Though there is evidence that presenting Android app permission information to the user in a clear, more contextdependent way can influence mobile phone users in choosing apps that request fewer permissions [4], ultimately users still tend to make poor privacy and security decisions, especially when warnings are unclear or inhibitive [1]. As a result, we believe that code developers should take...

Android is among the new breed of smartphone software stacks. It is powerful yet friendly enough to be widely adopted by both the end users and the developer community. This adoption has led to the creation of a large number of thirdparty applications that run on top of the software stack accessing device resources and data. Users installing third party applications are provided information abo...

Mobile devices such as cellular phones (CPs) are crucial in our daily life. A lot of work has been done to handle the problems of designing and developing of GUI and applications for CPs. In this paper, we survey the existing strategies to design and implement of GUI for CPs. In addition, the paper reviews the methods to develop the applications for CPs and the guidelines to overcome the proble...

As the mobile platform pervades human life, much research in recent years has focused on improving the reliability of mobile applications on this platform, for example by applying automatic testing. However, researchers have primarily considered testing of single version of mobile applications. Although regression testing has been extensively studied for desktop applications, and many efficient...
