Android Gradle - Add packageNameSuffix on specific productFlavor

Question

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.

Answer 1

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"
    }
}
