Product Flavors

Demo app for add multiple Product Flavors

Product flavor is a variant of your app. It is very useful when you want to create multiple versions of your app.

Setting Up Product Flavors

Open up your build.gradle file in the app module and add your flavors inside the android section. The below example has 3 product flavors added with each having its own applicationId, signingConfig

 flavorDimensions 'flavors'
    productFlavors {
        flavor1 {
            dimension 'flavors'
            applicationId 'com.example.productflavours1'
            versionCode 1
            versionName '1.0.0'
            signingConfig signingConfigs.signKey1Config//specify sign key here
            resValue "string", "resvalue1", "valueFromGradle1"//create resource value from here.
            buildConfigField 'int', FIELD_NAME_BUILD_CONFIG_FIELD, "1"//create build config field
        }

        flavor2 {
            dimension 'flavors'
            applicationId 'com.example.productflavours2'
            versionCode 1
            versionName '1.0.0'
            signingConfig signingConfigs.signKey2Config//specify sign key here
        }

        flavor3 {
            dimension 'flavors'
            applicationId 'com.example.productflavours3'
            versionCode 1
            versionName '1.0.0'
            signingConfig signingConfigs.debug//specify sign key here.
        }
    }

configure signingConfig

 signingConfigs {
        //define multiple sign keys here
        signKey1Config {
            storeFile file('your_key_1.jks')
            keyAlias 'your_key_1'
            keyPassword 'your_key_1_pswd'
            storePassword 'your_key_1_pswd'
        }

        signKey2Config {
            storeFile file('your_key_2.jks')
            keyAlias 'your_key_2'
            keyPassword 'your_key_2_pswd'
            storePassword 'your_key_2_pswd'
        }
    }

Your main folder is the one that contains all the common and shared code between flavors, you can create flavor specific code and files by creating different source set for each flavor MyProject/app/src/main

Add multiple google-services json files based on the flavour

Get the flavor at runtime

You can check direct with flavor and your config name in everwhere, BuildConfig has already BuildType

if(BuildConfig.FLAVOR == "release"){// TODO}
else if(BuildConfig.FLAVOR == "staging"){ //TODO }
else if(BuildConfig.FLAVOR == "debug"){ //TODO }
