Default value for Gradle buildConfigField boolean used across flavors

Question

I have a number of flavors in my app, and I want to set a boolean buildConfigField for a subset of them. Is there a way to avoid having to add the field to every flavor? Ideally my build.gradle would look like the following:

productFlavors {
    flavor1 {
    }

    ....

    flavor4 {
        buildConfigField "boolean", "DISABLE_SOMETHING", "true"
    }

    flavor5 {
        buildConfigField "boolean", "DISABLE_SOMETHING", "true"
    }

    ....

    flavor8 {
    }
}

So in my app I can just go

if (BuildConfig.DISABLE_SOMETHING) {
    //disable stuff
}

However, compilation fails when I try to build with, for example, flavor1, as it can't find the field. I don't want to have to remember to add this to every new flavor I create. Are there any ways around this?

@Selvin nice spot, I didn't see that when I was searching. Thanks — Michael, Jun 25 '15 at 11:10

You can use defaultConfig for this (inside android{})

defaultConfig {
  buildConfigField "boolean", "DISABLE_SOMETHING", "true"
}

Also we can use `buildConfigField 'boolean', 'isEnableFeature', "false"` – Shailendra Madda Nov 17 '21 at 11:47
When I try this, I get that string "true" can't be cast to a boolean – Elliptica Sep 27 '22 at 12:52
