如何使官方提供的AppRTCDemo 运行在自己搭建的server（官方提供的apprtc）上（官方的server源码）

I am developing a chat application and done with it. Now I want to implement video chat also. After research a lot I decided to go with "WebRTC" library.

What I have done?

1) Able to run AppRtcDemo at local server and Its working fine between browsers.

Reference : http://www.webrtc.org/reference/getting-started

2) Able to build Android AppRtcDemo.But when I run it say "Cross origin does not support".

After research I found in webrtc discussion that to resolve this issue I need to set-up own turn server.

3) So I install latest rfc5766TurnServer recommended by webrtc. I got success to run turn server.

Reference : http://code.google.com/p/rfc5766-turn-server/

I do following changes to ApprtcDemo (web) and (Android) to work with my Turn server

1) apprtc.py

Replace:

turn_url = ‘https://computeengineondemand.appspot.com/‘
turn_url = turn_url + ‘turn?‘ + ‘username=‘ + user + ‘&key=4080218913‘

With point to my turn server:

turn_url = ‘http://192.168.5.85:3478/?service=turn&username=biraj‘

2) index.html

Replace:

var pcConfig = {{ pc_config|safe }};

With:

var pcConfig = {"iceServers": [{"url": "stun:stun.l.google.com:19302"},            {"url":"turn:biraj@192.168.5.85:3479", "credential":"0x5b04123c3eec4cf0be64ab909bb2ff5b"}]};

Android

1)AppRTCDemoActivity.java

Replace:

roomInput.setText("https://apprtc.appspot.com/?r=");

With my local apprtc server:

roomInput.setText("http://192.168.5.86:8080/?r=");

2) AppRTCClient.java

In private PeerConnection.IceServer requestTurnServer(String url){} function

Replace:

connection.addRequestProperty("origin", "https://apprtc.appspot.com");

With:

connection.addRequestProperty("origin", "http://192.168.5.86:8080");

3) /assets/channel.html

Replace:

<script src="https://apprtc.appspot.com/_ah/channel/jsapi"></script>

With:

<script src="http://192.168.5.86:8080/_ah/channel/jsapi"></script>

Now my question is why this is working between browsers but not between android AppRtcDemo and browser.

When I run AppRtcDemo on android after doing above changes local camera preview is started at right-top corner and message prompt "waiting for ICEcandidates" then nothing happens.

Thanks in advance.

Thanks to All for supporting my question.After long rocky ride with ApprtcDemo I got success and it works fine.I am posting the solution.

Find the "GAEChannelClient.java" java file.

and do change as below.
