This document summarizes a presentation on developing mobile apps for WebKit browsers using XPages. The presentation covers using Dojo to give mobile apps a native look and feel on different platforms. It demonstrates accessing native device services through PhoneGap and caching data to support offline use. It also shows various reusable controls that have been developed for mobile apps using frameworks like Dojo, Wink toolkit, and cubiq.org. The presentation concludes with discussing upcoming features in Dojo that could improve mobile development and evaluating providing the controls as out-of-the-box XPages controls.

5. Goals of the OpenNTF Project
● Identify which out of the box app dev functionality for mobile apps IBM®
Lotus® Domino® could support in future releases
● Demonstrate how to use the Lotus Domino XPages app dev platform today to
build mobile apps with standard web development skills without having to
write native/device specific code
● Demonstrate how to build mobile apps for Android™, iPhone® and
Blackberry® using XPages

6. Technical Goals
● Enable developers to develop mobile apps via XPages (rapid application
development, access to Lotus Domino services, etc.)
● Enable developers to build mobile apps that look & feel like native apps to
achieve the best user experience
● Enable developers to build sophisticated mobiles apps accessing native
services and supporting offline
● Enable developers to build mobile apps via XPages easily, e.g. via reusable
controls

8. Native Look & Feel
● Many iPhone apps use the typical iPhone style
● Android has it's own style but few apps use it
● Blackberry doesn't seem to have it's own style
● Not all apps use these styles, but many of the most popular apps, esp. for
iPhone
● Most Android and iPhone apps use nice page transitions
● This is not only nice to have, but required to get the necessary user
acceptance. Mobile users have high expectations since they know it from
other apps
● Technically this means one HTML/XSP page with lot's of hide/show and Ajax

11. OpenNTF Project uses Dojo
● Dojo 1.5 (dojox/mobile) provides a framework to build web apps that look and
feel like native apps
─ Page transitions
─ Loading indications
─ Typical styles for iPhone and Android
● The project leverages Dojo 1.5
● Custom styles can be used
● Reusable controls are provided to assemble custom apps
● A live version of this app is available under http://i.openntf.org

12. Loading of new Content
● View control loads new
entries automatically when
scrolling down
● Progress indicators for view
and document loading

13. Creation of new Documents
● Project shows how to create new
documents (via Ajax)

14. Bookmarks
● Pages including pages with documents
can be bookmarked
─ e.g. http://i.openntf.org/niklas/

15. Navigation
● Browser and device navigation buttons are
supported

16. Sticky Scrollbars
● W hen navigating back to the view the scrollbars are sticky

18. Reusable Controls
● Reusable XPages
Controls are provided
to assemble custom
apps

19. Sample App: Mobile Notes Documents
● Access Notes documents on mobile devices (e.g. when commuting to work)

22. Access Native Services - Scenarios
● Sub scenarios
─ Local contacts
─ Camera
─ GPS/geolocation
─ Accelerometer
─ Gestures (e.g. shake, orientation change)
─ Local filesystem
─ Media (e.g. pick photo)
© 2011 IBM Corporation 22

23. Sample Scenario:
Take Picture and upload to Domino

24. Access Native Services
● Most of this functionality is not in W ebKit and not in HTML5 or any other
standard or proposal yet
● PhoneGap provides JavaScript APIs to use this functionality
● PhoneGap is a native app and as such needs to be deployed to mobile
devices
● The XPages Mobile Controls project provides a sample how to use PhoneGap
● PhoneGap works on Android, iPhone and Blackberry

27. Offline and cached Data
● HTML5 will support caching of resources and provide local storage
capabilities
● Some W ebKit based browsers support today also SQL storage of data
● Sample:
Same blog
application as
previously taken
offline
© 2011 IBM Corporation 27

28. Offline Implementation
● Usage of manifest file to cache resources
● Usage of 'localSession' to cache data
─ SQL would also be possible but not supported on all W ebKit devices
● Offline detection via JavaScript
● The synchronization and offline mechanism is limited at this point:
─ The synchronization is hardcoded to the last 10 view entries and documents
─ The data is updated automatically when online
─ The content of documents is stored locally but without pictures and other
embedded objects
─ Comments can be read but no new comments can be created offline
