Webview在更新Chrome 76后顯示空白頁

Question

我正在使用WebView來顯示信息的項目上，我應該使用shouldInterceptRequest添加標頭。 一切正常，但是更新chrome 76之后，它顯示空白頁，僅應調用了InterceptRequest。

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);

我曾嘗試一些解決方案： 這個 ， 這個 ，但沒有工作。 我該如何解決？

我也面臨這個問題。 發生這種情況是因為您已啟用dom存儲。.從chrome清除緩存並清除應用數據，卸載並再次運行。.在我看來，它是一種魅力。.希望它在您的情況下也能使用
