## Abstract (arXiv)

Automating the detection of EU General Data Protection Regulation (GDPR) violations in source code is a critical but underexplored challenge. We introduce GDPR-Bench-Android, the first comprehensive benchmark for evaluating diverse automated methods for GDPR compliance detection in Android applications. It contains 1951 manually annotated violation instances from 15 open-source repositories, covering 23 GDPR articles at file-, module-, and line-level granularities. To enable a multi-paradigm evaluation, we contribute Formal-AST, a novel, source-code-native formal method that serves as a deterministic baseline. We define two tasks: (1) multi-granularity violation localization, evaluated via Accuracy@textitk; and (2) snippet-level multi-label classification, assessed by macro-F1 and other classification metrics. We benchmark 11 methods, including eight state-of-the-art LLMs, our Formal-AST analyzer, a retrieval-augmented (RAG) method, and an agentic (ReAct) method. Our findings reveal that no single paradigm excels across all tasks. For Task 1, the ReAct agent achieves the highest file-level Accuracy@1 (17.38%), while the Qwen2.5-72B LLM leads at the line level (61.60%), in stark contrast to the Formal-AST method's 1.86%. For the difficult multi-label Task 2, the Claude-Sonnet-4.5 LLM achieves the best Macro-F1 (5.75%), while the RAG method yields the highest Macro-Precision (7.10%). These results highlight the task-dependent strengths of different automated approaches and underscore the value of our benchmark in diagnosing their capabilities.
