Webview在更新Chrome 76后显示空白页

Question

I'm working on a project which use a WebView to show information, I used shouldInterceptRequest to add headers. Everything was working normally But after I updated chrome 76, It show blank page, and only shouldInterceptRequest was called.

webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setDomStorageEnabled(true);
    webView.getSettings().setLoadWithOverviewMode(false);
    webView.getSettings().setAllowFileAccess(true);
    webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    webView.getSettings().setSupportMultipleWindows(true);
    webView.getSettings().setPluginState(WebSettings.PluginState.ON);
    webView.clearCache(true);
    webView.getSettings().setAppCacheEnabled(false);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        webView.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
    }
    webView.setWebViewClient(new WebViewClient() {

        @TargetApi(Build.VERSION_CODES.LOLLIPOP)
        @Nullable
        @Override
        public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
            Log.d("TAG", "shouldInterceptRequest: 2");
            if (!checkFirstLoad) {
                try {
                    checkFirstLoad = true;
                    Request req;
                    OkHttpClient httpClient = new OkHttpClient();
                    req = new Request.Builder()
                            .url(PA_URL.trim())
                            .addHeader("Pa-Token", token)
                            .addHeader("Pa-Redirect", url)
                            .addHeader("Pa-App-Token", randomString())
                            .addHeader("Pa-App-Encrypt", md5(deviceId+oldToken)).build();

                    Response response = httpClient.newCall(req).execute();
                    return new WebResourceResponse(MimeTypeMap.getFileExtensionFromUrl(request.getUrl().toString()),
                            response.header("content-encoding", "utf-8"),
                            response.body().byteStream());
                } catch (IOException e) {
                    e.printStackTrace();
                    return null;
                }
            } else {
                return null;
            }
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            Log.d("TAG", "shouldOverrideUrlLoading: "+url);
            return true;
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
            view.loadUrl(request.getUrl().toString());
            Log.d("TAG", "shouldOverrideUrlLoading: "+request.getUrl().toString());
            return true;
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            progressBar.setVisibility(View.VISIBLE);
            Log.d("TAG", "onPageStarted: "+url);
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            progressBar.setVisibility(View.GONE);
            Log.d("TAG", "onPageFinished: "+url);
        }

        @Override
        public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
            super.onReceivedSslError(view, handler, error);
            handler.proceed();
            Log.d("TAG", "onReceivedError: "+error);
        }

        @Override
        public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
            super.onReceivedError(view, request, error);
            progressBar.setVisibility(View.GONE);
            Log.d("TAG", "onReceivedError: "+error);
        }

        @Override
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            super.onReceivedError(view, errorCode, description, failingUrl);
            progressBar.setVisibility(View.GONE);
            Log.d("TAG", "onReceivedError: "+ description);
        }
    });

    webView.loadUrl(url);

I had tried some solutions : this , this but not working. How can I solve this?

I have also face this problem. This occurs because of you have enabled dom storage.. Clear cache from chrome and clear app data, uninstall and again run.. It works in my case as a charm.. Hopefully it will also work in your case
