What is SensorManager?
The movisens SensorManager provides an easy interface for you to work with your movisens sensors. It allows you to view the details of your sensors configuration, initiate recordings (including delayed start recordings) and retrieve the data captured by the sensor.
Where we register listener of sensor?
Sensor listener. Once you acquired a sensor, you can register a SensorEventListener object on it. This listener will get informed, if the sensor data changes. To avoid the unnecessary usage of battery power, you can register your listener in the onResume() method and de-register it in the onPause() method.
