Why instead of string method returns Kotlin.Unit?

I have a regular method which through the presenter returns String from shared preferences class. The return value is correct and shows needed value string but in activity I received Kotlin.Unit instead of that value.

Where might be the issue is?

Shared pref class is java / Activity and presenter Kotlin

enter image description here

Code which in result returns string

public String getAdTimeLeft() {
    String result = "";
    String triggerTime = getTriggertTime();
    String currentTime = AdLauncher.getInstance().getCurrentTimeAsString();
    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy");
    Date triggerTimeDate = null;
    try {
        triggerTimeDate = simpleDateFormat.parse(triggerTime);
        Date currentTimeDate = simpleDateFormat.parse(currentTime);
        long difference = triggerTimeDate.getTime() - currentTimeDate.getTime();
        long days = (int) (difference / (1000*60*60*24));
        long hours = (int) ((difference - (1000*60*60*24*days)) / (1000*60*60));
        int min = (int) (difference - (1000*60*60*24*days) - (1000*60*60*hours)) / (1000*60);
        result = String.valueOf(min);
    } catch (ParseException e) {
        e.printStackTrace();
    }

    return result;
}

Suddenly figured out if I make a call directly from Pref class it works correct. Like this mTimeLeft.text = SharPrefManager.getInstance().adTimeLeft

But through presenter not working. This is presenter code SharPrefManager.getInstance().getAdTimeLeft()

Why with presenter it not working?

The solution was missed return state. By default Kotlin leave it as UNIT thats why as result I received kotlin.Unit text. The solution change looks like this

I changed presenter

fun grabAdTimeLeft(): String? {
    return SharPrefManager.getInstance().grabAdTimeLeft()
}
