几十行Java代码轻松Android平台的视频开发

2016-12-31 19:28 405 查看
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:
