FicFinder Project

Fragmentation-Induced Compatibility Issue Finder

FicFinder project aims to help Android app developers to solve Android fragmentation-induced compatibility issues. We started from an empirical study of 191 real-world FIC issues to understand and characterize FIC issues. Based on the empirical findings, we proposed API-context pair to model FIC issues.

With API-context pair model, we develop FicFinder on top of Soot framework. FicFinder successfully detected 14 previously-unknown FIC issues, among which eight were acknowledged by the app developers and five critical ones were quickly fixed.
