Abstract-Over the last three years, Android has established itself as the largest-selling operating system for smartphones. It boasts of a Linux-based robust kernel, a modular framework with multiple components in each application, and a securityconscious design where each application is isolated in its own virtual machine. However, all of these desirable properties would be rendered ineffectual if an application were to deliver erroneous messages to targeted applications and thus cause the target to behave incorrectly. In this paper, we present an empirical evaluation of the robustness of Inter-component Communication (ICC) in Android through fuzz testing methodology, whereby, parameters of the inter-component communication are changed to various incorrect values. We show that not only exception handling is a rarity in Android applications, but also it is possible to crash the Android runtime from unprivileged user processes. Based on our observations, we highlight some of the critical design issues in Android ICC and suggest solutions to alleviate these problems.
The robustness of inter-component communication in Android has been studied also by Maji et al. through fuzzy testing techniques, exposing some interesting findings REF .
