Is it possible to declare a variable in gradle productFlavors and use it in Java?

Question

I know that in buildTypes I can declare, but I want to declare in productFlavors.

like this:

productFlavors {
    f1 {
        some_variable: "v_f1"
    }
    f2 {
        some_variable: "v_f2"
    }
}

Answer 1

Yes, like this:

productFlavors {
    f1 {
        buildConfigField "boolean", "aBoolean", "true"    
        buildConfigField "String", "aString", "foo"
    }
    f2 {
        buildConfigField "boolean", "aBoolean", "false"    
        buildConfigField "String", "aString", "bar"
    }
}

then at runtime you can access them like:

if (BuildConfig.aBoolean) {
    // do something
}
