        int width = bitMatrix.getWidth();
        int height = bitMatrix.getHeight();
        Bitmap bmp = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565);
        for (int x = 0; x < width; x++) {
            for (int y = 0; y < height; y++) {
// set colors for QR code
                bmp.setPixel(x, y, bitMatrix.get(x, y) ? Color.BLACK : Color.WHITE);
            }
        }
        ((ImageView) findViewById(R.id.img_result_qr)).setImageBitmap(bmp);

        e.printStackTrace();
