Android Question How top retrieve location over mobile network

[Christopher]

hi,

I have successfully obtained relatively accurate position with Location.Manager over wifi. With Wifi absent however, I get the "coarse" position. When I activate data access over mobile network on my phone (and I can connect to internet) I still get the "coarse" result. Is there a way of getting the "fine" results with data enabled over mobile access ? If not, would it be possible to go to google maps and retrieve my location ? This info is for a mobile app. on a phone not tethered to wifi.

Thanks

Chris

Have you seen this library? http://www.b4x.com/android/forum/threads/locationmanager-library.13337/

Yes. I am using that library. With wifi on it yields "accuracy : 50" with wifi off it yields "accuracy: 1529". My question is whether with mobile data enabled (internet access) whether accuracy can be improved to similar level as with wi-fi on.

thanks

Then the answer is going to be no. Have a look at these:

I have read them. I guess this is why most vehicle tracking systems use a separate gps device for tracking.


Thank You

I note that when I have turned off wi-fi and enabled 'data over mobile networks' on my mobile phone, google maps is able to accurately locate my position. Is there an API which would allow me to retrieve my coordinates (do same as Google with same accuracy) from my phone with data over mobile ?

Thanks
