title: Building an Apprtc for native android with nodejs server
body: <p>I've successfully build the AppRTC for native android by taking code from <a href="https://github.com/njovy/AppRTCDemo" rel="nofollow noreferrer">https://github.com/njovy/AppRTCDemo</a>
   and I'm able to make videocalls providing the address of the demo app ( <a href="https://apprtc.appspot.com/?r=XXXXXXXX" rel="nofollow noreferrer">https://apprtc.appspot.com/?r=XXXXXXXX</a> ). Now I have install the nodejs 
  and also run the node static server in my system. I also know that to run the app on my local server we have remove Google TURN server. But how to bypass this turn server. I have also read this <a href="https://stackoverflow.com/questions/21085261/apprtcdemo-with-local-server-works-between-browsers-but-not-android-native-to-br">ApprtcDemo with local server works between browsers but not Android native to browser</a> but can't able to understand clearly.</p>
  
  <p>The problem is that what I need to make change in my code and how to install turn server for node server so that android can connect to my local server. How to manage the setup of turn server in <code>Centos7</code> and what is apprtc.py</p>
  
  <p>I am new to this and does not have much knowledge of server so if i have asked anything wrong so ignore it  but please reply me.</p>
  
  <p>After lots of effort i have install the turn server by following the link <a href="https://www.webrtc-experiment.com/docs/TURN-server-installation-guide.html" rel="nofollow noreferrer">https://www.webrtc-experiment.com/docs/TURN-server-installation-guide.html</a> </p>
  
  <p>Now i have to change the url in my code but i can't able figure what and where to make change in Apprtc demo sample for native android</p>
