        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.xnewsplashscreen);
        thread.start();          
    }
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_BACK) {
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }
   private Thread thread = new Thread()

    public void run()
    {

                    RunAnimations();
                    SystemClock.sleep(3000);
                    Intent iv = new Intent(NewSplashScreen.this,MainActivity.class);                  
                    startActivity(iv);
                    finish();

    private void RunAnimations() {
        Animation topout = AnimationUtils.loadAnimation(this, R.anim.animationtopout);
        LinearLayout ltop=(LinearLayout)findViewById(R.id.lyttop);
        ltop.startAnimation(topout);
     
        Animation bottoout = AnimationUtils.loadAnimation(this, R.anim.animationbottomout);
        LinearLayout lbottom=(LinearLayout)findViewById(R.id.lytbottom);
