我正在尝试将InputStream的数据流式传输到充当代理的套接字。原因是，我想通过android InputStreams播放MediaPlayer。
问题是我总是得到 endto失败：ECONNRESET（由对等方重置连接）异常：

问题
我该如何解决？我的解决方案是附加的，基于https://code.google.com/p/npr-android-app/source/browse/Npr/src/org/npr/android/news/StreamProxy.java ...我发现我可能需要一个标题来保持套接字打开，但我真的不知道这是不是真的以及如何将它添加到我的解决方案中..
我的自定义类IDownloadableMedia只是直接返回一个简单的流...
我有多个视频源，其中一些仅允许流。为了测试我也使用了一个与url一起使用的源代码，我在下载函数中创建了一个InputStream，如下所示：new URL(url).openStream()。网址有效且有效！
