我试图创建这个android应用程序我有这个使用说明或覆盖一个不推荐的api我怎么能修复它？？代码如下：

public class SplachScreen extends AppCompatActivity {

public static int Splash_time = 2000;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splach_screen);

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {

            Intent intent = new Intent(SplachScreen.this, MainActivity.class);
            startActivity(intent);
        }
    }, Splash_time);

  }
}
