Wearable devices like smartwatches conquer the market and simplify our everyday life. Mostly, these devices are connected to our mobile phones, helping us to make communication easier and faster. However, wearable devices feature plenty of sensors and network interfaces that are mostly unused. Thus, the question arises on how to use this potential to improve the functionality and user experience of handset applications. This paper presents a framework for the Android operating system which enables us to retrieve information from the wearable device and store and use it on the handheld device. The primary focus lies on sensor and network interfaces, and as a result, this information can be considered for further computations. We offer the framework as an Android library which can be included in all Android projects. We evaluate the framework by conducting network performance tests as well as tests regarding CPU, memory and battery usage, and achieve promising results. Concluding, we can say that the wearable technology offers lots of opportunities for present and future Android projects. Due to the different types of framework services, we achieve the goal of providing a broad base of information that can be utilized by all developers.
