- 6. PhoneGap Web App HTML5 JavaScript CSS Native APIs iOS Android Black Berry webOS etc... Wednesday, November 17, 2010
- 7. is Cross-Platform iOS, Android, BlackBerry 4.6+, webOS, Symbian... Open Source MIT outbound, MIT + Apache inbound Web Technologies defer to native support Spec-compliant where applicable, tracking DAP working group Extensible any native code available through plug-ins any JS libraries available through <script> Wednesday, November 17, 2010
- 8. Strictly Speaking PhoneGap: the native library • phonegap.jar, phonegaplib.a, etc • instantiates chromeless web view, loads www/index.html • adds JavaScript access to native APIs There are two parts to PhoneGap PhoneGap: the JavaScript files • phonegap.js • JavaScript wrappers for native API calls • is not required - your app can run natively as is Wednesday, November 17, 2010
- 9. For Designers • A PhoneGap app is bigger than a native app on a lot of platforms: • no location bar • no browser menu • There’s no browser chrome! • interactions should be explicit • It should have a launch screen • It should have some icons • Mobile app expectations != mobile web expectations Wednesday, November 17, 2010
- 10. For Developers • Write and test your JavaScript as normal • If you choose to use phonegap.js • listen for the deviceready event on the document object • then perform all PhoneGap-specific functionality • You should be able to avoid native code entirely • assuming nothing breaks • if you need extra plug-in functionality, bug us on the mailing list Wednesday, November 17, 2010
- 11. Native APIs • Device identification • Network access • Sensors • Geo, Accelerometer, Orientation, Magnetometer • Camera/image sources • Contacts • File access Wednesday, November 17, 2010
- 12. Generally Speaking • PhoneGap is • agnostic • permissive • relaxed • You don’t have to change the way you write apps Wednesday, November 17, 2010
- 13. Demo Time • A mobile web app, from Safari to native apps on • iPhone • Android • webOS Wednesday, November 17, 2010
- 14. Thick Clients remote APIs offline storage view templates Wednesday, November 17, 2010
- 15. If you put your web app in PhoneGap Then you won’t be able to rely on a web server So you will have do more on the client Wednesday, November 17, 2010
- 16. Remote APIs • Usually accessed on a server • due to the same-origin policy -- best you can do is JSONP • PhoneGap apps run on the file:// protocol • the file:// protocol is exempt from the same-origin policy* • XHRs can point anywhere • Simple as you like • $.get()... for example *well, unless it gets changed. But we’ll patch that if it happens Wednesday, November 17, 2010
- 17. Offline Storage • HTML5! • localStorage, sessionStorage, Webkit SQL, Google Gears, Indexed DB • Or native storage/external services • CouchDB! • Lots of libraries/wrappers • Ext.data.Store is the Sencha Touch class • we at Nitobi like Lawnchair Wednesday, November 17, 2010
- 18. View Templating • If your data’s local, then you’ll render your views locally • duh • Sencha does it! • Or use an opensource one; or roll your own; or whichever • My favorite is Mustache • Generally speaking, try to spend time working with Strings, as opposed to DOM elements • DOM manipulation is expensive Wednesday, November 17, 2010
- 19. Use Sencha Touch! You should’ve been at James’s talk Most of this stuff is taken care of: make sure you use it! Wednesday, November 17, 2010
- 20. Your server is there to store data persistently sync with new devices let you use the word “cloud” in your marketing Wednesday, November 17, 2010

- 22. PhoneGap Build Problem: Multiple SDKs to install, multiple operating systems to run them The crux of cross-platform pain. Solution: The cloud! Ahem. Online service for building and distributing PhoneGap apps Wednesday, November 17, 2010
- 23. PhoneGap Build Workflow • Develop HTML5 app locally: • index.html • icon.png • config.xml • Submit to PhoneGap Build • Upload • Hook into VCS (git, svn) • Download and Test App Binaries • Submit programmatically to App Stores Wednesday, November 17, 2010

- 28. PhoneGap Build Closed beta right now, supporting: Android, webOS, Symbian, BlackBerry Next couple of months • API access to allow IDE integration (Eclipse, Dreamweaver) • Support for iOS, WinPhone 7, Bada Further out • Plugin integration: build with arbitrary native code • testing/continuous integration Interested? Sign up for the beta (or harangue me) Wednesday, November 17, 2010
- 29. PhoneGap Dev Browser Problem: It takes too long to build apps, especially compared to web development. Who wants to wait for a compiler? Who wants to reset their device every time an app is updated?* Solution: A browser-style app that includes PhoneGap APIs. Put your PhoneGap app on a remote server, point the browser to it, test away. *BlackBerry owners Wednesday, November 17, 2010
- 30. PhoneGap Dev Browser Available on the Android Market now (free, naturally) Available on GitHub, more or less, for iOS who knows, it might get approved BlackBerry port in progress Wednesday, November 17, 2010
- 31. Sleight Problem: We can develop apps with the dev browsers, but none of our remote API calls work - because of the same origin policy. Solution: A node-js based web server. Serve static files from your disk, proxy remote resources from a target server. Wednesday, November 17, 2010
- 32. Sleight Setup: $ npm install sleight Usage: $ cd www $ sleight port=4000 target=api.twitter.com More details: https://github.com/alunny/sleight Wednesday, November 17, 2010
