问题 I am creating a HTML5 web app for mobile devices and was asked to hide the browser nav bar (the back & forward buttons) (typo here prev.). How can I achieve that? I think I should be able to achieve that using Phone Gap. But I wonder if its possible for a "normal" web app to hide the browser bar? I think its possible if I pin the web site/app to the home screen? iPhone has http://ajaxian.com/archives/iphone-full-screen-webapps, but what about Andriod at least? 回答1: I know this question is a

问题 My native iphone app, developed with phonegap with jquery (so its browser based), can log in to web server and once logged in users can access their resources. The server sets session id in cookie once user is authenticated.

问题 So I've only seen one website do this and I'm very curious to know how they do it. I'm using an iPhone 4 with iOS5 by the way.

The mobile site shows up without any of the Safari buttons or address bar. It even shows up in the open app tray as an open stand-alone app (double-tab the home button to see what I mean when Funny or

问题 Does anyone know of a way in which you can deploy a WebGL app as a native iOS or Android app? Commercial middleware is acceptable, although an open project would be preferable. Thanks. 回答1: As an extension to Joris' answer (which appears to be based on the work of Nathan de Vries), the following is the code I needed to enable WebGL within the iOS 5.0 SDK: Somewhere near the top of your view controller implementation: @interface UIWebView() - (void)_setWebGLEnabled:(BOOL)newValue; @end

问题 I'm creating and android game powered by andengine framework the box2d extension I'm getting "Fatal Signal 11" which seems to happen out of nowhere (I guess you can call it randomly) there no clues (at least, I don't aware to any clues to help me solve this problem) my guesses are: 1) I'm creating game's entities using TimerTask class 2) maybe it has something to do with concurrency? what do you think? thanks, socksocket 回答1: You could still use a TimerTask, you just need to be sure to call
