最近做DLNA音樂播放的功能，由於相關資料相對較少，官網上的英文文檔又比較難理解，導致實現這一功能花費了大量時間。今天把我的Demo分享給大家。
效果圖如下：
1，本Demo實現了DMR設備的搜索，註冊事件監聽，獲取播放信息，音量，播放暫停，進度更新等功能
2，引入cling-core-1.0.5庫，主要實現了DMC的功能
3，主要邏輯：
- 啓動一個簡單的Http服務器，給所有請求返回字節流文件，請求可以攜帶參數來指定從文件的那個地方開始下載，從而實現快進功能
- 在應用啓動時，會搜索局域網內的DMR設備，當搜索到後，將第一個設備設置爲默認播放設備
- 點擊播放時，建立與播放器的"AVTransport"的服務，給它傳送播放的URI地址，然後調用播放指令
關鍵代碼如下：
