Mobile Implications Apps must be written for different

devices

Web pages need to be designed for smaller screens

Apps must be very efficient and small

Apps distributed through “stores” Some stores have many hurdles for

developers

Why Bother Enable customer access

anytime anywhere

Increase field employees productivity

Real time data exchange from mobile devices

Track location of delivery truck and reroute based on traffic info

Why Android? Did I mention 700,000 new

devices a day? (Google est.)

Open source (aka Free)

Android Market not as restrictive as some other stores

Android Concepts▀ Screens/windows defined with

XML and are comprised of views

A button, label, text field, etc. are considered views

▀ Applications comprised of activities

Activities can display and retrieve screens/windows and their components

Android Concepts▀ Eclipse with Android plug in most

popular IDE

Lots of tools: emulator, syntax checker, logcat

►However Google recently released their IDE - Android Studio

▀ Initially creates a very specific structure for applications

Not very java-novice friendly

Will ignore in the beginning
