Abstract

We propose an approach to automatically identify and extract patches from updated Android apps by comparing the updated versions and their predecessors. PEDroid, a prototype patch extraction tool against Android apps, consists of two phases: differential analysis and patch identification. We evaluated it with a set of popular open-source apps to demonstrate its effectiveness. PEDroid achieves a recall of 92% in differential analysis and successfully identifies 28 of 36 patches in patch identification. We also provide specific guidance on reproducing the experimental results.
