How do I get difference between two dates in android?, tried every thing and post

Question

I saw all the post in here and still I can\'t figure how do get difference between two android dates.

This is what I do:

long diff = date1.getTime()          


        

Answer 1

shortest answer that works for me. send start and end date in millisecond.

public int GetDifference(long start,long end){
    Calendar cal = Calendar.getInstance();
    cal.setTimeInMillis(start);
    int hour = cal.get(Calendar.HOUR_OF_DAY);
    int min = cal.get(Calendar.MINUTE);
    long t=(23-hour)*3600000+(59-min)*60000;

    t=start+t;

    int diff=0;
    if(end>t){
        diff=(int)((end-t)/ TimeUnit.DAYS.toMillis(1))+1;
    }

    return  diff;
}
