HI Siji. Have you tried this aproach? public void convert(){
ByteArrayInputStream imageStream = new ByteArrayInputStream(data); Bitmap theImage = BitmapFactory.decodeStream(imageStream); try { File file = FotoFolder.getFotoFile("fileName.png"); FileOutputStream out = new FileOutputStream(file); theImage.compress(Bitmap.CompressFormat.PNG, 100, out); out.flush(); out.close(); } catch (Exception e) { e.printStackTrace(); } } 2011/9/15 Siji T G <s...@techgentsia.com> > > I am trying to decode ARGB byte array into bitmap to display it as an > image view.
