GPS without network access?

claudette · by **claudette** » Tue Feb 23, 2010 4:16 pm

I am using the Motorola Milestone (Droid).

I need to use GPS without network connection. But after I set a GPS location listener, I get the network error "Unresolved host address" (see below). On the device I do not have any network access at the time I try to start the GPS localisation. Is there no way to use GPS without network access?

Best regards,

claudette

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mLocationListener);

this works but make sure you add the correct permissions in your manifest

thank you for your response djmason9!

but unfortunately it doesn't work on a motorola milestone! are you using a motorola milestone?
if I run the application on a samsung mobile, I get the latitude and longitude values.
it seems as if the error is been caused by a motorola class.

has anybody noticed that problem and has a solution?

thank you!

kind regards,
claudette
