title: Access Chromebook's localhost from Android apps?
body: <p>I have a Chromebook that I've set up in Developer Mode, with a crouton-installed version of Linux running alongside.  Within the <code>Linux crouton</code>, I'm running a simple web server.</p>
  
  <p>My question is whether it's possible to access that server using any Android apps that are also running on that Chromebook?</p>
  
  <p>Android apps have been installable natively on ChromeOS for some time, but everything that I've read says that they run in some kind of sandbox.  <code>ChromeOS</code> itself is pretty tight with its firewall rules as well.</p>
  
  <p>Just to get a start, I'm trying to use the Android version of the Chrome browser to load up a page that's running on a web server in the Linux crouton.  I've tried <code>localhost</code>,<code>127.0.0.1</code>, and the Chromebook's current IP address.</p>
  
  <p>I followed the instructions at <a href="https://developer.android.com/topic/arc/index.html" rel="nofollow noreferrer">https://developer.android.com/topic/arc/index.html</a> to enable Developer Mode on the <code>Android</code> side and also, I think, loosen up those firewall rules on the <code>ChromeOS</code> side.</p>
  
  <p>Is there some secret sauce that I'm missing?  Is this even possible at all?</p>
