      Resources res = getResources();
      InputStream in_s = res.openRawResource(R.raw.help);
  
      byte[] b = new byte[in_s.available()];
      in_s.read(b);
      txtHelp.setText(new String(b));
  } catch (Exception e) {
      // e.printStackTrace();
      txtHelp.setText("Error: can't show help.");
  }
