acceptable code coverage since they can only explore a subset of the behaviors
of the applications and do not have full control over the environment
in which they execute. In this work model checking is used to systematically
and more effectively explore application execution paths using state
matching and backtracking. In particular, we extend the Java PathFinder
(JPF) model checking environment for Android. We describe the difficulties
one needs to overcome as well as our current approaches to handling
these issues. We obtain significantly higher coverage using shorter event
sequences on a representative sample of Android apps, when compared
to Dynodroid and Sapienz, the current state-of-the-art dynamic analysis
tools for Android applications.AFRIKAANSE OPSOMMING : Geen Afrikaanse opsomming geskikbaar ni
