android音频管理器错误

Question

我正试图将一个Shotcast直播流加载到audiomanager中，但我遇到了一个问题，它在wilfire 2.2 ofocial、wilfire 2.3 rooted、模拟器w/2.2上运行良好，而在optimus black 2.2 oficial和x10 mini pro 2.1 oficial上不工作。这是媒体播放器的bug还是什么？

代码很简单：

MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource("http://150.214.174.129:8000/");
mediaPlayer.prepare(); 
mediaPlayer.start();    

不工作时的logcat：

Answer 1

你可以试试看是否更好，但我想这与无法播放文件类型的硬件有关

MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource("http://150.214.174.129:8000/");
mediaPlayer.prepareAsync(); 
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer mp) {
        mp.start();
    }
});
