/**
 * Register a {@link android.hardware.SensorEventListener} for the sensor and max batch delay.
 * The maximum batch delay specifies the maximum duration in microseconds for which subsequent
 * sensor events can be temporarily stored by the sensor before they are delivered to the
 * registered SensorEventListener. A larger delay allows the system to handle sensor events more
 * efficiently, allowing the system to switch to a lower power state while the sensor is
 * capturing events. Once the max delay is reached, all stored events are delivered to the
 * registered listener. Note that this value only specifies the maximum delay, the listener may
 * receive events quicker. A delay of 0 disables batch mode and registers the listener in
 * continuous mode.//from  www .j a v  a 2s.  c o  m
 * The optimium batch delay depends on the application. For example, a delay of 5 seconds or
 * higher may be appropriate for an  application that does not update the UI in real time.
