Getting time diff from timestamp in Java
You have a timestamp and you want to get the difference in string like the folowing: 10 sec ago 3 minute ago 7 days ago and so on. The following function does it. private String getTimeDiff( long timestamp){ String timeDiffStr = "" ; Calendar cal = Calendar.getInstance(); long currentTimeInMillis = cal.getTimeInMillis(); long timeDiff = (currentTimeInMillis - timestamp) / 1000; if (timeDiff < 60){ timeDiffStr = timeDiff + " seconds ago" ; return timeDiffStr; } timeDiff = timeDiff / 60; if (timeDiff < 60){ timeDiffStr = timeDiff + " minutes ago" ; return timeDiffStr; } timeDiff = timeDiff / 60; // in hours if (timeDiff < 24){ timeDiffStr = timeDiff + " hours ago" ; return timeDiffStr; } timeDiff = timeD
