android 音视频通信Demo

原文地址：http://blog.csdn.net/cike110120/article/details/16972371

最近学习Android平台下跨平台音视频通信开发，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（百度下载官方Anychat 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：

该Android音视频解决方案还有文字聊天、发送文件、P2P连接等非常实用的功能。对于开发者来说，能快速实现类似QQ聊天和音视频通信是令人振奋的事情。
