Well, then the docs or the implementation should be fixed and you are welcomed to wait when it will be resolved ;)
The concept of "getBestProvider" assume you have hundreds of providers but don't know what is the best one. In the reality there are only 2 providers available on most of the production level Android devices: network and GPS. So if you want to make sure your code uses network provider then use its name directly, for example: locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener); When you prefer to use GPS use LocationManager.GPS_PROVIDER You don't need to use an API just because someone published it, especially when it doesn't work as you expect.
