Head First

Android Development

Wouldn’t it be dreamy if

there was a book on Android

development that could turn me

into an expert while keeping me

engaged and entertained? But it’s

probably just a fantasy...

Jona than Simon

Before the modern smartphone era,

Jonathan Simon was coding away at the

cool phones of the day, writing low level UI

frameworks and debugging tiny screens (back

when 176x220 was huge!) with a magnifying

glass. Since then, he’s worked with all kinds

of phones, even the new ones with big fancy

schmancy screens.

Before working with mobile devices, Jonathan

spent a good six years working on Wall Street

designing and building user interfaces for

trading systems. And no, it’s not his fault the

stock market tanked, honest! He also can’t give

you any stock tips. (Sorry!)

When he’s not coding or designing, he’s

probably hanging out with his wife, Felisa,

or their dog, Billie. Otherwise, he’s probably

riding (or building) a bike or perfecting his

espresso extraction.

One of Jona than’s espresso

shots. It too k MANY of

these to wr ite this book.

Your First App

So you’re thinking: “What makes Android so special?

Android is a free and open operating system from Google that runs on all kinds

of devices from phones, to tablets and even televisions . That’s a ton of different

devices you can target with just one platform ! (And the market share is gaining

too!) Google provides all of the stuff you need to get started building Android apps

for free . You can build your Android apps on Macs, Windows, or Unix and publish

your apps for next to nothing (with no need for anyone’s approval). Ready to get

started? Great! You’re going to start building your first Android app, but first there

are a few things to set up...
