How to play, pause and stop the song in android?

I am making an app for Android and I have made three buttons to play, pause and stop.

My play and pause buttons are set up, so when I click the play button, it will become invisible and the pause button will display, and vice versa.

It works just fine when I click the play button, but after I click on the pause button, it gives me an error.

The code is given below.

 package com.mpIlango;

 import java.io.IOException;
 import java.util.ArrayList;
 import android.app.Activity;
 import android.media.MediaPlayer;
 import android.os.Bundle;
 import android.view.View;
 import android.widget.Button;
 import android.widget.RadioGroup;
 import android.widget.RadioGroup.OnCheckedChangeListener;

public class MpIlangoActivity extends Activity implements OnCheckedChangeListener {
/** Called when the activity is first created. */


MediaPlayer song1,song2,song3;
int whatsong = 0;

private ArrayList<Integer> songIds;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    RadioGroup rgMusic = (RadioGroup) findViewById(R.id.rgMusic);

    songIds = new ArrayList<Integer>();

    songIds.add(R.raw.fluet);
    songIds.add(R.raw.airtel);
    songIds.add(R.raw.titanic);


    final Button bPlay = (Button) findViewById(R.id.bPlay);
    final Button bStop = (Button) findViewById(R.id.bStop);
    final Button bPause = (Button) findViewById(R.id.bPause);

    bPause.setVisibility(View.GONE);

    rgMusic.setOnCheckedChangeListener(this);

    bPlay.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {           

             if(song1!=null)   {
                   song1.release();
                }

              if(song2!=null)  {
                   song2.release();
                }

              if(song3!=null)  {
                   song3.release();
                }

              switch (whatsong) {

                case 1:

                    try {

I guess you get a NullPointerException somewhere here!?

if(song1.isPlaying()){
    song1.pause();          
}

if(song2.isPlaying()){
    song2.pause();
}

if(song3.isPlaying()){
    song3.pause();
}

it that's the problem you may use your switch in here too.

switch (whatsong) {

    case 1: 
        if(song1.isPlaying()){
            song1.pause();          
        }

or initialize your songs somewhere else to make sure they will never be null

I also recommend using only one MediaPlayer.

MediaPlayer song;

bPlay code:

if(song!=null)   {
   song.release();
}

switch (whatsong) {

    case 1:

        try {
            song = MediaPlayer.create(MpIlangoActivity.this, songIds.get(0));
            song.prepare();
        } catch (IllegalStateException e) {                 
            e.printStackTrace();
        } catch (IOException e) {                   
            e.printStackTrace();
        }

}

song.start();
bPlay.setVisibility(View.GONE);
bPause.setVisibility(View.VISIBLE);

bPause code:

bPlay.setVisibility(View.VISIBLE);
bPause.setVisibility(View.GONE);

if(song != null && song.isPlaying()){
    song.pause();          
}

ALL of this Code is untested!
