ANCHOR: locating android framework-specific crashing faults

Android framework-specific app crashes are hard to debug. Indeed, the callback-based event-driven mechanism of challenges crash localization techniques that developed for traditional Java programs. The key challenge stems from fact buggy code location may not even be listed within stack trace. For example, our empirical study on 500 an open benchmark has revealed 37 percent types related bugs outside traces. Moreover, programs a mixture and extra-code artifacts such as Manifest file. any artifact can lead failures in execution creates need position target beyond realm. In this paper, we propose Anchor , two-phase suspicious bug suggestion tool. specializes finding crash-inducing is lightweight source independent since it only requires message apk file locate fault. Experimental results, collected via cross-validation in-the-wild dataset evaluation, show effective locating crashing faults. Finally, put results openly accessible at https://github.com/anchor-locator/anchor .
