How to access variant.outputFileName in Kotlin

Question

We\'ve been using a snippet like this one to rename the APK file generated by our Gradle build:

android.applicationVariants.all { variant ->
    variant.o         


        

Answer 1

Shorter version using lambdas:

    applicationVariants.all{
        outputs.all {
            if(name.contains("release"))
                (this as BaseVariantOutputImpl).outputFileName = "../../apk/$name-$versionName.apk"
        }
    }

This will place APK into app/apk folder with name made of variant name and version code.
You can change the format of filename as you wish.
Important: it must be done only on release builds, because ".." in path corrupts debug build process with strange errors.
