//avoid time consuming work in UI thread but if that is related to UI itself then do as below

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


            setContentView(R.layout.first_splash_lauoy);

            new Handler().postDelayed(new Runnable() {

                public void run() {
                  //Your time consuming work 
                  //with spiiner(if needed) & setContentView()
                  }, 1000);
        }

    }
