我确信之前已经问过这个问题,但我一直无法找到答案。我正在尝试从服务器加载流式音频。它是一个音频/ aac文件
http://3363.live.streamtheworld.com:80/CHUMFMAACCMP3
我正在使用的代码是
private void playAudio(String str) {
try {
final String path = str;
if (path == null || path.length() == 0) {
Toast.makeText(RadioPlayer.this, "File URL/path is empty",
Toast.LENGTH_LONG).show();
} else {
// If the path has not changed, just start the media player
MediaPlayer mp = new MediaPlayer();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
try{
mp.setDataSource(getDataSource(path));
mp.prepareAsync();
mp.start();
}catch(IOException e){
Log.i("ONCREATE IOEXCEPTION", e.getMessage());
}catch(Exception e){
Log.i("ONCREATE EXCEPTION", e.getMessage());
}
}
} catch (Exception e) {
Log.e("RPLAYER EXCEPTION", "error: " + e.getMessage(), e);
}
}
private String getDataSource(String path) throws IOException {
if (!URLUtil.isNetworkUrl(path)) {
return path;
} else {
URL url = new URL(path);
URLConnection cn = url.openConnection();
cn.connect();
InputStream stream = cn.getInputStream();
if (stream == null)
throw new RuntimeException("stream is null");
File temp = File.createTempFile("mediaplayertmp", ".dat");
temp.deleteOnExit();
String tempPath = temp.getAbsolutePath();
FileOutputStream out = new FileOutputStream(temp);
byte buf[] = new byte[128];
do {
int numread = stream.read(buf);
if (numread <= 0)
break;
out.write(buf, 0, numread);
} while (true);
try {
stream.close();
} catch (IOException ex) {
Log.e("RPLAYER IOEXCEPTION", "error: " + ex.getMessage(), ex);
}
return tempPath;
}
}
这是正确的实施吗?我不确定我哪里出错了。请有人请帮助我。

方法prepareAsync()
是异步的 - 引用文档:
以异步方式准备播放器以进行播放。
您需要致电setOnPreparedListener()
,提供MediaPlayer.OnPreparedListener
。然后,在该听众的onPrepared()
中,您可以拨打start()
。

不支持AAC流式传输格式,您不能直接在Android版本低于2.2的情况下播放Shoutcast流。
