Android Question GetBlob (SQL) has negativ values (I'm confused)

I'm confused: Bytearray from GetBlob (SQL) has negativ values
buffer=cCursor2.GetBlob("vBlob")
something like: -119,80,78,71,13,10,26,10,0,0,0,13,73,72,68,82,0,0,2,-68,0,0,2,-87,8,6,0,0,0,94,....

I want to tranfer the blob via json and there is service (vb.net) to handle the json.
But it can't handle negative Bytes.

What am I doing wrong?
Or what is the best way to transfer blobs via json?

B4X:

Dim ub(buffer.Length) As Int
For i = 0 to buffer.Length - 1
 ub(i) = Bit.And(0xFF, buffer(i))
