Answer 1

Why not get the html first then pass it to the web view?

private String getHtml(String url){
    HttpGet pageGet = new HttpGet(url);

    ResponseHandler handler = new ResponseHandler() {
        public String handleResponse(HttpResponse response) throws ClientProtocolException, IOException {
            HttpEntity entity = response.getEntity();
            String html; 

            if (entity != null) {
                html = EntityUtils.toString(entity);
                return html;
            } else {
                return null;
            }
        }
    };

    pageHTML = null;
    try {
        while (pageHTML==null){
            pageHTML = client.execute(pageGet, handler);
        }
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return pageHTML;
}

@Override
public void customizeWebView(final ServiceCommunicableActivity activity, final WebView webview, final SearchResult mRom) {
    mRom.setFileSize(getFileSize(mRom.getURLSuffix()));
    webview.getSettings().setJavaScriptEnabled(true);
    WebViewClient anchorWebViewClient = new WebViewClient()
    {

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

            //Do what you want to with the html
            String html = getHTML(url);

            if( html!=null && !url.equals(lastLoadedURL)){
                lastLoadedURL = url;
                webview.loadDataWithBaseURL(url, html, null, "utf-8", url);
            }
}

This should roughly do what you want to do. It is adapted from Is it possible to get the HTML code from WebView and shout out to https://stackoverflow.com/users/325081/aymon-fournier for his answer.
