Mobile devices (such as smart phones, etc.) are ubiquitous now. With advances in hardware, present application mobile devices are capable of running almost anything. Today, there is a growing demand to port many of the advanced application and software systems to smaller mobile device platforms. Reengineering an old system often assures better return of investment than development from scratch and it is also considered to be a popular trouble shooting technique. Existing systems are reengineered to improve maintainability, to port a system into a new platform, to position a system for major enhancements or to increase reusability.
