问题
I'm developing an android application that involves the detection of the users' location. What I would like to know is, how does this -> LocationManager.GPS_PROVIDER work?
Does it uses the GPS system in the phone or does it uses the mobile company's area network location?
Whenever I turn on the GPS system in my phone, the map would not load. It will only be able to detect & pinpoint the location when I deactivate it. I think the application is tapping into the GPRS or something.
Thanks.

LocationManager.GPS_PROVIDER uses GPS and LocationManager.NETWORK_PROVIDER uses mobile network. Map application works with both of them, it displays the most accurate data that is available from any of the providers.

In reality, GPS is accompanied with Wi-fi or 3G to location searching because the GPS providers is not always available.
