手機上的音頻文件流式傳輸

Question

如何通過我們自己的服務器通過Android應用在手機上播放和流式傳輸音頻文件。他們都位於相同的無線網絡。但音頻文件只存在於服務器上。有沒有辦法在客戶端Android上流式傳輸這些文件（soundcloud）

Answer 1

我已經streamed music to my phone with ES File Explorer and a SAMBA share過去。然而，該帖子中的其他選項聽起來像甚至是更好的選項。

Answer 2

Videoview還可以播放音頻文件。像這樣嘗試。

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 3

通過使用AsyncTask，您可以流式傳輸音頻文件。

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; 
    } 
} 
};
