Android Question 0xFO in arrary : -16 (0xFFFFFFF0)

Lello1964 said:

I need to build an array of bytes containing hexadecimal values: (0x32, 0xF0, 0xE0). When I insert the values into the array, I get:
50 (0x32)
-16 (0xFFFFFFF0)
-32 (0xFFFFFFE0)

Instead, I need them to remain in the original format: (0x32, 0xF0, 0xE0).

I tried using

B4X:

 Messaggio() As Byte = ARRAY AS BYTE(0x32, Bit.And(0xF0, 0xFF), Bit.And(0xE0,0xFF))

but it doesn't work.

Do you have a solution?

    Dim Messaggio() As Byte = Array As Byte(0x32, 0xf0, 0xe0)
    Dim bc As ByteConverter
    Log(bc.HexFromBytes(Messaggio)) '32F0E0' see they are correct
    For Each b As Byte In Messaggio
        Log(Bit.And(b, 0xff)) '50 240 224'
    Next
