Android Question How do I count set bits in a byte?

How do I count set bits in a byte? Example: 0x12 is 00010010 so it should return 2

I don't know any built-in function to count bits. You can use this Sub

Sub CountSetBits( dataByte As Byte) As Int
   Dim k, bitCount As Int
   For k=0 To 7
      If Bit.And( dataByte, Bit.ShiftLeft(1, k) )<>0 Then bitCount = bitCount+1
   Next
   Return bitCount
End Sub
