GPS and internet connection

Hardware (GPS, accelerometer, etc.)
#1

Hi

I am working on app which will use custom map for offline navigation.

Idea is to not to use internet connection at all (which means no native.mapView).

My question is: does GPS events need internet connection?

I think I saw somewhere that GPS have some issues on Android… 

I hope I am wrong :slight_smile:

Hi @srdjan,

It basically depends on the device. “agps” (assisted GPS) works with cellular and/or Wi-Fi data, and it’s more accurate because it can triangulate the location better. But, many devices can work without internet to get a basic GPS location… just be aware that it takes longer, and it’s not as accurate… sometimes the location can be in error of 800-1000 meters, which isn’t necessarily good. :stuck_out_tongue:

This document specifies a bit more about it, and which settings you can use with Android:

Hope this helps,
