MediaPlayer

# Basic creation and playing #

MediaPlayer class can be used to control playback of audio/video files and streams.

Creation of MediaPlayer object can be of three types:

1. Media from local resource

   MediaPlayer mediaPlayer = MediaPlayer.create(context, R.raw.resource);
   mediaPlayer.start(); // no need to call prepare(); create() does that for you

2. From local URI (obtained from ContentResolver)

   Uri myUri = ….; // initialize Uri here
   MediaPlayer mediaPlayer = new MediaPlayer();
   mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
   mediaPlayer.setDataSource(getApplicationContext(), myUri);
   mediaPlayer.prepare();
   mediaPlayer.start();

3. From external URL

   String url = “http://……..”; // your URL here
   MediaPlayer mediaPlayer = new MediaPlayer();
   mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
   mediaPlayer.setDataSource(url);
   mediaPlayer.prepare(); // might take long! (for buffering, etc)
   mediaPlayer.start();

Media Player with buffer progress and play position

public class SoundActivity extends Activity  {

private MediaPlayer mediaPlayer;
ProgressBar progress_bar;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tool_sound);
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
progress_bar = (ProgressBar) findViewById(R.id.progress_bar);

btn_play_stop.setEnabled(false);
btn_play_stop.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if(mediaPlayer.isPlaying()) {
mediaPlayer.pause();
btn_play_stop.setImageResource(R.drawable.ic_pause_black_24dp);
} else {
mediaPlayer.start();
btn_play_stop.setImageResource(R.drawable.ic_play_arrow_black_24px);
}
}
});

mediaPlayer.setDataSource(proxyUrl);
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
observer.stop();
progress_bar.setProgress(mp.getCurrentPosition());
// TODO Auto-generated method stub
mediaPlayer.stop();
mediaPlayer.reset();
}
});
mediaPlayer.setOnBufferingUpdateListener(new MediaPlayer.OnBufferingUpdateListener() {
@Override
public void onBufferingUpdate(MediaPlayer mp, int percent) {
progress_bar.setSecondaryProgress(percent);
}
});
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
btn_play_stop.setEnabled(true);

}
});
observer = new MediaObserver();
mediaPlayer.prepare();
mediaPlayer.start();
new Thread(observer).start();
}


private MediaObserver observer = null;

private class MediaObserver implements Runnable {
private AtomicBoolean stop = new AtomicBoolean(false);

public void stop() {
stop.set(true);
}

@Override
public void run() {
while (!stop.get()) {
progress_bar.setProgress((int)((double)mediaPlayer.getCurrentPosition() / (double)mediaPlayer.getDuration()*100));
try {
Thread.sleep(200);
} catch (Exception ex) {
Logger.log(ToolSoundActivity.this, ex);
}

}
}
}

@Override
protected void onDestroy() {
super.onDestroy();
mediaPlayer.stop();
}
}
