First checkedbox: start app with splash screen and music ( achieved by below code ) ,

Second checkedbox: start app with splash screen and without music ( achieved by below code ) ,

Splash :

 public class Splash extends Activity{  
    MediaPlayer ourSong;
@Override
protected void onCreate(Bundle savedInstanceState) {
    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
         setContentView(R.layout.splash);  

    ourSong = MediaPlayer.create(Splash.this, R.raw.splashsound); 

    SharedPreferences getPrefs = PreferenceManager.getDefaultSharedPreferences

    boolean music = getPrefs.getBoolean("checkbox", true);
    if (music == true)      
    ourSong.start();

    Thread timer = new Thread(){
    public void run(){
        try{
            sleep(1000); }
          catch (InterruptedException e){
            e.printStackTrace(); }
          finally{
        Intent openMainActivity = new Intent("com.test.demo.MENU");
                startActivity(openMainActivity); }}

@Override
protected void onPause() {
            // TODO Auto-generated method stub
    super.onPause();
    ourSong.release();
    finish();
          }

    SharedPreferences getPrefs =PreferenceManager.getDefaultSharedPreferences(getBaseContext());
    boolean music = getPrefs.getBoolean("checkbox");
    if (music == true)  
    {
        setContentView(R.layout.splash);  
        ourSong = MediaPlayer.create(Splash.this, R.raw.splashsound);        
        ourSong.start();
        Thread timer = new Thread()
        {
            public void run()
            {
                try
                {
                    sleep(1000); 
                }
                catch (InterruptedException e)
                {
                    e.printStackTrace(); 
                }
                finally
                {
                    Intent openMainActivity = new Intent("com.test.demo.MENU");
                    startActivity(openMainActivity); 
                }
            }                          
        };
        timer.start();   
    }
