Answer 1

How can you insert String result of function into buildConfigField

Here's an example of build date in human-readable format set:

def getDate() {
    return new SimpleDateFormat("dd MMMM yyyy", new Locale("ru")).format(new Date())
}

def buildDate = getDate()

defaultConfig {
    buildConfigField "String", "BUILD_DATE", "\"$buildDate\""
}
