Application Craft is one of the sophisticated cross-platform tool used to build Web App + PhoneGap combined apps for smart devices. The Application Craft is web app which runs in cross -platform(windows,Linux, Mac OS X) compatible with Chrome, Safari, Firefox. To start building apps with Application Craft , lets first sign up @ http://www.applicationcraft.com/

Lets create Mobile App from your developer site & start building apps. You have option either to design & code & put the PhoneGap controls.

  • Keep controls drag & drop & build apps for cross-platform mobile tools.

A Sample of Mobile Web 2.0 with HTML5 Boilerplate, CSS3 Media Query, JQuery Mobile,Mobile Ajax/Dojo.


Mobile 2.0 is impossible to think without JQuery Mobile/JQTouch/Sencha/Mobile Ajax with cross-platform tools support like Phonegap, RhoMobile or Titanium  or Monotouch.

HTML 5 LocalStorage Mobile Web Application with PhoneGap for Windows Phone 7& i-Os


One of the great feature of HTML 5 is the support of localstorage & sessionstorage which is also redefined in Windows Phone as Isolated Storage. Building Offline Application Cache with manifest  files thus becomes easy for web apps of smartphones.

This article demonstrates how to use localstorage functionality in HTML 5 with PhoneGap support. For this rendering just creating a Mobile JQuery Project from Visual Studio template as like this:

  • Next some HTML 5 Code in Index.aspx as basic CSS 3 styles & JavaScript rendering.

<%

@Page Language=”C#”AutoEventWireup=”true”CodeBehind=”Index.aspx.cs”Inherits=”MobileWeb_App.Index” %>

<!DOCTYPE htmlPUBLIC“-//W3C//DTD XHTML 1.0 Transitional//EN”http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”&gt;

<html xmlns=”http://www.w3.org/1999/xhtml”&gt;

<head runat=”server”>

<title>Mobile Web without Server</title>

<script>

document.addEventListener(“DOMContentLoaded”, function () {

var foodList = document.getElementById(‘foodList’);

var foodField = document.getElementById(‘foodName’);

document.getElementById(‘foodForm’).addEventListener(‘submit’, function (evt) {

evt.preventDefault();

var newFood = foodField.value;

var newFoodItem = document.createElement(‘li’);

newFoodItem.innerHTML = newFood;

foodList.appendChild(newFoodItem);

foodField.value =“”;

return false;

},

false);

});

</script>

<style>

 body

{

background:white;

}

div#main

{

background:#ccc;

border:black1pxsolid;

height: 82%;

padding:10%;

width:80%;

-webkit-border-radius:8px;

}

</style>

<meta name=”viewport”content=”width=device-width,initial scale=”1.0/>

</head>

<body>

<div id=”main”>

<h1>List Some Food</h1>

<form id=”foodForm”>

<input type=”text”id=”foodName”placeholder=”A name of Food”/>

<button id=”submitFood”>Tell Us</button><br/>

<ul id=”foodList”>

</ul>

</form>

</div>

</body>

</html>

  • Lets look in iPhone 4 Mobile Safari.

  • Lets add some code for localstorage in HTML 5 which will be stored as browser offline cache.

var  l = window.localStorage.length;

var i = 0;

var storedFoodName;

function addNewFoodItem(foodName) {

var newFoodItem = document.createElement(‘li’);

newFoodItem.innerHTML = foodName;

foodList.appendChild(newFoodItem);

}

for (i; i < 1; i++) {

storedFoodName = window.localStorage.key(i);

if (storedFoodName.match(/^food[.]/))

addNewFoodItem(window.localStorage.getItem(storedFoodName))

}

  •  Lets have output for Windows Phone 7 & HTML 5 supported Internet Explorer 9 with GPU acceleration.

  • Internet Explorer 9 renders like this:
