public class WelcomeActivity extends Activity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_welcome);

        Timer timer=new Timer();
        TimerTask timerTask=new TimerTask() {
            @Override
            public void run() {
                Intent intent1=new Intent(WelcomeActivity.this,MainActivity.class);
                startActivity(intent1);
                WelcomeActivity.this.finish();
            }
        };
        timer.schedule(timerTask,1000*3);
    }
