Android Sensor Programming By Example

Time for action - using sensors in the foreground activity

In this section, we will explore how to use sensors in the activity. This is the most basic and straightforward way of using sensors. Also, it's the most efficient way if your sensor functionality only ties to that activity:

1. The first step is to implement our activity with the SensorEventListener interface so that our activity can receive SensorEvent through the onSensorChanged() method. The following code snippet shows the necessary import statements and the class declaration:
