Streaming Audio from A URL in Android using MediaPlayer?

Question

I\'ve been trying to stream mp3\'s over http using Android\'s built in MediaPlayer class. The documentation would suggest to me that this should be as easy as :

Answer 1

I guess that you are trying to play an .pls directly or something similar.

try this out:

1: the code

mediaPlayer = MediaPlayer.create(this, Uri.parse("http://vprbbc.streamguys.net:80/vprbbc24.mp3"));
mediaPlayer.start();

2: the .pls file

This URL is from BBC just as an example. It was an .pls file that on linux i downloaded with

wget http://foo.bar/file.pls

and then i opened with vim (use your favorite editor ;) and i've seen the real URLs inside this file. Unfortunately not all of the .pls are plain text like that.

I've read that 1.6 would not support streaming mp3 over http, but, i've just tested the obove code with android 1.6 and 2.2 and didn't have any issue.

good luck!

Answer 2

No call mp.start with an OnPreparedListener to avoid the zero state i the log..

Answer 3

Looking my projects:

1. https://github.com/master255/ImmortalPlayer http/FTP support, One thread to read, send and save to cache data. Most simplest way and most fastest work. Complex logic - best way!
2. https://github.com/master255/VideoViewCache Simple Videoview with cache. Two threads for play and save data. Bad logic, but if you need then use this.

simple Media Player with streaming example.For xml part you need one button with id button1 and two images in your drawable folder with name button_pause and button_play and please don't forget to add the internet permission in your manifest.

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;
        }
    }
};

Answer 5

I've had the same error as you have and it turned out that there was nothing wrong with the code. The problem was that the webserver was sending the wrong Content-Type header.

Try wireshark or something similar to see what content-type the webserver is sending.

Use

 mediaplayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
 mediaplayer.prepareAsync();
 mediaplayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
      @Override
      public void onPrepared(MediaPlayer mp) {
          mediaplayer.start();
      }
 });
