If you want to append the version name and version code do it like:

applicationVariants.all { variant ->
        variant.outputs.all {
            def versionName = variant.versionName
            def versionCode = variant.versionCode
            def variantName = variant.name
            outputFileName = "${rootProject.name}" + '_' + variantName + '_' + versionName + '_' + versionCode + '.apk'
        }
    }
