android - 在android中流式传输音频.pls

Question

我正在制作一个使用流式传输的类似 radio 的应用程序。在这里，我需要从链接 (http://somedomain/some.pls) 流式传输音频。

我已经创建了 MediaPlayer 并且知道如何播放音频文件。但不知道如何从网上流式传输。

编辑: 我使用以下代码时得到的 logcat

MediaPlayer mp = new MediaPlayer();  
mp.setDataSource(http://somedomain/some.pls);
mp.prepare();
mp.start()

这个 02-15 05:50:16.509: VERBOSE/PlayerDriver(2393): HandleInformationalEvent: 20 循环但没有声音..
可能有什么问题..
谢谢。

Answer 1

您可以使用 MediaPlayer 类上提供的文件流功能来执行上述操作。
我没有测试下面的代码，但它应该是这些行:

MediaPlayer mp = new MediaPlayer();  
mp.setDataSource(http://somedomain/some.pls);
mp.prepare();
mp.start();  

但请记住执行以下操作:
1. 用 try 和 catch 语句包围上面的每个语句，并大量打印到 LogCat。这将有助于轻松调试。
2. 完成后释放资源。
