打开 .pls 链接：

 public ArrayList<String> readURLs(String url) {             
            if(url == null) return false;
            ArrayList<String> allURls = new ArrayList<String>();
            try {

                URL urls = new URL(url);
                BufferedReader in = new BufferedReader(new InputStreamReader(urls
                        .openStream()));
                String str;
                while ((str = in.readLine()) != null) {
                    allURls.add(str);
                }
                in.close();
                return allURls ;
            } catch (Exception e) {
                e.printStackTrace();
                return null;
            } 
        }

然后解析链接并播放。

http://stream.radiosai.net:8002/ 这个 Shoutcast 类型。链接仅在 android 2.2+ 上打开！！！

Answer 3

http://stream.radiosai.net:8002/ 不是有效的媒体文件，它是一个网站（html 文件）。

还要检查 Android 是否支持媒体格式： http://developer.android.com/guide/appendix/media-formats.html
