In a modern world smartphones became a commonly used electronic devices performing numerous day-to-day tasks and much more. But they require battery power to operate. It is well-known that computationally intensive programs as well as those using different smartphone peripherals tend to discharge the battery much quicker then their less intensive counterparts, leading to a decreased operating time. To make an application energy-aware, developers need tools to analyze its energy consumption. In this paper we present an open-source software framework to create such tools, Navitas Framework, as well as its practical application - an Android Studio IDE plugin to profile energy consumption of an application, Navitas Profiler. We describe design and architecture of the framework, outline plugin capabilities and demonstrate its usage.
