! I ran it with gradle classpath 'com.android.tools.build:gradle:1.3.0' - works great, though I didn't try with older versions)
