基于CyberGarage库的dlna开发(android)

转载地址:http://blog.csdn.net/lancees/article/details/8477513

我们在做DLNA开发的时候都是用现有的upnp开源框架,upnp官网地址是:

http://upnp.org/

相关SDK地址为http://upnp.org/sdcps-and-certification/resources/sdks/

 

本文阐述的是基于CyberGarage库的DMP开发,ControlPoint是核心类

关键方法有search();start(),stop(),addDeviceChangeListener(DeviceChangeListener listener)

见名知意

 先上几张效果图:






代码里将ControlPoint委托给service,外部通过与service的交互来执行相关操作
