Used for receiving a notification when a flush() has been successfully completed.
void onFlushCompleted (Sensor sensor)
Called after flush() is completed. All the events in the batch at the point when the flush
was called have been delivered to the applications registered for those sensor events. In
KITKAT, applications may receive flush complete events
even if some other application has called flush() on the same sensor. Starting with
LOLLIPOP, flush Complete events are sent ONLY to the
application that has explicitly called flush(). If the hardware FIFO is flushed due to some
other application calling flush(), flush complete event is not delivered to this application.
Sensor on which flush was called.
