网络改变的Android的MediaPlayer流站 [英] Android MediaPlayer streaming stops on network change
问题描述
我在流媒体使用的MediaPlayer在Android上的音频。
I am streaming audio using MediaPlayer on Android.
当从Wi-Fi设备移动到细胞网络，反之亦然，在MediaPlayer停止播放。
When the device moves from Wi-Fi to the cell network or vice-versa, the MediaPlayer stops playback.
典型地有几秒价值中的音频缓冲器，所以播放不会立即停止。
Typically there are a few seconds-worth of audio in the buffer, so playback does not cease immediately.
在理想情况下，我想拿起流不间断的播放，但我看不出如何做到这一点。
Ideally I would like to pick up the stream for uninterrupted playback, but I cannot see how to do it.
我正与托管服务器和现场广播流在两个MP3文件。
I am working with both mp3 files hosted on the server and a live broadcast stream.
推荐答案
从服务器的角度来看，改变网络模式从WiFi到3G（反之亦然），看起来就像从一个单独的IP的（客户端），一个全新的连接。
From a servers point of view, changing network mode from WiFi to 3G (visa versa), will look like a brand new connection from a separate IP's (client).
如果您是从下载的服务器不支持跟踪数据流（秒，序列号，例如，字节）（不像媒体服务器），这将不得不再次开始提供从0字节的MP3。
If the server that you are downloading from does not support tracking the stream (e.g number of seconds, sequence, byte) (unlike media-servers),It will have to start serving your mp3 from 0 byte again.
如果您的网址指向位于一个标准的HTTP服务器上的MP3文件，您的情况会会发生什么。你应该考虑使用一个媒体流服务器，所以你可以继续下载/在你选择的流。当您收到的意图，该连接丢失/恢复，您可以将您的媒体播放器到新的URL与URL中的文件位置（例如秒= 19字节= 57365）。
If your URL is pointing to a MP3 file located at a standard HTTP server, your situation will be what to expect. You should look into using a Media streaming server, so you could resume downloading/streaming at your choice. When you receive the intent that the connection is lost/resume, you could point your mediaplayer to the new URL with file-position in the URL (e.g seconds=19, bytes=57365).
不知道这是否可以帮助你，但它解释了一下怎么回事幕后。
Not sure if this helps you, but it explains a bit whats going on "behind the scenes".
