Called when there is a new sensor event.  Note that "on changed"
is somewhat of a misnomer, as this will also be called if we have a
new reading from a sensor with the exact same sensor values (but a
newer timestamp).
See SensorManager for details on possible sensor types. 
See also SensorEvent. 
NOTE: The application doesn't own the event object passed as a parameter and therefore cannot hold on to it. The object may be part of an internal pool and may be reused by the framework. 
Params:
