Splash screen

Splash screen will appear for about 3 seconds when the application is starting up

public class SplashScreen extends AppCompatActivity {
    private final int SPLASH_DISPLAY_LENGTH = 3000;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        //2 lines of code make app fullscreen
        setContentView(R.layout.activity_splash_screen);

        new Handler().postDelayed(new Runnable(){
            @Override
            public void run() {
                /* Create an Intent that will start the Menu-Activity. */
                Intent i = new Intent(SplashScreen.this, MainActivity.class);
                startActivity(i);
            }
        }, SPLASH_DISPLAY_LENGTH);
