title: arc welder no internet connection through proxy
body: <p>I used arc welder (<a href="https://developer.chrome.com/apps/getstarted_arc" rel="nofollow">https://developer.chrome.com/apps/getstarted_arc</a>) to make an Chrome app out of an Android app, and everything is fine until I try to get an Internet connection behind proxy in the Chrome app. 
  It connects to the Internet fine, when there's no proxy. But I can't find any proxy settings to fill in, and apparently it doesn't use Chrome's settings for this (I use Chrome behind a proxy with no problems).
  Is it possible to get Internet connection in an arc welder app behind proxy??
  Thanks</p>
