找不到文件上的WebView例外 - 當真正的文件存在

我想在網頁視圖加載網頁，但我得到以下異常：找不到文件上的WebView例外 - 當真正的文件存在

java.io.FileNotFoundException: https://fonts.googleapis.com/css?family=Roboto:400,300,500,700,900,700italic

但我驚訝的是，如果我點擊鏈接：

我可以在我的瀏覽器實際加載它。這也會發生在許多opther文件上，通常可以通過瀏覽器訪問。我在這裏錯過什麼？

下面是我的自定義實現：

WebViewClient webViewClient = new WebViewClient() { 

      @Override 
      public void onPageStarted(WebView view, String url, Bitmap favicon) { 
       startAnim(); 
       super.onPageStarted(view, url, favicon); 
      } 


      @Override 
      public void onPageFinished(WebView view, String url) { 
       super.onPageFinished(view, url); 
       if (webView.getProgress() == 100) { 
        stopAnim(); 
       } 
      } 


      @Override 
      public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { 
       NoNetworkDialog.showNetworkDialog(getActivity()); 

      } 

      @Override 
      public boolean shouldOverrideUrlLoading(WebView view, String url) { 
       if (!CheckConnection.isNetworkConnected(getActivity())) { 
        NoNetworkDialog.showNetworkDialog(getActivity()); 
        return false; 
       } else { 
        view.loadUrl(url); 
        return true; 
       } 

      } 

      @Override 
      public WebResourceResponse shouldInterceptRequest(WebView view, String url1) { 

       // if (!CheckConnection.isNetworkConnected(getActivity())) { 
       // NoNetworkDialog.showNetworkDialog(getActivity()); 
       // } else { 
       try { 
        URL url = new URL(url1); 

        HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection(); 


        CookieManager cookieManager = CookieManager.getInstance(); 
        String cookie = cookieManager.getCookie(url.getHost()); 


        urlConnection.setDoOutput(true); 
        urlConnection.setRequestProperty("Cookie", cookie); 
        urlConnection.setRequestProperty("***_USER_AGENT", "***_app"); 
        urlConnection.setRequestMethod("GET"); 

        InputStream in = new BufferedInputStream(urlConnection.getInputStream()); 

        return new WebResourceResponse(urlConnection.getContentType(), "UTF-8", in); 

       } catch (Exception e) { 
        e.printStackTrace(); 

        return null; 
       } 
       // } 
       // return null; 
      } 
     };
