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android code
有鉴于此，蓝老师特地捣鼓了project并上传至github
希望对童鞋们有帮助~
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;
}
}
反射类：
public class PlatinumReflection {
private static final CommonLog log = LogFactory.createLog();

if (mListener != null){
mListener.onActionInvoke(cmd, value, data);
}
}
public static void setActionInvokeListener(ActionReflectionListener listener){
mListener = listener;
}
}
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();
}
@Override
public 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;
}
}
}
@Override
public 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;
}
@Override
public boolean stopEngine() {
PlatinumJniProxy.stopMediaRender();
mApplication.setDevStatus(false);
return true;
}
@Override
public 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
