State-taint analysis for detecting resource bugs

In this paper, we propose a static analysis called state-taint analysis to detect resource bugs. Taking the open-but-not-used problem into account, we specify the appropriate usage of resources in terms of resource protocols. We then propose a taint-like analysis which employs resource protocols to guide resource bug detection. As an extension and an application, we enrich the protocols with the inappropriate behaviours that may cause energy leaks, and use the refined protocols to guide the analysis for energy leak detection. We implement the analysis as a prototype tool called statedroid. Using this tool, we conduct experiments on several real Android applications and test datasets from Relda and GreenDroid. The experimental results show that our tool is precise, helpful and suitable in practice, and can detect more energy leak patterns.
