how to add different flavours of same application(want to clone the application) with differnt google-services.json file in android project?

I want to clone my android app and launch it with a different name and a fresh new database in a different region, I don't want to write the code all over again or make a duplicate copy of the project. i used productFlavour{} in my build.gradle file in project, but i couldnt get it right.
flavour1 {
dimension 'default'
applicationId "com.example.flavour1"
}
flavour2 {
dimension 'default'
applicationId "com.example.flavour2"
}
I am getting this error that says
No signature of method: build_7epdrck7cjxe08sh65acsfob0.android() is applicable for argument types: (build_7epdrck7cjxe08sh65acsfob0$_run_closure1) values: [build_7epdrck7cjxe08sh65acsfob0$_run_closure1#29754fbc]
I also created two folders under my project src/ root folder with the same names of flavour1 and flavour2 and added their respective google-service.json file. but it's not working.
am I doing anything wrong?
this is my whole gradle file code except dependencies
apply plugin: 'com.android.application'
android {
compileSdkVersion 29
defaultConfig {
applicationId "com.example.scs"
minSdkVersion 21
targetSdkVersion 29
versionCode 1
versionName "1.0"
multiDexEnabled true
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled true
debuggable false
jniDebuggable false
renderscriptDebuggable false
pseudoLocalesEnabled false
zipAlignEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile(
'proguard-android-optimize.txt'),
'proguard-rules.pro'
}
}
productFlavours{
flavour1 {
dimension 'default'
applicationId "com.example.flavour1"
}
flavour2 {
dimension 'default'
applicationId "com.example.flavour2"
}
}
lintOptions {
checkReleaseBuilds false
abortOnError false
}
compileOptions {
targetCompatibility JavaVersion.VERSION_1_8
sourceCompatibility JavaVersion.VERSION_1_8
}
aaptOptions {
cruncherEnabled = true
}
}
any help or suggestion is greatly appreciated.
thanks in advance.

Flavors error - No matching client found for package name

i try to implement flavors by this guide:
https://proandroiddev.com/advanced-android-flavors-part-1-building-white-label-apps-on-android-ade16af23bcf
but i get this error:
No matching client found for package name 'com.example.client1'
this is my gradle:
android {
compileSdkVersion 28
defaultConfig {
applicationId 'com.example'
minSdkVersion 23
targetSdkVersion 28
versionCode 19
versionName '9.7'
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
flavorDimensions "default"
productFlavors {
ashkelon {
applicationIdSuffix ".client1"
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
and this is the source tree:
src/
main/
client1/
any help will be very appreciated!

It means you have only one google-services.json
you need to add one more google-services.json file for client1

How to install two separate versions of an app from android studio?

I am working with the Firebase chat project from github.
I am trying to make 2 apps, one client-side and one admin-side.
I have two copies of the project with different project names and different app names.
Still, I can't run both on the same device with android studio. Running one requires uninstalling the other.
I understand it might be a pretty basic thing, but any suggestions?
Thanks

what you need to do is change package name on App Build.Gradle, find applicationId and change one of your project package name
hopefully it works

In your app level build.gradle file under android tag define different product flavors for different app.
Please find the below code and do changes according to your project.
android {
compileSdkVersion 26
buildToolsVersion "26.0.2"
flavorDimensions "default"
project.archivesBaseName = "Visualogyx";
signingConfigs {
release {
storeFile file(System.getenv('KEYSTOREPATH'))
storePassword System.getenv("VISUALOGYX_KEYSTORE_PASSWORD")
keyAlias System.getenv("VISUALOGYX_KEYALIAS_NAME")
keyPassword System.getenv("VISUALOGYX_KEYALIAS_PASSWORD")
}
}
defaultConfig {
applicationId "com.visualogyx.app"
minSdkVersion 16
targetSdkVersion 26
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled true
signingConfig signingConfigs.release
ndk {
abiFilters "armeabi-v7a"
}
}
lintOptions {
// Or, if you prefer, you can continue to check for errors in release builds,
// but continue the build even when errors are found:
abortOnError false
}
dexOptions {
javaMaxHeapSize "4g"
jumboMode true
}
productFlavors {
dev {
versionCode 778899
versionName "v.1.1.BUILD_NUM"
applicationIdSuffix ".dev"
resValue "string", "app_name", "VisualogyxDEV"
buildConfigField "String", "HOST", System.getenv("VISUALOGYX_HOST_DEV")
}
qa {
versionCode 778899
versionName "v.1.0.BUILD_NUM"
applicationIdSuffix ".qa"
resValue "string", "app_name", "VisualogyxQA"
buildConfigField "String", "HOST", System.getenv("VISUALOGYX_HOST_QA")
}
pro {
versionCode 778899
versionName "v.1.0.BUILD_NUM"
resValue "string", "app_name", "Visualogyx"
buildConfigField "String", "HOST", System.getenv("VISUALOGYX_HOST_PRO")
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
applicationVariants.all { variant ->
variant.outputs.all {
outputFileName = "Visualogyx-${variant.baseName}-${variant.versionName}.apk"
}
}
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
packagingOptions {
exclude 'META-INF/XXX'
}
}
Hope it works.Thanks.

How to set different version number in android build types?

I need to set two different android build types i.e. staging and release.
defaultConfig {
applicationId "com.app.testing"
minSdkVersion 19
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
buildConfigField "String", "SERVER_URL", '"http://testing.com"'
}
dev {
applicationIdSuffix ".dev"
buildConfigField "String", "SERVER_URL", '"http://testing.com"'
}
Now I want to add versionName for each build type. How can I do that?
Edit
productFlavors{
release {
versionname = "1.0"
}
dev{
versionname = "1.0"
}
}

You can also use different version names for each build type without using flavors
In your app-module build.gradle:
defaultConfig {
...
versionName ""
}
...
buildTypes {
debug {
...
versionNameSuffix 'debug-version-1'
...
}
release {
...
versionNameSuffix 'version 1'
...
}
}
versionName "" did the trick.

You can use productFlavors like below:
productFlavors
{
test
{
applicationId 'com.example.test'
versionName '1.0.0.test'
versionCode 1
}
product
{
applicationId 'com.example.product'
versionName '1.0.0.product'
versionCode 1
}
}
You can define it under your default config. You can change from build variants. You can combine your build types with flavors.
Good luck.

The version code could be in minor versions to such as the following:
defaultConfig {
applicationId "com.app.testing"
minSdkVersion 19
targetSdkVersion 23
versionCode 3.2.1
versionName "1.0"
}
In the example above 3 denotes a major release which drastically updates the way an app would look like or its functionality. 2 denotes a bug fix/improvement which updates the app in some way or another, while 1 denotes a minor update or fix.
Hope this helps.

Defining buildTypes
As in your question above, you have correctly defined your two buildTypes, "release" and "dev".
Now I want to add versionName for each build type. How can I do that?
Iterating through buildTypes
A clean and more programmatic way to define your versionName (or any other defaultConfig parameter for that matter) for different buildTypes, is to iterate through all application variants and perform a specific action for your buildTypes using if statements:
android {
...
defaultConfig {
...
applicationVariants.all { variant ->
if(variant.buildType.name == "release") {
//Release
versionName "1.2.3"
} else if(variant.buildType.name == "dev") {
//Dev
versionName "3.2.1"
}
}
}
}

Android gradle product flavors with wearable apps

I'm adding a wearable component to an existing app which uses product flavors in the gradle build to build multiple versions of the app.
I know the package names / application Id's need to match between the mobile and wearable builds, but do I just need to copy the
productFlavors
signingConfigs
buildTypes
from my main mobile app. I'm not quite sure if all of this is needed to get things working or not.

The productFlavors no, unless you are going to do something specific for the wear app with a particular flavor.
The signingConfigs and buildTypes you should copy, the wear app definitely needs to be signed as well. You may adapt the buildType for wear such is enable/disable minify it you want from the main app.
Here's a portion of my own mobile and wear build configs
Mobile
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "org.codechimp.qrwear"
minSdkVersion 18
targetSdkVersion 20
versionCode 26
versionName "1.20"
}
productFlavors {
prod {
}
dev {
versionName = android.defaultConfig.versionName + " dev"
}
}
signingConfigs { release }
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
signingConfig signingConfigs.release
}
}
}
Wear
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "org.codechimp.qrwear"
minSdkVersion 20
targetSdkVersion 20
versionCode 26
versionName "1.20"
}
signingConfigs { release }
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
signingConfig signingConfigs.release
}
}
}
