What is PhoneGap?

PhoneGap Pattern1. Embed a chromeless browser in a native app2. Create a “bridge” between the browser and the native code3. Write a web app!

Write once debug everywhere

How do you write PhoneGap apps?

Mobile web ﬁrst!• Basics.• Tooling.• Libraries.

Basics: HTML<button>I’m native codes!</button>

Setup the Viewport<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no;" />

Basics: CSS3• Media queries come in handy for tablets• Many folk using precompilers these days• Opacity, rounded corners, gradients and fucking drop shadows fuck ya!

CSS3 Animations-webkit-transform: translate3d(x,y,z) scale3D(1,1,1.0)

Media Query

Media Query<link rel="stylesheet" media="all and (max-device-width: 480px)" href="iphone.css">

Media Query<link rel="stylesheet" media="all and (max-device-width: 480px)" href="iphone.css"><link rel="stylesheet" media="all and (min-device-width: 481px) and (max-device-width: 1024px) and(orientation:portrait)" href="ipad-portrait.css">

Media Query<link rel="stylesheet" media="all and (max-device-width: 480px)" href="iphone.css"><link rel="stylesheet" media="all and (min-device-width: 481px) and (max-device-width: 1024px) and(orientation:portrait)" href="ipad-portrait.css"><link rel="stylesheet" media="all and (min-device-width: 481px) and (max-device-width: 1024px) and(orientation:landscape)" href="ipad-landscape.css">

Basics: JavaScript• Language of the web.• Scheme with a C syntax.• Some quirks: http://wtfjs.com

Startupdocument.addEventListener( ‘deviceready’, function() { alert(‘WINNING!’); }, false);

Performance• Use those CSS transforms!• Don’t set style properties inside a loop!• Don’t do what you do on the web!

Basics: conﬁg.xml• Lifted from the W3C Widget Spec• Many variants. See rubygem ‘confetti’• Handy for packaging metadata.• Wtf is packaging metadata?

conﬁg.xml example

<!DOCTYPE html><html> <head> <title>Vanilla</title> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no;" /> <link rel="stylesheet" href="css/app.css" type="text/css"media="screen"> </head><body> <h1>Vanilla!</h1> <p>Ice Ice Baby</p> <script src="phonegap-0.9.4.js"></script> <script>document.addEventListener(‘deviceready’, function(){}, false); </script></body></html>

Will PhoneGap work on my Chumby?

Can you put PhoneGap apps in the App Store /Android Market / whatever?

Who dreamed up the PhoneGap APIs?

PhoneGap APIs• Sensors• Data• Events http://docs.phonegap.com

Sensors• GPS• Accelerometer• Compass• Network• Camera

Data• Contacts• Media• File system• Notiﬁcations

Events• onload (duh)• ondeviceready (this is special)• onnativeready• onresume• onpause

W3C• dev.w3.org/geo • geolocation + deviceorientation + devicemotion• dev.w3.org/dap (device apis and policy) • contacts, calendar, HTML media capture, Media capture api, Messaging, System info• webapi • Web notiﬁcations

HTML5• <canvas> • Cache manifest• <audio> • postMessage• <video> • Web SQL• Drag and drop • localStorage• File API • Sockets• History API • Workershttp://dev.w3.org/html5/spec/Overview.html

API “design”The “standards” are a mess.Quotes here are not ironic.

Browser APIs...

Or maybe like this?

Browser Persistence APIs• SQLite has been a complete fuck up.

WAC• formerly JIL and BONDI• a carrier consortium

Browser Media APIs• Lets not even go here..• Audio and video are horribly fucked up• ESPECIALLY on mobile• We ﬁx ‘em (attempt to) w/ PhoneGap tho!

DAP Media Capture

Web-ish SDKs Trending.. • Symbian WRT • HP Palm webOS • BlackBerry WebWorks • Samsung Bada * PhoneGap started in 2008 btw...

Everyone Differentiates And their target abstraction is JavaScript?

We will too ...

How do I extend PhoneGap?

Plugins to the rescueClean from an engineering perspective.Lighter builds possible.Adaptable for 3rd party extensions.Portable to new platforms.Secure only use what you need.Override anything with JS or Native code.

Remaining work• Discovery• Packaging / installation• Identity / trust

PhoneGap Plugins 1.0CoreMaintained by us.CommunityWild west!PartnerMaintained by you; veriﬁed by us. =)

Plugins • Push notiﬁcations • Ads • Analytics • Barcode scanning • Facebook Connecthttp://github.com/phonegap/phonegap-plugins

What tooling is available?

Compilers / Miniﬁers• YUICompressor• Google Closure• UglyfyJS

IDES• Textmate (PhoneGap bundle)• Eclipse (AppLaud plugin for Android)• Dreamweaver (CS 5.5)

Emulators• Every SDK has one. Most of them suck.• ios-sim• Ripple• WebKit, eh

Debuggers• WebKit nightly is your friend. Mine too.• Weinre

HTML5 Debugging• console.log is supported btw• so is alert ...

What libraries are available?

Web VS Native? http://www.ﬂickr.com/photos/40336611@N08/3705419486/sizes/z/

The Web is Native

“We could probably save 70% of ourdevelopment budget by switching to a single, cross-platform client, but wewould probably lose 80% of our users.” -- Phil Libin, Evernote CEO

“97.25% of statistics are wrong” -- Anonymous

“we’d be shut out of most app stores and go back toworrying about distribution.” -- Phil Libin again

“huh?” -- Me

Can you put PhoneGap apps in the App Store /Android Market / whatever?

$12,000,000,000

What would Reed say?

“Are you fucking crazy!?!?!”-- Maybe Reed Hastings, Netﬂix CEO would say this

Why are they using it?

Skills reuse

Time to market

Less code

App updates

A/B Testing

Building for hundreds of devices!!1!1http://functionsource.com/post/netﬂix-feature

No shit.

Can the Web feel Native?

“What you call love was invented by guyslike me to sell nylons” -- Don Draper, Mad Men

“Be the needlenot the haystack” -- Don Draper, Mad Men

Games?

Need more examples?
