  1. Mobile Development • Presented by: • Samantha C. Tomeï • CMPS 5143 • Adv. Software Engineering • Midwestern State University • October 11, 2012

  2. Overview • Introduction • Brief overview research papers • Software Engineering Issues • Survey Results • What Makes Mobile Development Different? • Model-Driven Development (MobiA tool) • Test-Driven Development • Android Developer Guide • Conclusion • References

  3. Introduction • Apple App Store opened in July 2008 • Google Play – October 2008 • Blackberry App World – April 2009 • Nokia Store – May 2009 • Windows Phone Marketplace – October 2010

  4. Survey Results • Most applications were relatively small • Averaging several KLOC • One or two developers • Two main categories • Native applications • Web applications • “Best practices” were adhered to quite well • Rarely used formal development processes • Very little organized tracking of development efforts and gathered few metrics

  5. What Makes Mobile Development Different? Common issues: • Integration with device hardware • Security • Performance • Reliability • Storage limitations Additional requirements: • Interaction with other applications • Sensor handling • Native and hybrid apps • Families of hardware and software platforms • User interfaces • Complexity of testing • Power consumption

  6. MobiA • Mobile Application (MobiA) modeler • Model Driven Development (MDD) • Create high-level, platform independent model of the system • Generate specific code based on the model for the target system

  7. Test-Driven Development (TDD) • TDD – evolutionary software development technique • Reduces time wasted on debugging • Speeds up the development process • Develops more reliable software Process: • Tests prepared by dividing the software functions into small units • Developers generate automated unit tests • Otherwise tests not performed frequently enough • Software developed based on unit tests
