在WebView android中缓慢加载URL

Question

我在应用程序中使用WebView加载网站。

在webview中加载我的网站的时间过长，但在Chrome浏览器应用程序中的速度非常快。

如何在WebView中加快时间加载网站？

我可以使用chrome而不是WebView android吗？或在WebView中使用chrome core？

我使用此代码但不起作用：

webView.setWebChromeClient(new WebChromeClient());

我的代码java webiew：

final WebView webView = (WebView) mRootView.findViewById(R.id.fragment_main_webview);

    // webview settings
    webView.getSettings().setBuiltInZoomControls(false);
    webView.getSettings().setSupportZoom(true);
    webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);

    webView.setBackgroundColor(getResources().getColor(R.color.global_bg_front));
    webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY); // fixes scrollbar on Froyo
    class MyJavaScriptInterface
    {
        @JavascriptInterface
        @SuppressWarnings("unused")
        public void processHTML(String html)
        {
            Log.e("classclass:",html);
            if (html.contains("class")){
                new Handler(Looper.getMainLooper()).post(new Runnable() {
                    @Override
                    public void run() {
                        webView.loadUrl(url2);
                    }
                });
            }else {
                new Handler(Looper.getMainLooper()).post(new Runnable() {
                    @Override
                    public void run() {
                        showContent();
                    }
                });
            }
        }
    }
    webView.addJavascriptInterface(new MyJavaScriptInterface(), "HTMLOUT");

    webView.setWebChromeClient(new WebChromeClient());
    webView.setWebViewClient(new WebViewClient()
