Ayushman Jain presented on collaborative and agile development of mobile applications using Rational tools. The presentation covered the evolution of mobile technology, trends in mobile application development, and challenges for development teams. It described how Rational Team Concert, Rhapsody, Application Developer, and other Rational tools can help development teams address these challenges and enable collaborative, model-driven development. The presentation also provided examples of developing Android, Blackberry, web-based, hybrid, and Java ME applications using Rational tools.

Evolution of Mobile phones
 20 years ago – calling, texting. Now- everything (well almost!).
 Technology has advanced rapidly.
 Some problems on the way:
– lack of powerful mobile platforms and operating systems.
– Porting apps to new phones and operating systems coming out in rapid succession.
 JAVA MIDlets – first solution – restricted access to hardware.
 iPhones with iOS came next – but proprietary.
 Android – access device hardware, share apps, etc. – by far the most flexible.

4. The Mobile Age
 Mobile computing growing exponentially.
 By the end of 2014, Gartner forecast over 185 billion applications will have been
downloaded from mobile app stores, since the launch of the first one in July 2008.

5. The Mobile Age
 Mobile in B2C
– Enable banking, insurance, retail, trading anytime anywhere.
 Mobile in B2E and B2B
– Empower field employees.
– Increase efficiency in supply chain.
– Exchange business information.

8. Challenges for mobile development teams
 Manage ever-increasing complexity of mobile applications
– Rapidly evolving mobile hardware and user interface
– Security, communication, data, social interactions, touch-friendly UI, multiple platforms.
 Manage multiple disciplines – stakeholders, developers, testers, project managers.
 Manage activities that span the entire lifecycle - gather requirements, model and design
mobile apps, develop, test and deploy.
 Visibility and traceability across the board.
 Efficient communication and coordination.
 Using tools that facilitate and enable, rather than inhibit.
IBM Rational tools such as Rhapsody, Rational Team Concert, and Rational
Application Developer help address these challenges.

14. • Rhapsody provides models for all android classes and widgets.
• Drag and drop widgets into the model.
• Navigate to source code from model and vice versa.
14 © 2011 IBM Corporation

15. • Classes can be updated in the model - source code automatically generated and
vice versa.
• Enables code centric development and model centric development.
15 © 2011 IBM Corporation

16. • Use-case diagrams can be added, linked to requirements imported from another
tool such as Rational DOORS.
16 © 2011 IBM Corporation

17. • Source code can be shared using Jazz source control in RTC.
• Change sets can be associated with RTC work items.
17 © 2011 IBM Corporation

18. • Emulator configurations can also be shared under source control – ensures consistency
across the team.
18 © 2011 IBM Corporation

19. How to maintain records of relevant mobile device configurations?
• Include the information in fields in the work items.
• Helps bug filing and tracking – include info about problem as seen in a device
configuration.
19 © 2011 IBM Corporation

20. • RTC Snapshot tool – take snapshots of expected emulator output, models, buggy UI.
• Snapshots can be attached to work items for reference or bug demonstration.
20 © 2011 IBM Corporation

21. • Rhapsody DiffMerge tool – compare your model with the one in central repository and
merge changes using the visual editor.
21 © 2011 IBM Corporation

22. • RTC Junit integration – create defects from failing tests.
• Duplicate stack traces automatically found by RTC.
22 © 2011 IBM Corporation

23. • RTC Web UI – for non-coding tasks.
• View project dashboard, plans, work items, builds, reports, etc all in the browser.
• Windows mobile development can be done using RTC Visual Studio client.

24. Develop Blackberry applications too!
 The Blackberry JDE (Java Development Environment) can be installed on the latest RTC
distro.
 Latest simulators can be downloaded and different configurations can be released into RTC
source control.

26. Using Rational Application Developer(RAD) and Maqetta to develop
web based mobile applications
26 © 2011 IBM Corporation

27. What is dojox.mobile
 A dojo based widget set for creating mobile applications.
– Available since dojo 1.5.
 Aims to provide lightweight UI widgets.
– Cannot do native device functionality.
 Allows customization of app look and feel.
– Device-specific or device-neutral.
– Comes with iOS, Android and Blackberry themes currently.
 Server technology agnostic.
27 © 2011 IBM Corporation

28. Maqetta
 Open source project hosted by Dojo foundation.
 Enables WYSIWYG visual authoring
of HTML5 and dojo applications.
 Easily modify the stylesheet.
 View the same app for different
platforms.
 Test the app on the browser itself.
28 © 2011 IBM Corporation

29. • RAD offers a Rich Page editor that uses browsers as rendering engines.
• A visual editing experience with drag-and-drop and direct page manipulation.
29 © 2011 IBM Corporation

30. • RAD also offers browser-based test emulators – helps testing the mobile app on various
platforms.

32. Developing hybrid mobile applications
 Example - web-based movie ticket booking application that lets you invite friends from the
phone contact book.
 How can you query the platform's contact book from within your web app?
 How can you do so in a platform agnostic way?
 Phonegap shows the way - provides javascript APIs which abstract the platform's native
services.
 Phonegap plugin for Eclipse integrates well with Rational tools.
 Develop an app using HTML5, Dojo, javascript once. Package it for various platforms using
Phonegap.
 Use any UI toolkit – Dojox.mobile, Sencha touch, Titanium, etc.
 Facebook connect plugin NEW

33. Developing Java ME applications
 Android, iOS getting popular, but majority of people still
own older handsets.
 Developer Economics 2010 and Beyond - Java ME as a
platform has an installed base of 3,000 million devices:
– 150 times that of Android,
– 50 times that of iOS.
 Mobile Tools for Java (MTJ) is an Eclipse plugin, which
powers RTC for Java ME applications.

34. Test mobile applications with Rational Quality Manager
• RQM integrates with DeviceAnywhere.
• Write a single automated test script.
• Test applications on a device cloud/device farm.
• Failures with screenshots captured in a defect by RQM and routed to developers.
