SensorEventListener2

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.
