How to get accuracy of GPS in Android -


i need check accuracy of gps... when use location.getaccuracy doesn not return me value... take time..if takes time how long takes?

in android devices, can have 2 sources can position info : gps_provider , network_provider

gps_provider uses gps chipset position fix. has greater accuracy.

network_provider uses information cell-tower triangulate location. hence accuracy not quite good.

you can accuracy info location.getaccuracy() or nmea data.

does take time..if takes time how long takes

once you've started getting fixes won't take time. time first fix can 30 seconds 15 minutes. depends on gps chipset, terrain conditions, cold/warm start etc.

to choose best provider read article
