Code Authorship and Fault-proneness of Open-Source Android Applications

Context: In recent years, many research studies have shown how human factors play a significant role in the quality of software components. Code authorship metrics have been introduced to establish a chain of responsibility and simplify management when assigning tasks in large and distributed software development teams. Researchers have investigated the relationship between code authorship metrics and fault occurrences in software systems. However, we have observed that these studies have only been carried on large software systems having hundreds to thousands of contributors. In our preliminary investigations on Android applications that are considered to be relatively small, we observed that applications systems are not totally owned by a single developer (as one could expect) and that cases of no clear authorship also exist like in large systems. To this end, we do believe that the Android applications could face the same challenges faced by large software systems and could also benefit from such studies.
