I think you need to extract remainders from each of your divisions, using the mod (%) operator.

How about this:

final long SEC_PER_DAY = 24 * 60 * 60;
final long SEC_PER_HOUR = 60 * 60;
final long SEC_PER_MIN = 60;

public void onTick(long millis) {
    long tot_sec   = millis/1000;
    long rem_days  = tot_sec / SEC_PER_DAY;
    long rem_hours = (tot_sec % SEC_PER_DAY) / SEC_PER_HOUR;
    long rem_mins  = ((tot_sec % SEC_PER_DAY) % SEC_PER_HOUR) / SEC_PER_MIN;
    long rem_secs  = ((tot_sec % SEC_PER_DAY) % SEC_PER_HOUR) % SEC_PER_MIN;

    // and then format as you please...
}

you should use DateFormat or SimpleDateFormat, see http://developer.android.com/reference/java/text/DateFormat.html

First, you should convert your milliseconds to Date.

Date date = new Date();
date.setTime(millis);

Then you could use DateFormat to format your timestamp to human-readable string.

How can I convert a date in this format day/mounth/year to milliseconds ? – MimmoG Apr 17 '12 at 09:32
I guess you could use Date.setYear/Date.setMonth etc. – mariotaku Apr 17 '12 at 12:46
