super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

btn1= (Button)findViewById(R.id.button1);

btn2= (Button)findViewById(R.id.button2);

btn3=(Button) findViewById(R.id.button3);

mp = MediaPlayer.create(MainActivity.this, R.raw.bejuban);

tv1=(TextView) findViewById(R.id.textView1);

tv2=(TextView) findViewById(R.id.textView2);

sb=(SeekBar)findViewById(R.id.seekBar1);

sb.setMax(mp.getDuration());

SeekUpdation();

btn1.setOnClickListener( new View.OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

SeekUpdation();

if(mp==null)

mp = MediaPlayer.create(MainActivity.this, 

R.raw.bejuban);

mp.start();

sb.setMax(mp.getDuration());

sb.setProgress(mp.getCurrentPosition());

}

});

btn2.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

if(mp!=null)

{

mp.pause();

sb.setProgress(mp.getCurrentPosition());

}

}

});

btn3.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

if(mp!=null)

{

mp.stop();

sb.setProgress(mp.getDuration());

mp=null;

}

Toast.makeText(MainActivity.this, " MEdia STopped", 

Toast.LENGTH_SHORT).show();

}

});

sb.setOnSeekBarChangeListener( new 

SeekBar.OnSeekBarChangeListener() {

@Override

public void onStopTrackingTouch(SeekBar seekBar) {

// TODO Auto-generated method stub

if(mp!=null)

{

mp.seekTo(seekBar.getProgress());

mp.start();

}

}

@Override

public void onStartTrackingTouch(SeekBar seekBar) {

// TODO Auto-generated method stub

if(mp!=null)

{

mp.pause();

}

}

@Override

public void onProgressChanged(SeekBar seekBar, int progress,

boolean fromUser) {

// TODO Auto-generated method stub

}

});

}

Runnable run=new Runnable() {

@Override

public void run() {

// TODO Auto-generated method stub

SeekUpdation();

}

};

public void SeekUpdation() {

// TODO Auto-generated method stub

if(mp!=null)

{

int mpos = mp.getCurrentPosition();

int mdur= mp.getDuration();

sb.setProgress(mp.getCurrentPosition());

han.postDelayed(run, 1000);

tv1.setText(String.valueOf((float)mpos/100) + " s ");

tv2.setText(String.valueOf((float)mdur/100)+ "m");

}

}

}

Now media player is ready to test just your application on your virtual device or real device.
