android音视频通信软件的开发代码

从QQ的聊天软件开始，到现在微信的音频对讲，现在即时通讯类产品开发越来越多，不过视频类即时聊天还没有形成向腾讯这样的大巨头。最近本人也在学习Android平台下跨平台视频聊天，音视频通信开发虽然网上有很多开源项目供我们参考学习，但音视频效果很一般，还有很多不稳定的因素，毕竟是开源嘛。在国内我找到了一个比较好音视频通信解决方案（点击下载官方demo），该案例提供了纯Java语言接口供我们调用，随后我参照官方android demo程序和开发文档并结合自己的见解写了一个android音视频通信软件，200行以内代码就搞定了（难以相信吧）。其实我只是调用其相关API即可实现。以下是我自己写的Java代码，以备大家互相学习：
