Context awareness is obtaining more and more vital for variety of mobile and pervasive applications on these days smartphones. Whereas human centric contexts(e.g. indoor/outdoor, at homing/office, driving/walking) are extensively researched, few tries have studied from phones perspective(e.g. on table/sofa, in pocket/bag/hand). Thus everyone including us tend to ask such immediate surroundings as micro-environment typically many to a dozen of centimeters, around a phone. Styling and implementing good smart application, a micro-environment sensing platform that automatically records sensing data information and characterize the micro-environment of smartphones, is the main aim. The platform runs as a daemon process on a smartphone and provides finer-grained atmospheric information to upper layer applications via programming interfaces. Smart android application is a unified framework covering major cases of phone uses, placement, perspective and interaction in sensible uses with sophisticated user habits. As a protracted term running middleware, smart android applications consider both energy consumption and user friendly relationship.
