Getting a null pointer exception while calling getTimeStamp from firebase database

Question

The first time i run the app after uninstalling & reinstalling sometimes it crashes due to

 viewHolder.setTimestamp(DateUtils.getRelativeTimeSpanString((long) model.getTimestamp()).toString());

giving an error

Exception java.lang.NullPointerException: Attempt to invoke virtual method 'long java.lang.Long.longValue()' on a null object reference

what should i do to solve this issue as after crashing once the next time everything works fine.If you need more codes to guide me then just ask.

`model.getTimestamp()` is returning null. You can't pass null to primitives or casting null to primitives. — mihail, Apr 03 '17 at 07:14

you can use it in try catch like this way.

try
{
viewHolder.setTimestamp(DateUtils.getRelativeTimeSpanString((long) model.getTimestamp()).toString());
}
catch(Exception e)
{
}
