title: webview application to scan qr code
body: <p>I have a webview app in android now my question is how do i allow this app for the webview to access the camera and to scan a qr barcode? and access it?</p>
  
  <p>I did look at <a href="https://developer.android.com/guide/webapps/webview.html" rel="nofollow noreferrer">this tutorial</a>.</p>
  
  <p>I've found some code about how to access the camera to take photo's or videos, but don't see anything about <strong>scanning qr code</strong>. </p>
  
  <p>How can I do this?</p>
