Titanium auto updated time remaining label

Question

I am trying to create a label in a Titanium developed Android app that automatically updates the time remaining based on my inputs (from current date to 30 May 2014). I've used JavaScript to create the following countdown function:

var current = 'Today is the day!';
var montharray = new Array('Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec');
function countdown(yr,m,d){
    theyear = yr;
    themonth = m;
    theday = d;
    var today = new Date();
    var todayy = today.getYear();
    var todaym = today.getMonth();
    var todayd = today.getDate();
    var todayh = today.getHours();
    var todaymin = today.getMinutes();
    var todaysec = today.getSeconds();
    var todaystring = montharray[todaym]+" "+todayd+", "+todayy+" "+todayh+":"+todaymin+":"+todaysec;
    futurestring = montharray[m-1]+" "+d+", "+yr;
    dd = Date.parse(futurestring) - Date.parse(todaystring);
    dday = Math.floor(dd/(60*60*1000*24)*1);
    dhour = Math.floor((dd%(60*60*1000*24))/(60*60*1000)*1);
    dmin = Math.floor(((dd%(60*60*1000*24))%(60*60*1000))/(60*1000)*1);
    dsec = Math.floor((((dd%(60*60*1000*24))%(60*60*1000))%(60*1000))/1000*1);
    if (dday==0 && dhour==0 && dmin==0 && dsec==1){
        homeLabel6.text = current;
        return;
    } else {
        homeLabel6.text = dday + 'd:'+ dhour + 'h:' + dmin + 'm:' + dsec + 's';
        setTimeout('countdown(theyear,themonth,theday)',1000);
    }
}
countdown(2014,05,30);

Unfortunately when I build the app on my phone I receive the following errors:

[ERROR] :  TiApplication: (KrollRuntimeThread) [821,821] Sending event: exception on thread: KrollRuntimeThread msg:java.lang.IncompatibleClassChangeError: interface not implemented; Titanium 3.2.2,2014/03/05 12:22,96e9a07

[ERROR] :  TiApplication:   at org.appcelerator.kroll.KrollRuntime$KrollRuntimeThread.run(KrollRuntime.java:112)

It could be great if someone could explain it to me where are the incompatibilities in order to make this work. I just want one label displaying this with no start/stop buttons ot something similar. Like it is mentioned above in the code snippet the label where I want the information is called: homeLabel6. I've tried aswell other options but none of them seems to suits my needs.

Answer 1

setTimeout method takes a function and duration and you are passing string in place of function setTimeout('countdown(theyear,themonth,theday)',1000);

try this:

setTimeout(function(){ countdown(theyear,themonth,theday); },1000);

or if you wants to update the text in every 1 second than you can use setInterval too like : setInterval(function(){ countdown(theyear,themonth,theday); },1000);
