Cross-platform Android Apps Development

The slide is here http://www.slideshare.net/khirulnizam/android-app-development-hybrid-approach-for-beginners

Yet another journey to mobile development using Apache Cordova (previously known as PhoneGap). Attended a course that introduce the usage of HTML5 and jQuery to develop a cross-platform mobile Apps.

STEP 1: Preparing the Apache Web Server

Download and install your preferred Apache web server. In my case, am using the Apache web server in XAMPP.

In your htdocs, create a folder for your project. Inside the project folder, create the items as shown in the picture below. An index.html, a js folder, css and image.

STEP 2: Copy the jQuery mobile templates

Available in the jQueryMobile - download the latest from here http://jquerymobile.com/resources/download/jquery.mobile-1.4.5.zip.

After finish downloading the jQuery for mobile installer, extract. Copy the CSS and JS library in the respective folder created in Step 1.

 

 

 

One HTML file can accommodate the whole apps – try this demo http://demos.jquerymobile.com/1.4.5/pages/

Now we code using NotePad++, create index.html on htdocs/mobile

 

<!DOCTYPE html> 
<html>
<head>
    <title>Page Title</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="css/jquery.mobile-1.4.5.min.css" />
    <script src="js/jquery-1.11.1.min.js"></script>
   1:  
   2:     <script src="js/jquery.mobile-1.4.5.min.js">
</script>
</head>

<body>
    <!-- Start of first page -->
    <div data-role="page" id="page1" >
        <div data-role="header" > Page 1 </div>
        <div role="main" class="ui-content"> Hi </div>
        <div data-role="footer"> kerul.net </div>
    </div>
    <!-- /end of 1st page -->
    <!-- Start of second page -->
    <div data-role="page" id="page2" >
        <div data-role="header" > Page 2 </div>
        <div role="main" class="ui-content"> Hoi </div>
        <div data-role="footer"> kerul.net </div>
    </div>
<!-- /end of 2nd page -->
</body>
</html>



Get Started! jQuery Mobile



jQuery Mobile

jQuery Mobile is a user interface framework based on jQuery that works across all popular phones, tablet, e-reader, and desktop platforms. Built with accessibility and universal access in mind, we follow progressive enhancement and responsive web design (RWD) principles. HTML5 Markup-driven configuration makes it easy to learn, but a powerful API makes it easy to deeply customize the library.

Packaging With Cordova


Preparing Android App For Google Play Using Windows



  • Requirement

  • Windows 7/8 in this case Windows 8
  • JAVA SDK
  • Android ADT
  • Apache ANT
  • NodeJS
  • Apache Cordova

For better understanding, create folder 'Mobile Dev' in Drive C.

All file will be downloaded here and this location 'C:\Mobile Dev' will be used for Apache ANT and Android Development Tool SDK.

We will go through STEP BY STEP with images to gain best understanding

Apache Cordova

Cordova is an open-source mobile development framework. It allows you to use standard web technologies such as HTML5, CSS3, and JavaScript for cross-platform development, avoiding each mobile platforms' native development language. Applications execute within wrappers targeted to each platform, and rely on standards-compliant API bindings to access each device's sensors, data, and network status

Android App

A mobile software application developed for use on devices powered by Google's Android platform. Android apps are available in the Google Play Store (formerly known as the Android Market), in the Amazon Appstore and on various Android App-focused sites, and the apps can run on Android smartphones, tablets, Google TV and other devices.

This tutorial is in the development process, sorry to keep you waiting.
