Android Sensor Programming By Example

Components of the sensor framework

Android has provided methods, classes, and interfaces for accessing sensors and their data that is available on an Android device. These sets of methods, classes, and interfaces are collectively referred to as the sensor framework and are a part of the android.hardware package. It consists of four major components: SensorManager, Sensor, SensorEvent, and SensorEventListener. The entry point to the framework is the SensorManager class, which allows an app to request sensor information and register to receive sensor data. When registered, sensor data values are sent to a SensorEventListener interface in the form of a SensorEvent class that contains information produced from a given sensor. Let's look at each component ...
