This paper presents a modular context provisioning middleware for the support of ubiquitous services and applications, entitled C-ProMiSE ("Context Provisioning Middleware with Support for Evolving Awareness"). Special emphasis is put on a smartphone application which serves the middleware with primitive context originating from diverse physical, virtual and logical sensors (e.g. GPS, accelerometers, address book). Besides general design principles, a specific implementation based on the Android OS is prototyped and quantitatively evaluated. Since limited battery power is a major concern in smart mobile devices, the energy consumption by the prototype contextual application is also determined.
