Getting Location Updates Based On Time Interval Or Displacement

I am using Fused Location Api to get location updates. When I set x seconds as time interval then I got onLocationChanged() called after every x seconds. And when I set 10 meter as

Solution 1:

Only for displacement

  mLocationRequest.setInterval(0);
  mLocationRequest.setFastestInterval(0);
  mLocationRequest.setSmallestDisplacement(SMALLEST_DISPLACEMENT);

Only for interval

 mLocationRequest.setInterval(POLLING_FREQ);
 mLocationRequest.setFastestInterval(FASTEST_UPDATE_FREQ);
 mLocationRequest.setSmallestDisplacement(0); // Not needed, already default value is 0

Normally interval and distance params are being calculated with AND. It means when you change your position at least SMALLEST_DISPLACEMENT meter AND at least POLLING_FREQ milliseconds have passed, then onLocationChanged() will be fired.
