This document discusses web development, mobile applications, and cross-platform development. It defines web development as communication between a server and client using HTTP. It describes three types of mobile apps: native, web, and hybrid. Hybrid apps combine native and web technologies to leverage both web content and native capabilities. The document then discusses cross-platform development, which allows building apps that can be used on multiple mobile platforms using HTML, CSS, and JavaScript. It lists some popular cross-platform tools like Apache Cordova, PhoneGap, and Xamarin.

1. Hybrid App

2.  Web development is all about communication. In this
case, communication between two parties, over the
HTTP protocol:
 The Server - This party is responsible
for serving pages.
 Languages used: PHP, Python, ASP.Net in C#,C++ or
Visual Basic.
 The Client - This party requests pages from
the Server, and displays them to the user. In most
cases, the client is a web browser.
 The User - The user uses the Client in order to
surf the web, fill in forms, watch videos online,
etc.
Language used:JavaScript,HTML*,CSS*

3. • Mobile application divided into three categories: native
applications, mobile Web and Hybrid Web technologies.
•Native applications are specifically developed for one
platform hence takes full advantage of device
capabilities.
•Web apps are not exactly mobile apps but Web sites
that are mobile optimized.
•A hybrid application is a mix of both native and Web
technologies that are leveraged to deliver a mix of
Web content and native capabilities.
Mobile Application

4. Why use Mobile App?
Mobile Apps offer better personalization.
Ease of Sending Notifications.
Making Use of Mobile Device Features.
Can have ability to Work Offline
Freedom in designing.
New Branding Experiences
New Stream of Conversions
Apps can works Faster than Websites.

5. ANDRIOD apps
Codes are written
in java.
Jvm byte codes
are converted to
Dalvik byte codes.
Packaged with the
resource files.
Setup file
extension is .apk

6. Objective-C is used to develop ios apps.
Tools Required: Xcode
App extension is .ipa files
IOs apps

7. windows apps
Languages which can be used :
Visual C++, Visual C# and Visual
Basic, Client-side Jscript, ASP.NET
IDE : Visual Studio
File format/extension : XAP

10.  Cross-platform mobile development refers to the development of
mobile apps that can be used on multiple mobile platforms.
 Trend for BYOD is increasing.
 Development of corporate mobile apps and be able to send them
to many different mobile devices that operate on various networks
and use different operating systems.
 Uses CSS, HTML and JavaScript to develop the app that makes it
trendy.

11. TEN OF THE BEST MOBILE CROSS-
PLATFORM DEVELOPMENT TOOLS
 Xamarin
 PhoneGap
 Appcelerator
 iFactr
 Kony
 SAP
 Alpha Anywhere
 FeedHenry
 5APP

13. APACHE CORDOVA
 Apache Cordova is a platform for building natively
installed mobile applications using HTML, CSS
and JavaScript

14. HISTORY
 Apache Cordova was originally called Phonegap build by
Nitobi
 Open-source & free software from the beginning (MIT
License), Apache License now
 Nitobi then aquired by Adobe and donated the PhoneGap
codebase to the Apache Software Foundation (ASF)
 PhoneGap is still a product of Adobe. It is a distribution of
Apache Cordova.
Think of Apache Cordova as the engine that powers
PhoneGap.

15. CORDOVA ARCHITECTURE

16. APACHE CORDOVA
APPLICATION’S USER INTERFACE
 The user interface for Apache Cordova
applications is created using HTML, CSS, and
JavaScript.
 The UI layer is a web browser view that takes up
100% of the device width and 100% of the device
height.
 The web view used by application is the same
web view used by the native operating system
 iOS: Objective-C UIWebView class
 Android: android.webkit.WebView
 WP7: WebBrowser
 WP8: WebBrowser control (Internet Explorer 10)
 BlackBerry: WebWorks framework

17. APACHE CORDOVA API
 Provides an application programming interface (API)
 enables you to access native operating system functionality using
JavaScript.
 APIs for Accelerometer, Camera, Compass, Media, FileSystem, etc
 Extendable using native plug-in
Cordova Application
Cordova JavaScript API
and
Cordova Native Library Native API

18. DEVELOPMENT USING CORDOVA
 Tools for development
 Any text editor
 Platform SDK e.g. Android SDT, Android SDK, BB
SDK, Xcode, Visual Studio Community with
Cordova Tools.
 Platform Emulator (usually provide along with
SDK)
 JS/HTML GUI Mobile framework e.g. JQuery,
Sencha Touch, dojo Mobile
