我有在 webview 上运行 jquery mobile 的网站。当活动开始时，一切正常，但在活动暂停 30 分钟或更长时间后，我返回 web 视图，它不再工作了。看起来 JavaScript 停止响应。

我正在使用 web.load(url) 方法加载网页。

@SuppressLint({ "NewApi", "SetJavaScriptEnabled" })
private void initUI(View view) 
{
    logger.info("initUI() - Initilazing Fragment UI");
    webViewPlaceholder = ((FrameLayout)view.findViewById(R.id.webViewPlaceholder));
    if (webView == null)
    {
        logger.info("initUI() - Creating WebView");
        webView = new WebView(this.getActivity());
        FrameLayout.LayoutParams layoutParameters = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,FrameLayout.LayoutParams.MATCH_PARENT);
        webView.setLayoutParams(layoutParameters);
        webView.addJavascriptInterface(new JavascriptUtils(this.getActivity()), "Android");
        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setAppCacheEnabled(false);
        webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
        webView.getSettings().setBuiltInZoomControls(true);
        webView.getSettings().setSupportZoom(true);
        if (Build.VERSION.SDK_INT >= 11){
             webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
        }
        webView.setHorizontalScrollBarEnabled(false);
        webView.setWebViewClient(SeeWhatYouLikeWebClientFactory.getWebClient(this));
        webView.setWebChromeClient(new SWYLWebChromeClient());
    }
    // Attach the WebView to its placeholder
    webViewPlaceholder.addView(webView);
}

谢谢
