PhoneGap
Now and the Future
What is PhoneGap?
A way to build cross platform native applications using web technologies
What is PhoneGap?
1) Write a web app using HTML5 technologiesJS/HTML/CSS
What is PhoneGap?
2) Package your web app into PhoneGapCommon device interface: PhoneGap API
Extend: PhoneGap PlugIns
What is PhoneGap?
3) Deploy to multiple devicesiOS, Android, Blackberry, WP7, WebOS, …
What is PhoneGap?PhoneGap API:• An interface to the most common set of
device functionality
• Contacts, GeoLocation, File, Camera, etc…
• All accessible through JS
• docs.phonegap.com
What is PhoneGap?PhoneGap API:
Geolocation:
var win = function(position) { console.log(position.coords) }, fail = console.log(‘I failed’);
navigator.geolocation.getCurrentPostion(win, fail)
What is PhoneGap?PhoneGap API:
Vibration:
navigator.vibrate(1000)
navigator.vibrate([1000])
navigator.vibrate([1000, 500, 2000])
What is PhoneGap?PhoneGap API:
App life cycle events:document.addEventListener('deviceready', appInit, false) document.addEventListener('pause', appPause, false) document.addEventListener('resume', appResume, false)
var appInit = function() { alert('app initd') }
var appPause = function() { alert('paused') }
var appResume = function() { alert('resume') }
What is PhoneGap?PhoneGap PlugIns:• A way to extend your PhoneGap app if you want
to access more than what the PhoneGap API provides
• Process: Write a native implementation then use JS to call that native function (Cordova JS!)
• Currently a work in progress but check out https://github.com/phonegap/phonegap-
plugins
What is PhoneGap?PhoneGap PlugIns:
Some examples:• Child Browser• In App Purchasing• Barcode scanner• Twitter
Why PhoneGap?
Why PhoneGap?• Need a dev who knows the platform
• Multiple code bases
• Longer turn around time to get releases out to all platforms
Why PhoneGap?
Write Once Debug Everywhere
Why PhoneGap?
PhoneGap Build
Why PhoneGap?• Upload your app to PhoneGap
then build and compile in the cloud
• No need to download sdks
• Free open beta right nowbuild.phonegap.com
Who Makes PhoneGap?
• Nitobi/Adobe• IBM, RIM, Microsoft• Various individual contributors• Apache
How to Use PhoneGap
• Demo
Where Are We Going?• PhoneGap donated to the apache
foundation!
• Now exists under the name Cordova
• Contribute back today: incubator.apache.org/cordova/
Where Are We Going?
The Adobe years:
The original creators of PG – Nitobi aquired by Adobe• No more client work! Full time work on PhoneGap
Integration with other Adobe products• DreamWeaver• And more…
Where Are We Going?
• Apache Licensed – free and open source
• Our device api specs follow wc3 standards
• If browsers ever decide to implement the wc3 specs, then your app is future proofed
Where Are We Going?
• Cordova JS/Unified JS:• Fragmentation started to creep into PhoneGap.js
as more platforms added
• Now we use a modular syntax to define PG components
• Everything is a plugin now
Where Are We Going?
• Cordova JS/Unified JS:Easy to add new platforms or extend an existing platform
Wishing for installable, discoverable, removable plugins• Similar to NPM • Command line tooling soon!
Where Are We Going?
Concerns:• Security• Privacy• Permissions• Capabilities• Performance
Where Are We Going?
More device support:• Ios• Android• BlackBerry 5+• webOS• WP7• Bada• …What’s next?
Thank you!
