Presentation Transcript

  1. Mobile Application Development

  2. Agenda • Emerging mobile services • Limitations of current technology • Developing mobile applications using Eximius mBaze framework • Bookstore service: an example application

  3. Demand Drivers • Consumer applications • Communication • Entertainment • Enterprise applications • Collaboration • Integration with Personal Information Management Systems (PIM) • New application frontiers • More capable devices open new possibilities

  4. Consumer Applications Messaging Text messaging is the top data service world wide Driven by convenience and simplicity Users want more Use of picture and video messaging significantly increases data traffic Game downloads Driven by availability of better devices and increasing familiarity with mobile internet On the phone games are fast, convenient, have nice user interface Information Retrieval From service provider to users Local news/weather/traffic alert subscriptions via text messaging From users to service providers Surveys, polls, discussions

  5. Enterprise Applications In the enterprise PIM is the king Dedicated devices such as RIM BlackBerry widely used since they provide seamless information sharing with the desktop Always-on pushed-based communication eliminate the need for inconvenient synchronization Increasingly consumer devices come with similar, low-end, built-in PIM software BUT inconvenient Requires synchronization Difficult to share information with the desktop Closed platform, non-extendable ¨HOWEVER, they are programmable J2ME, Symbian Platform, Microsoft Compact .NET It has become possible to have enterprise PIM functionality on low consumer devices!

  6. Emerging Applications Location Based Services Users are already showing interest as illustrated by increasing use of text message alerts on local news/weather/traffic reports Location information available on increasing number of devices Mobile Payments Mobile Ticketing

  7. Mobile application characteristics Programmability Potential for creating more responsive applications (combats bad perception left by WAP) Critical personal data Every application will access personal user profile in some form Customizations, preferences, authentication information, personal information (contacts, tasks, appointments, etc.) Mobile payments (credit cards, account information, e-tickets) Asynchronous Communication Most applications are best described as event-based―core of the application logic is to react to some external events.

  8. Agenda • Emerging mobile services • Limitation of current technology • Developing mobile applications using Eximius mBaze framework • Bookstore service: an example application

  9. Current Technology SMS request-reply” text applications WAP Web applications J2ME Java applications

  10. Example Application Mobile Payments Access to the Internet via a mobile device to buy and sell services Examples: mobile banking, brokerage services, bill payments, information services

  11. Using SMS Insecure Cumbersome to use Users need to remember cryptic SMS commands Cannot store credit card information on the device Limited extensibility Payment history, merchant incentives, etc.

  12. Using WAP • Equivalent to web payments • Slow as pages making up user interface need to be downloaded for every payment • Request-reply interaction incompatible with “Bill notification” • Limited ability to save information locally • Extendable • Can be developed and deployed very quickly

  13. Using J2ME Insecure HTTP request-reply problem (same as for WAP) Requires considerable software development More difficult to deploy Simple, intuitive, pleasing user interface possible Very extendable

  14. Developing Mobile Applications Lower your cost of development Almost all web/desktop/enterprise applications are developed using some framework Mobile Apps are the same, don’t reinvent the wheel! Advantages of a framework The infrastructure is already built for you The infrastructure if maintained for you You can concentrate on developing your application
