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.
