Sorry for late review.
Do we really need to set a long value? I cannot believe that
long value is repeated in the page. Value repeatition is
usually done by value 0 or 1 and it's enough to use int. And, I heard
that value 0 or 1 is repeated in Android. Could you check the distribution
of the value in the same page?
Thanks.
