Vincent, You do realise, that the values you showed in your example are half-bytes?
The problem you are trying to solve is not too hard. For each byte received keep detecting the leftmost bit using binary AND operator and appropriate mask. Once you detect 1 add 'black pixel bytes' into your traget byte array. Upon detecting 0 add 'white pixel bytes'. Then binary shift the source data left and repeat detecting the leftmost bit again. Do this in a loop. If your bytes have values 0-15 you will have to shift left by 4 positions before starting to analyse the input. Once your target byte array is ready, use BitmapFactory as suggested by Streets of Boston.
