I deployed my app and I got this issue.
The first time the app got loaded, it will show a blank white page for 5-7
second which is pretty long for a good user-experience. But after that, the
page show really really fast since it got cached.
The problem is that when i advertised my site in Adword. When many people
will visit my site for the first time, they could be impatient if it shows
a blank page for a long period time like that.
I think the solution is to make an loading indicator to indicate user that
the page is loading.
Actually I did do the indicator loading at the onModuleLoad method
public class MyProject implements EntryPoint {
private final ClientGinjector ginjector = GWT.create(ClientGinjector.class);
@Override
public void onModuleLoad() {
// This is required for Gwt-Platform proxy's generator
DelayedBindRegistry.bind(ginjector);
ginjector.getPlaceManager().revealCurrentPlace();
DOM.removeChild(RootPanel.getBodyElement(), DOM.getElementById("loading"));
}
}
In MyProject.html
<html>
<head>......</head>
<body>
<div id="loading">
Loading<BR/>
<img src="../images/loading.gif" />
</div>
<iframe.......></iframe>
......
</body>
</html>
However, the <div id="loading"> only works after all javascript files got
loaded. It doesn't work right at the beginning user visits the site & that
is why user will see a blank page for a pretty long time.
*I am not sure GWT app is good for advertising in Google*. But my page
passed the Ad review from Adword people, so it means the page must be
finally visible, otherwise Adword people will reject my page.
Can u figure out a solution for this?
