Dlna音乐播放器

最近做DLNA音乐播放的功能，由于相关资料相对较少，官网上的英文文档又比较难理解，导致实现这一功能花费了大量时间。今天把我的Demo分享给大家。

效果图如下：

1，本Demo实现了DMR设备的搜索，注册事件监听，获取播放信息，音量，播放暂停，进度更新等功能

2，引入cling-core-1.0.5库，主要实现了DMC的功能

3，主要逻辑：

• 启动一个简单的Http服务器，给所有请求返回字节流文件，请求可以携带参数来指定从文件的那个地方开始下载，从而实现快进功能
• 在应用启动时，会搜索局域网内的DMR设备，当搜索到后，将第一个设备设置为默认播放设备
• 点击播放时，建立与播放器的"AVTransport"的服务，给它传送播放的URI地址，然后调用播放指令

关键代码如下：

一、DMC控制部分

	private static final UDAServiceType AV_TRANSPORT_TYPE = new UDAServiceType("AVTransport");
	private static final UDAServiceType RENDERING_CONTROL_TYPE = new UDAServiceType("RenderingControl");

        if (service == null) return;
        ActionCallback actionCallback = new SetAVTransportURI(service, path) {
            @Override
            public void failure(ActionInvocation paramActionInvocation, UpnpResponse paramUpnpResponse, String paramString) {
               // Current state of service prevents invoking that action. Connection error or no response received.
            	Log.w("Dlna", "--- SetAVTransportURI failure() paramString = " + paramString);
                if(callback != null) callback.onFailare(paramActionInvocation, paramUpnpResponse, "SetAVTransportURI " + paramString);

二、在绑定到AndroidUpnpServiceImpl服务后，开始搜索设备

<span style="font-size:18px;">// AndroidUpnpService绑定后的监听，绑定成功或失败后的处理
	private ServiceConnection serviceConnection = new ServiceConnection() {

		public void onServiceConnected(ComponentName className, IBinder service) {
			Log.i(TAG, "ServiceConnection onServiceConnected()...");
			upnpService = (AndroidUpnpService) service;
			isServiceConnected = true;

			searchDMR();
		}

		public void onServiceDisconnected(ComponentName className) {
			upnpService = null;
		}
	};

	// 搜索DMR设备
	private void searchDMR() {
		dmrDeviceManager.removeAllDevices();
		dmrDeviceManager.searchDmrDevices(new OnSearchDmrDeviceListener() {

			@Override
			public void onDeviceRemove(final DmrDevice device) {
				Log.i(TAG, "dmrDeviceManager.searchDmrDevices() onDeviceRemove " + device.getName());
				dmrDevicesList.remove(device);
			}

			@Override
			public void onDeviceAdd(final DmrDevice device) {
				Log.i(TAG, "dmrDeviceManager.searchDmrDevices() onDeviceAdd " + device.getName());
				dmrDevicesList.add(device);
				// 判断第一次，初始化设置一个设备
				if(curDmrDevice == null){
					setCurDmrDevice(dmrDevicesList.get(0));
					runOnUiThread(new Runnable() {
						
						@Override
						public void run() {
							btRender.setText("Render ( " + curDmrDevice.getName() + " ) ");
						}
					});
				}
			}
		});
	}</span>
