Hybrid Approach

Hybrid Approach – consists
of
 HTML + jQuery (JavaScript, CSS)
 Apache Cordova (HTML to Android
Project)
 Eclipse ADT – to generate APK
 Xcode – to generate iOS app

What are tools needed to
develop Android App Hybrid?
 HTML knowledge
 jQuery (JavaScript + CSS framework)
 Apache Cordova
 NodeJS
 Apache Ant
 Latest JDK
 Eclipse ADT Bundle
 Android SDK (for Android app)
 Xcode (for iOS app)

Apache Cordova
 Previously known as PhoneGap
 use HTML5 and CSS3 for interface
rendering, and JavaScript for logic
 HTML5 provides better support for GPS,
camera, video, etc.
 includes basic plugins that allow access to
the device's hardware’s.
 embeds HTML5 code inside a native
WebView on the device, using a foreign
function interface to access the native
resources of the device.

CSS | HTML
JavaScript

Apache ANT
 Apache Ant is a Java library and
command-line tool
 to drive processes described in build
files as targets and extension points
dependent upon each other.
 The main known usage of Ant is the
build of Java applications.

NodeJS
 Node.js contains a built-in library to
allow applications to act as a Web
server without software such as Apache
HTTP

Where to distribute my
App?
 Play.google.com
 Apple App Store
