基於CyberGarage庫的dlna開發（android）

我們在做DLNA開發的時候都是用現有的upnp開源框架，upnp官網地址是：

http://upnp.org/

相關SDK地址爲http://upnp.org/sdcps-and-certification/resources/sdks/

 

本文闡述的是基於CyberGarage庫的DMP開發，ControlPoint是核心類

關鍵方法有search();start(),stop(),addDeviceChangeListener(DeviceChangeListener listener)

見名知意

 先上幾張效果圖：






代碼裏將ControlPoint委託給service，外部通過與service的交互來執行相關操作
