接上篇博文：基于CyberGarage库的dlna开发（android）

文章讲述了用CyberGarage库的DMP实现

部分童鞋想知道DMR是如何实现的

网上似乎也没看到相关的android code

在下不才，自个儿捣鼓了project并上传至github

今与诸君共赏

本例所采用的upnp框架是Platinum SDK

官方网址是http://www.plutinosoft.com/platinum

该库是一个跨平台的C++库，利用该库，可以很容易就构建出DLNA/UPnP控制点 (DLNA/UPnP Control Point)和DLNA/UPnP设备(DLNA/UPnP Device)，其中包括有UPnP AV Media Server, Media Render & Control Point的例子

该库稳定强大，被很多知名产品所沿用，口碑较好自然也为楼主所青睐

关于该库如何编译，请参考这篇博文：NDK下将Platinum SDK 编译成so库

下面给出运行效果图：

JNI接口文件：

public class PlatinumJniProxy {

    static {
        System.loadLibrary("git-platinum");
    }   

    public static native int startMediaRender(byte[] friendname ,byte[] uuid);
    public static native int stopMediaRender();  
    public static native boolean responseGenaEvent(int cmd, byte[] value ,byte[] data);  
    public static native boolean enableLogPrint(boolean flag);


    public static  int startMediaRender(String friendname ,String uuid){
        if (friendname == null)friendname = "";
        if (uuid == null)uuid = "";
        int ret = -1;
        try {
            ret = startMediaRender(friendname.getBytes("utf-8"), uuid.getBytes("utf-8"));
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        return ret;
    }

    public static  boolean responseGenaEvent(int cmd, String value, String data){
        if (value == null)value = "";
        if (data == null)data = "";
        boolean ret = false;
        try {
            ret = responseGenaEvent(cmd, value.getBytes("utf-8"), data.getBytes("utf-8"));
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        return ret;
    }


}
