Question

我正在尝试开发一个Android应用程序，它将支持与其他同行的音频。

信令应该按照这个原则工作。 https://developers.google.com/talk/call_signaling

我在项目中包含了libjingle_peerconnection.jar。我可以成功地从另一个使用libjingle构建的PC应用程序（通过xmpp服务器）接收IQ数据包。

e.g

<jingle xmlns='urn:xmpp:jingle:1' action='session-initiate' initiator='john....@testing.stuff.com' responder='par.mueller@testing.stuff..com/Smack' sid='GUV3WncaSdoPhQFF'>
<content creator='initiator' name='Audio'>

    </encryption></description></content></jingle></iq></body>

我收到会话后发起+ transport-info数据包，我可以创建自己的数据包信息并发回给主叫方。

我假设我应该使用libjingle_peerconnection.jar中的类并提取我需要的信息。但是我该怎么做？

XEP-0167，libjingle_peerconnection.jar和我的应用程序
