locationmanager - What is the use of "Maintain a current best estimate" of location Android? -


i've read the documentation , this.

what don't understand why function isbetterlocation() exists. function tells difference between "current location fix" , "new location". 2 locations really?

i can think of

  • last location stored in application preferences, database etc. , location retrieved location provider e.g. gps
  • location retrieved location provider , latest location gotten through onlocationchanged()

in either case, latter more up-to-date; therefore, more accurate. so, why bother making comparison @ all?
explanation can think of more up-to-date location information isn't more accurate. true?

take here http://developer.android.com/guide/topics/location/strategies.html, there explanation on page (android documentation)
