    private void bytesToImageFile(byte[] bytes) {
        try {
            File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/facenew1.png");
            FileOutputStream fos = new FileOutputStream(file);
            fos.write(bytes, 0, bytes.length);
            fos.flush();
            fos.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
