A Detailed Comparison of the Effects of Code Refactoring Techniques in Different Mobile Applications

摘要

Due to the high usage of mobile applications among end users, developers are required to maintain and extend mobile application code. Fowler Martin introduces refactoring techniques to make software code readable, understandable, extensible and more efficient. When refactoring techniques are applied to mobile application code, they affect the energy efficiency and performance of mobile applications. In our previous study, we implemented Fowler’s sample code into a mobile application and used Greenup, Powerup, and Speedup (GPS-UP) metrics to evaluate and categorize the impact of refactoring techniques. However, Fowler’s sample code is simple and does not reflect an accurate evaluation of the refactoring techniques. Thus, we extend our work through presenting a case study that evaluates and categorizes the impact of refactoring techniques when they are applied to open-source mobile applications. In addition, we provide a comparison of the effect of refactoring techniques between the results of this study and our previous one.
