Android Question Reading Bytes with Random Access File lib

Hello, new to the forum and b4a (using it for a trainee work), I'm trying to use the RAF library to read bytes from a stream and turn it into an int (simulated with the dummy) but can't wrap my head around it's output.
At first i thought my mistake was not adding "" while assigning value to dummy, but even with those i can't uderstand the output (second column in the comments)

B4X:
Sub calc
    Dim Dummy(11) As Byte
    Dim tmp As Int
 
 
    Dummy(0) = 00000000 'prints 0           0
    Dummy(1) = 11111111 'prints  199           199
    Dummy(2) = 00100000 'prints 0             160
    Dummy(3) = 01000000 'prints 0            64
    Dummy(4) = 10000000 'prints 128         128
    Dummy(5) = 00000001 'prints 1            1
    Dummy(6) = 00000010 'prints 8            10
    Dummy(7) = 00000100 'prints 64           100
    Dummy(8) = 00001000 'prints 0             232
    Dummy(9) = 00010000 'prints 0            16
    Dummy(10) = 01000000 'prints 0           64
    Dim RAF As RandomAccessFile
    RAF.Initialize3(Dummy,False)
 
     For i = 0 To Dummy.Length
        tmp=RAF.ReadUnsignedByte(i)   ' should go from 0 to 255
        Msgbox(tmp,i)
    Next

End Sub
How does exactly the conversion and assignment work?
Thanks for your time and help, i'm sure i'll soon feel VERY stupid D:



PS: Off topic, but how can i get an array or string of 0 and 1 from one of those bytes? I need to manipulate it bit by bit
