Webview应始终返回null InterceptRequest方法

Webview shouldInterceptRequest方法始终返回null。我使用了adblocking方法。我尝试了许多adblock方法，但始终需要此shouldInterceptRequest方法，但其返回null

我的网络视图代码

webView.webViewClient = object : WebViewClient() {

        override fun shouldOverrideUrlLoading(view: WebView?, request: WebResourceRequest?): Boolean {




            view!!.loadUrl(request!!.url.toString())
            return true


        }

        override fun shouldInterceptRequest(view: WebView?, request: WebResourceRequest?): WebResourceResponse {
            return if (

                    AdBlocker.isAd(request!!.url.toString()))
                AdBlocker.createEmptyResource()
            else
                super.shouldInterceptRequest(view, request)
        }



        override fun onPageStarted(view: WebView?, url: String?, favicon: Bitmap?) {
            eTadres.setText(url)


            suankiurl= url!!
            super.onPageStarted(view, url, favicon)
        }



        override fun onLoadResource(view: WebView?, url: String?) {
            if (webView.visibility==View.GONE){webView.visibility=View.VISIBLE}
            super.onLoadResource(view, url)
        }


    }

super.shouldInterceptRequest（视图、请求）

将始终返回null（查看此代码的实现）。若你们想防止应用程序崩溃，你们应该使用下面的例子

更改为“：WebResourceResponse？”（“已添加”）

---

super.shouldInterceptRequest（view，request）

它应该返回null，检查您的

override fun shouldInterceptRequest的返回类型，根据文档，它应该可以为null：

包含响应信息的WebResourceResponse，如果WebView应该加载资源本身，则为null

override fun shouldInterceptRequest(view: WebView?, request: WebResourceRequest?): WebResourceResponse? {
            return super.shouldInterceptRequest(view, request)
        }
