I have done my custom media player for streaming audio file from server but i don't know how to add the background service to this media player and like to add in the notification bar too from which we can control and close the audio player itself. Please tell me anyone how to make a service for custom streaming - audio player.

My Code Part :

public class AudioStream extends Activity implements View.OnClickListener,
 OnTouchListener, OnCompletionListener, OnBufferingUpdateListener,
 OnPreparedListener, SeekBar.OnSeekBarChangeListener, OnErrorListener, OnInfoListener 

private ImageButton buttonPlayPause;
private SeekBar seekBarProgress;
private MediaPlayer mediaPlayer;
private TextView totalDuration, currentDuration;
private Handler mHandler;
private int mediaFileLengthInMilliseconds;
private Utils utils;
private String streamUrl, thumbImgUrl;

@Override
protected void onCreate(Bundle savedInstanceState) 
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_audio_stream);

 // Getting Stream Url from the preview activity
 if(getIntent()!= null)
 streamUrl = getIntent().getStringExtra("normalurl");
 thumbImgUrl = getIntent().getStringExtra("thumburl");
 
 initView();



/** This method initialise all the views in project */
private void initView() 

 // this handler using for update the seekbar progress and current time duration of the file
 mHandler = new Handler();
 utils = new Utils();

 buttonPlayPause = (ImageButton) findViewById(R.id.ButtonTestPlayPause);
 buttonPlayPause.setOnClickListener(this);

 seekBarProgress = (SeekBar) findViewById(R.id.SeekBarTestPlay);
 seekBarProgress.setMax(99); // It means 100% .0-99
 seekBarProgress.setOnTouchListener(this);

 currentDuration = (TextView) findViewById(R.id.musicCurrentLoc);
 totalDuration = (TextView) findViewById(R.id.musicDuration);

 mediaPlayer = new MediaPlayer();

 // start the asyntask to start the streaming and start the player
 AudioStreamingAsyntask audioAsyn = new AudioStreamingAsyntask();
 audioAsyn.execute(streamUrl);

 seekBarProgress.setOnSeekBarChangeListener(this);
 mediaPlayer.setOnPreparedListener(this);
 mediaPlayer.setOnCompletionListener(this);
 mediaPlayer.setOnBufferingUpdateListener(this);
