title: getting net::ERR_CONNECTION_REFUSED (http://localhost:8080) on android 4.4.2 version
body: <p>I build a simple ionic project from <a href="https://www.djamware.com/post/58e657b680aca764ec903c2d/ionic-3-and-angular-4-mobile-app-example" rel="noreferrer">this tutorial.</a></p>
  
  <p>It runs on Xiaomi Mix 2 phone (android version 8.0.0) and on browser without any problem.
  But when I deployed to the samsung note 2 (android version 4.4.2), 
  it gives an application error with this message:
  <strong>net::ERR_CONNECTION_REFUSED (<a href="http://localhost:8080" rel="noreferrer">http://localhost:8080</a>)</strong></p>
  
  <p>Why am I getting this error?</p>
  
  <p>Any advice and suggestions will be appreciated.</p>
