最近在做Android 视频相关开发。视频一直转圈圈，就是不播放处理，同时出现以下error。 (如果等一等，视频会播放出来，目前还不知道时怎么回事)
1 V/MediaHTTPService: makeHTTPConnection: CookieHandler (java.net.CookieManager@722a3eb) exists.
2 makeHTTPConnection(android.media.MediaHTTPService@d8c21eb): cookieHandler: java.net.CookieManager@722a3eb Cookies: null
3 E/HttpProxyCacheServer: HttpProxyCacheServer error
