My experience is that loading websites in a WebView is much slower than performing the same actions in the Android Web Browser. I can see that all files have been loaded in

    I finally got the reason of android webview bad performance issue. Notice the image below... It used 12 seconds from OnPageStarted to OnPageFinished. Because it should load CSS,javascript and ... AJAX...

    the debug window:

    I notice that JQuery and JQueryMobile need load all DOM struct in Html.So if I lazy load the javascript after OnPageFinished,it should show page faster.

    First use setTimeout instead of $(document).ready(function() {}); in JQuery.Then use lazyload javascript file.

    The final html and javascript is:

    
    
            
    

    You can find lazyload-min.js in http://wonko.com/post/painless_javascript_lazy_loading_with_lazyload

    After do that,you can see the log image below:

    after change the javascript

    Now, it only takes 2 seconds from OnPageStarted to OnPageFinished.

    I posted the article at https://wenzhang.baidu.com/page/view?key=22fe27eabff3251f-1426227431

    But it was written in Chinese:)
