How to view pdf and doc files in the application?

Question

Android

there is a link to the pdf file on the site, how to make it possible to view it either in your application. Or that it redirects to the pdf viewer.
nav_5 transfers to the PDF viewing program.
nav_6 to the site throws, shakes and then only offers to open it.
main activity:

} else if (id == R.id.nav_5) {
            Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.uoipd.by/files/files/studentu/raspisanie/dnevnoe/5kurs.pdf" +
                    ""));
            startActivity(browserIntent);

        } else if (id == R.id.nav_6) {
            Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.uoipd.by/files/files/studentu/raspisanie/zaochnoe/Raspisanie-3k-s-21.11-po-10.12.2016%20%20.pdf" +
                    ""));
            startActivity(browserIntent);

Why don't you like the option of viewing in a third-party application?
Personally, I have this code:

try
    {
      Uri path = ContentProvider.getUri(getActivity(), order);
      Intent intent = new Intent(Intent.ACTION_VIEW);
      intent.setDataAndType(path, "application/pdf");
      intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_GRANT_READ_URI_PERMISSION);
      getActivity().startActivity(intent);
    }
    catch (ActivityNotFoundException e)
    {
      new AlertDialog.Builder(getActivity())
          .setTitle(R.string.pdf_open_error)
          .setMessage(R.string.need_pdf_application)
          .setNegativeButton(R.string.close, null)
          .show();
    }
    catch (Exception e)
    {
      toast(e.getLocalizedMessage());
      Sentry.handleException(e);
    }
