移动设备上的音频文件流式传输

Question

如何通过我们自己的服务器通过安卓应用在移动设备上播放和流式传输音频文件。它们都位于同一个wifi网络中。但是音频文件只存在于服务器上。有没有办法像（soundcloud）一样在客户端android上流式传输这些文件

Answer 1

Videoview 也可以播放音频文件。试试这样。

String urlAudio=""  // your server audio url path
 videoView = (VideoView) viewRoot.findViewById(R.id.VideoView);
  mediaController = new MediaController(getActivity());
    mediaController.setAnchorView(videoView);
    videoView.setMediaController(mediaController);

videoView.setVideoURI(Uri.parse(urlAudio));
    videoView.requestFocus();
    videoView.start();

Answer 2

我过去曾streamed music to my phone with ES File Explorer and a SAMBA share。然而，该帖子中的其他选项听起来像是更好的选择。

通过使用 AsyncTask，您可以流式传输音频文件。

public class MainActivity extends Activity {
private Button btn;
/**
 * help to toggle between play and pause.
 */
private boolean playPause;
private MediaPlayer mediaPlayer;
/**
 * remain false till media is not completed, inside        OnCompletionListener     make it true.
 */
private boolean intialStage = true;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    btn = (Button) findViewById(R.id.button1);
    mediaPlayer = new MediaPlayer();
    mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
    btn.setOnClickListener(pausePlay);

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is   present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

private OnClickListener pausePlay = new OnClickListener() {

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    // TODO Auto-generated method stub

    if (!playPause) {
        btn.setBackgroundResource(R.drawable.button_pause);
        if (intialStage)
            new Player()
                    .execute("http://www.virginmegastore.me/Library/Music/CD_001214/Tracks/Track1.mp3");
        else {
            if (!mediaPlayer.isPlaying())
                mediaPlayer.start();
        }
        playPause = true;
    } else {
        btn.setBackgroundResource(R.drawable.button_play);
        if (mediaPlayer.isPlaying())
            mediaPlayer.pause();
        playPause = false;
    }
}
};
