java - Android GPS Scatter points when entering a building -


i busy implementing tracking app app tracks go , plot path on google maps. when test , entered building scatter coordinates.

i know because gps network not available inside building , switch on phone's networking , therefore gets scatter coordinates. have used kalman filter make points more smooth.

how can prevent coordinates scattered?

inside building location attribute "horicontal accuracy estimate" (or similar called) higher.

as first approach ignore location have horacc higher 30m.
additionally may ignore locations not delivered gps_provider.
