我的简单音频流应用程序在 1.6 中完美运行，而 2.1 在 2.2 中无法运行。我不知道为什么。它在模拟器上运行良好，在实际的 2.2 设备上，音频在大约 10 分钟左右后意外停止。当我在手机（HTC EVO）上查看 logcat 时，我看到：
I/HTTPStream( 65): 1358 Bytes read, progress 34346/65536
I/HTTPStream( 65): 1358 Bytes read, progress 35704/65536

I/HTTPStream( 65): 1358 Bytes read, progress 46571/65536
然后突然：
E/HTTPStream( 65): recv failed, errno = 11 (Try again)
I/HTTPDataSource( 65): Retry ... 0 times left
W/HTTPStream( 65): Calling connect()...
I/AudioHardwareQSD( 65): AudioHardware pcm playback is going to standby.

该代码基本上直接来自谷歌自己的文档“从文件或流播放”：http: //developer.android.com/guide/topics/media/index.html。
它再次在 1.6 和 2.1 以及 2.2模拟器上完美运行，但在 2.2设备上像上面一样失败。
这让我发疯，有什么想法吗？谢谢。
编辑：这是我手机上的 logcat 运行时的另一个示例，突然接收失败，服务器“消失”：

同样，在 1.6 和 2.1 以及 2.2模拟器中工作正常，只是在 2.2设备上失败，特别是在我的 HTC EVO 4G 上。请注意，这是使用信号良好的 Wi-Fi。
