Woodpecker: Identifying and Fixing Android UI Display Issues
Zhe Liu · 2022 IEEE/ACM 44th International Conference on Software Engineering: Companion Proceedings (ICSE-Companion) · 2022
The complexity of GUI and some combinations of personalized settings make the UI display issues occur frequently. Unfortunately, little is known about the causes of UI display issues. The Android fragmentation and variety of UI components post a great challenge to repair the issue. Based on the our empirical study, this paper proposes Woodpecker to automatically detect, localize and repair UI display issues in Android apps. It detects screenshots with issues with computer vision technology, localizes buggy source code from screenshot, and repairs issues with pre-defined templates automatically. We evaluate Woodpecker with 30 real-world UI display issues, it can successfully detect 87% and repair 77% issues. We further apply Woodpecker to another 256 popular open-source Android apps, and successfully uncover 112 previously-undetected issues. It can automatically repair 106 (94%) issues, with 76 of them accepted by developers so far, while others pending (none of them is rejected).
