UniPlugin-Hello-AS 项目中 uni-app 我想自定义splash activity 但是怎么也越过不了自带的启动页

测试过的手机：

hormonyos 4.2.0

示例代码：

public class SplashActivity extends AppCompatActivity {  
    private WebView webView;  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        EdgeToEdge.enable(this);  
        setContentView(R.layout.activity_splash);  
        new Handler().postDelayed(new Runnable() {  
            @Override  
            public void run() {  
                FilePicker.sendMessageToUniApp("dsadsah");  

                Intent intent = new Intent(SplashActivity.this, PandoraEntry.class); // 替换为你的主Activity类名  
                startActivity(intent);  

                finish(); // 关闭SplashActivity  
            }  
        }, 1000); // 延迟3秒跳转，单位是毫秒  
    }
}
