Android Gradle. How to combine Flavors with buildTypes

Question

I'm working on a white brand app.

We create a different flavor per client and each client has Debug and Production APIs, so I'm trying to set them up in the Gradle.

How should I do that?

Here is what I've tried:

buildTypes {
    debug {
        // some configurations
    }
    release {
        // some configurations
    }
}

flavorDimensions "client"
productFlavors {
    company1{
        dimension "client"
        buildConfigField("String", "BASE_URL", "\"https://app.company1/devApi/\"")
    }

    company2 {
        dimension "client"
        buildConfigField("String", "BASE_URL", "\"https://app.company2/devApi/\"")
    }
}

EDIT: I would like to be able to define a different BASE_URL per each Flavor and Buildtype.

Flavor company1, BuildType debug

https://app.company1.com/devApi/

Flavor company1, BuildType release

https://app.company1.com/prodApi/

Flavor company2, BuildType debug

https://dev.company2.com/api/

Flavor company2, BuildType release

https://prod.company2.com/api/

Answer 1

For my specific problem, where the URLs differ a lot one to another, I couldn't make it work with Flavours and BuildTypes.

I was able to define the debug/production URLs by using specific strings.xml for each build variant (which is each combination of flavour and build type):

These are the folder structures to do so:

src/flavour1Debug/res/values/strings.xml 
src/flavour1Release/res/values/strings.xml 

and

src/flavour2Debug/res/values/strings.xml 
src/flavour2Release/res/values/strings.xml 

EXTRA: This can also be used to host different google-services.json files

Try something like this:

buildTypes {
    debug {
        buildConfigField("String", "BASE_URL_PATH", "\"devApi/\"")
    }
    release {
        buildConfigField("String", "BASE_URL_PATH", "\"prodApi/\"")
    }
}

flavorDimensions "client"
productFlavors {
    company1{
        dimension "client"
        buildConfigField("String", "BASE_URL_DOMAIN", "\"https://app.company1/\"")
    }

    company2 {
        dimension "client"
        buildConfigField("String", "BASE_URL_DOMAIN", "\"https://app.company2/\"")
    }
}

And use it like:

String BASE_URL = BuildConfig.BASE_URL_DOMAIN + BuildConfig.BASE_URL_PATH

Here is the working example

// Specifies one flavor dimension.

flavorDimensions "version"

productFlavors {
dev {
    dimension "version"
    applicationId "com.example.lk"
    versionCode 1
    versionName "1.0.1"
    buildConfigField("String", "BASE_URL_PATH", "\"https://app.dev.com/api/v1/\"")
}

prod {
    dimension "version"
    applicationId "com.example.in"
    versionCode 1
    versionName "1.0.1"
    buildConfigField("String", "BASE_URL_PATH", "\"https://app.prod.com/api/v1/\"")

}
staging {
    dimension "version"
    applicationId "com.example.other"
    versionCode 1
    versionName "1.0.1"
    buildConfigField("String", "BASE_URL_PATH", "\"https://app.staging.com/api/v1/\"")

}}




buildTypes {
    release {
      minifyEnabled true
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    debug {
      minifyEnabled false
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }

you can access it like this

String baseURL =BuildConfig.BASE_URL_PATH;
