基于Platinum库的DMR实现（android）

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androidcode

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PlatinumSDK

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/UPnPControlPoint)和DLNA/UPnP设备(DLNA/UPnPDevice)，其中包括有UPnPAVMediaServer,MediaRender&ControlPoint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;    }        }

反射类：

工作线程DMRWorkThread

public class DMRWorkThread extends Thread implements IBaseEngine{private static final CommonLog log = LogFactory.createLog();private static final int CHECK_INTERVAL = 30 * 1000; private Context mContext = null;private boolean mStartSuccess = false;private boolean mExitFlag = false;private String mFriendName = "";private String mUUID = "";private RenderApplication mApplication;public DMRWorkThread(Context context){mContext = context;mApplication = RenderApplication.getInstance();}public void  setFlag(boolean flag){mStartSuccess = flag;}public void setParam(String friendName, String uuid){mFriendName = friendName;mUUID = uuid;mApplication.updateDevInfo(mFriendName, mUUID);}public void awakeThread(){synchronized (this) {notifyAll();}}public void exit(){mExitFlag = true;awakeThread();}@Overridepublic void run() {log.e("DMRWorkThread run...");while(true){if (mExitFlag){stopEngine();break;}refreshNotify();synchronized(this){try{wait(CHECK_INTERVAL);}catch(Exception e){e.printStackTrace();}}if (mExitFlag){stopEngine();break;}}log.e("DMRWorkThread over...");}public void refreshNotify(){if (!CommonUtil.checkNetworkState(mContext)){return ;}if (!mStartSuccess){stopEngine();try {Thread.sleep(200);} catch (InterruptedException e) {e.printStackTrace();}boolean ret = startEngine();if (ret){mStartSuccess = true;}}}@Overridepublic boolean startEngine() {if (mFriendName.length() == 0){return false;}int ret = PlatinumJniProxy.startMediaRender(mFriendName, mUUID);boolean result = (ret == 0 ? true : false);mApplication.setDevStatus(result);return result;}@Overridepublic boolean stopEngine() {PlatinumJniProxy.stopMediaRender();mApplication.setDevStatus(false);return true;}@Overridepublic boolean restartEngine() {setFlag(false);awakeThread();return true;}}

通过startMediaRender开启设备后就可以被外界所发现，控制点发送控制信息后

动作action的回调通过反射类PlatinumReflection的静态方法onActionReflection执行

GENA事件则通过PlatinumJniProxy类的responseGenaEvent传递

详情大家down code去了解吧
