I have built webrtc for android and have included the jar file in my project. I want to attach data channel to my PeerConnection object. On web, we do following in javascript :
sendChannel = pc.createDataChannel("sendDataChannel", {reliable: true});
or
sendChannel = pc.createDataChannel("sendDataChannel", {reliable: false});
where pc is the PeerConnection.
I want to do same in Java on Android using native webrtc code. I have little confusion. By looking at Jar file on eclipse, I could see that createDataChannel method of PeerConnection takes two arguments of type String and Init.
PeerConnection.createDataChannel(String, Init)
I could not understand what should I put in the second argument. WebRTC documentation, I found, is for web applications. I have seen the following WebRTC draft document but could not understand clearly.
http://www.w3.org/TR/webrtc/#methods-2
It would be helpful if someone can provide a small example of how it should be used.
Currently, I am trying to do this:
DataChannel dc = this.pc.createDataChannel("sendDataChannel", new DataChannel.Init());
You'd create the Init instance and manipulate the public properties before passing it to createDataChannel: https://code.google.com/p/webrtc/source/browse/trunk/talk/app/webrtc/java/src/org/webrtc/DataChannel.java#35
If you did not find "reliable" there, that is because this does not work anymore. See maxRetransmits and maxRetransmitTimeMs.
