ManifestR - offline web apps made easy (well easier) A Beginner's Guide to Using the Application Cache. Introduction It's becoming increasingly important for web-based applications to be accessible offline. Yes, all browsers can cache pages and resources for long periods if told to do so, but the browser can kick individual items out of the cache at any point to make room for other things. HTML5 addresses some of the annoyances of being offline with the ApplicationCache interface. Using the cache interface gives your application three advantages: Offline browsing - users can navigate your full site when they're offline Speed - resources come straight from disk, no trip to the network.
The Application Cache (or AppCache) allows a developer to specify which files the browser should cache and make available to offline users. The cache manifest file The cache manifest file is a simple text file that lists the resources the browser should cache for offline access. Referencing a manifest file To enable the application cache for an app, include the manifest attribute on the document's html tag:
Appcache Facts. 4 Tools for Building a Business Mobile App. In a world where there’s always “an app for that,” more small businesses see the value in creating their own mobile apps. The technical know-how necessary to develop an impressive app and the cost of hiring a professional developer, however, have discouraged the production of many would-be branded applications. Affordable do-it-yourself alternatives give all companies — even those with minimal tech expertise — a way to create their own apps.
Even the code-illiterate can build passable apps using these four new platforms. 1. Bizness Apps Bizness Apps focuses on industry-specific features. It's a difficult platform on which to customize beyond color choices, but it's a tool that's incredibly easy to use. Platforms: iPhone, iPad, Android, HTML5 Price: $39 per month for the iPhone app plus $10 per month for an iPad, Android or HTML5 app. 2. There's a better chance of creating and releasing a useful app with these features, but users also have a steeper learning curve than some of its competitors.
Creare un sito per iPhone con jQTouch e PHP | Beat Fly Blog | tutorial photoshop jquery css php. Ultimamente mi stò avvicinando molto al mondo del mobile con molto entusiasmo sia per la semplicità con cui possiamo sviluppare le nostre applicazioni, sia per la minore difficoltà che si può incontrare nell’utilizzo di TAG e scripts. Nel mio caso, possedendo da tempo un iPhone, ho scoperto come sia davvero divertente sperimentare mini siti o proporre applicazioni da vendere ai miei Clienti utilizzando ottimi strumenti open source disponibili in rete e continuando a mettere in pratica le normali nozioni CSS, JavaScript e PHP di sempre.
Non molto tempo fa, citai l’ottimo Framework jQTouch specifico per la creare applicazioni specifiche per iPhone i iPad e dunque proprio utilizzando lo stesso, vedremo oggi come creare da zero un sito ottimizzato per il device di casa Apple. Questo tutorial cercherà di spiegarvi come: Il sito che andrò a realizzare è composto di: Come si evince dal nome, jQTouch si appoggia al Framework jQuery, dunque iniziamo ad importare nella nostra pagina i file JS: How To Build A Mobile Website - Smashing Magazine. How to Build a Native Mobile Application in Dreamweaver CS5.5. In earlier articles we covered HTML5 Semantics and multiscreen authoring in Dreamweaver. In this article we're going to look at the process of building a native phone application in Dreamweaver CS5.5. The PhoneGap framework has become popular with web designers who want to write native moble applications using HTML, JavaScript and CSS.
Adobe decided to team up with these people and integrate their framework for Android and iOS directly into Dreamweaver. Having said that, it's necessary to install the Android and iOS SDK's into Dreamweaver in order to be able to use them. Note that for the PC, you can only install the Android SDK, on the Mac platform, you can install both. The Android SDK is meant to install seamlessly with a one-touch button. Not wanting to give up, I conducted another search and found this document: Error "Android SDK failed to install" with Easy Install | Dreamweaver CS5.5. Note: This problem appears to be with the Android emulator and doesn't appear to be with Adobe. Building Mobile JavaScript WebApps With Backbone.js & jQuery: Part I. Building a Mobile Web Application with the Google Reader API. Full Screen Web Apps. One of the first problems encountered when building a mobile web app from scratch is the amount of space consumed by the browser's address bar.
This tutorial will demonstrate how to reclaim the screen real estate otherwise lost to the address bar while accounting for orientation changes, content height problems, and internal document links. Subsequent Changes to Techniques & Software Certain aspects of applications or techniques used in this tutorial have changed since it was originally published. This might make it a little difficult to follow along. We'd recommend looking at these more recent tutorials on the same topic: Mobiletuts+ Web Apps Category Defining the Problem One of the most difficult aspects of designing for mobile devices is the limited amount of screen space available. For example, consider the following mobile web site screen shot: The above screenshot was taken on an iPhone 4 with both the Mobile Safari address bar and toolbar displayed. The Meta Tag Approach Event listener: Create Your Own Fullscreen Web Apps With Fullscreen.me. Fullscreen.me is an interesting service that allows you to create iOS web apps that run in fullscreen mode.
You can create little web apps through mobile Safari using Fullscreen.me’s website interface. This is nice if you have a lot of websites that you visit on your iPhone, and you don’t want to have to navigate through Safari tabs to try to view them all. You can instead create little icons on your home screen of all your favorite sites… If you visit Fullscreen.me on your iPhone, you are given the option to enter a URL to create a fullscreen web app. There is also a nice list of popular iOS compatible websites to choose from (all Google apps). It’s nice to be able to run these optimized interfaces like a real app in fullscreen mode.
If there’s another site that you want to create a fullscreen app of, you simply have to enter the desired URL to Fullscreen.me. I tried the process with apple.com. Fullscreen.me is great for creating customized web app experiences on your iPhone. jQuery e CSS3, lavorare con le Media Queries. Nella scorsa uscita Sviluppare layout con le Media Queries abbiamo realizzato un layout, "one page site", con HTML5 e i CSS3 con un'interfaccia dinamica che si adatta al dispositivo di navigazione utilizzato, sia esso uno smartphone, un tablet o un normale computer. Nella seconda parte ora, applicheremo a questa struttura di base alcune tecniche per migliorarne la user experience, facendo ricorso a Javascript e al supporto del framework jQuery. Tutto il codice presentato va naturalmente richiamato all'interno del metodo $(document).ready, in modo da essere eseguito non appena è disponibile l'albero DOM del documento.
A prescindere dal device, la pagina di esempio presenta un andamento di navigazione verticale e può essere utile gestire, con uno script, lo scroll tra i link interni e le loro destinazioni, ottenendo un piacevole effetto.

One of the several features outlined in the HTML 5 specification is the support for Web applications that continue to work while they are offline. This feature is very useful for Web applications because a Web application can be loaded just once and then run offline without needing a persistent Internet connection, making it behave just like a locally installed native application.
Dashcode supports the manifest attribute available in the HTML 5 specifications for offline web applications. And so in this article, you will learn how to write offline iPhone Web applications using Dashcode. Enabling Offline Mode To enable your iPhone Web applications to run in offline mode, you first need to configure your project in Dashcode. Using Dashcode, create a new Custom project, save it and name it as OfflineApp. Click on the Application Attributes tab and check the “Allow offline viewing of this web application” option (see Figure 1).
Figure 1.Enabling your application to run in offline mode Figure 2. Get off(line) Taking your web sites and apps offline with the HTML5 appcache There’s a general (and understandable) belief by even many developers that web sites and web applications can only be used when the browser has a web connection. Indeed, this is routinely cited as one of the real advantages of “native” apps over web apps. But as unintuitive as it sounds, in almost every modern browser and device (except even for now IE10 developer previews, but here’s hoping that changes), that’s not the case, provided the developer does a little extra work to make their app or site persist when a browser is offline. (Of course the user must have visited your site while their browser did have a connection) In this article, I hope to clear this whole areas up once and for all, show you how to do it, and point to some great resources out there for learning more about creating offline versions of your web sites and apps.
Making a cache Making it manifest An appcache manifest Here is a very straightforward example.
