  5. I think your approach is very useful, however it might be enhanced in terms of security.

    Don't you think it is better to use a startActivityForResult to get the restrieved Result from scan and handle this in MainActivity instead of using a public variable ?

  6. By clicking on Scan qr button,it is redirecting to next page,but the camera is not opening,can I know why?
