Given the facts of more and more available smart phones and mobile distribution channels, e.g. Apple App Store, the emerging logging observation method gains an increasing attention. In this paper we report on our experiences of conducting a user study in the Android Market by relying on the logging methodology, and thus on sensors of a common mobile smart phone. Based on our preliminary findings we identify the major challenges a researcher needs to face, when an in-market study should be conducted.} @COMMENTBibtex file generated on
