public class ContextExample1 extends androidx.appcompat.app.AppCompatActivity implements ContextListener, SensorValueListener
A location-based context example test application. This example creates two location-based contexts named "At home" and "At work". The location contexts (instances of the class LocationContext) take the coordinates (lat, lon) and radius (in meters) as input, which values define the area (circle) where the context is active. Further, the example shows how to receive updates to the contexts active value. For example context type and sensor type implementations:- See Also:
