title: Access an external USB camera from the webview in Android
body: <p>I have a webview in my Android app. From the webview, I am able to access default camera on the phone.  The following code works fine.</p>
  
  <pre><code>webview.setWebChromeClient(new WebChromeClient(){
      // Need to accept permissions to use the camera
      @Override
      public void onPermissionRequest(final PermissionRequest request) {
          L.d("onPermissionRequest");
          request.grant(request.getResources());
      }
  });
  </code></pre>
  
  <p>My issue is to access an external USB camera from this webview. Above permission opens up the default camera in the webview. </p>
  
  <p>I haven't been able to find any documentation which even  says this thing is possible. Is it because of some security issue ?</p>
