最近在做Android 視訊相關開發。視訊一直轉圈圈，就是不播放處理，同時出現以下error。 (如果等一等，視訊會播放出來，目前還不知道時怎麼回事)

 1 V/MediaHTTPService: makeHTTPConnection: CookieHandler (java.net.CookieManager@722a3eb) exists.
 2     makeHTTPConnection(android.media.MediaHTTPService@d8c21eb): cookieHandler: java.net.CookieManager@722a3eb Cookies: null
