 Maybe I can be choosy and say that if it GPS then I demand 20 meter accuracy but if it is network then I only demand 500 meter??? Chuck Norris can demand a certain accuracy from GPS - You can't - GPS reports its accuracy to you - It is a function of the number of satellites in view, and other

That was my thought. Unless location provider registration is managed through the variety of app lifecycle state changes, it is easy to put an app in a state where it acquires the device location using Network based location providers, even though the user selected GPS and unselected everything

You can manage the orientation changes yourself and eliminate this source of device confusion, it's quite easy, just add android:configChanges=orientation to your manifest's activity. As for the signal source, just make sure to check your provider for gps - if it says gps, it will be from that

In answer to some questions. I am setting up the network location finder and the GPS location finder using 2 separate LocationListeners. I have some logic that determines what the user has activated so I only listen to gps if the have gps enabled and so forth. From my user feedback it seems

I have had the same reports from my user community within my GPS application for Android. In my support emails I have been telling them that it is most likely a hardware/OS issue, and a hard reset (battery pull) should fix it. I have had a few users reply back and said that has fixed it. I

Question: How are you getting your location fix? Are you using ACCURACY_FINE and assuming it will use the GPS? Unless you specifically test for the provider being GPS, it might default to network, which would give you a position with limited accuracy. I've seen this bouncing around effect when the

A GPS fix can be inaccurate - no matter how confident the GPS device is :) My experience here is from GPS units mounted on multiple trains travelling about the UK, recording their position every few seconds. A small percentage of the values we recieved from the GPS units were completly
