Dear all,
I am facing a strange issue and I'm certainly doing something
wrong ...
Here is the scenario :
I open my emulator
I send a geo fix via telnet
I open my app and try to be geolocated... getLastKnownLocation return
null (the first time, or the last position after opening "Map"), my
code is below
I open the "Maps" included app from Google.
I click on menu > My Location and I am located to the position I sent
via the geo fix
I reopen my app and try to be geolocated ... and it works !
I read the doc and I don't understand what I am doing wrong :
Here is my code :
public static LocationProvider getLocationProviderToUse(Context act)
{
LocationManager locMgr = MapUtility.getBuiltLocationManager
(act);
String name = locMgr.getBestProvider(new Criteria(), true);
Log.d("MAP", "The best location provider is " + name);
return locMgr.getProvider(name);
}
public static GeoPoint geoLocalize(Activity act)
throws SecurityException {
LocationProvider toUse = getLocationProviderToUse(act);
LocationManager locMgr = MapUtility.getBuiltLocationManager
(act);
// Test but change nothing
// LocationListener listener = new LocationListener() {
// public void onLocationChanged(Location location) {
// }
// public void onProviderDisabled(String provider) {
// }
// public void onProviderEnabled(String provider) {
// }
// public void onStatusChanged(String provider, int
status,
// Bundle extras) {
// }
// };
// locMgr.requestLocationUpdates(toUse.getName(), 0, 0,
listener);
Location current = locMgr.getLastKnownLocation(toUse.getName
());
if (current != null) {
Log.d("MAP", "Location : " + current.getLatitude() + ", "
+ current.getLongitude());
GeoPoint p = new GeoPoint((int) (current.getLatitude() *
1000000), (int) (current.getLongitude() * 1000000));
return p;
} else{
Log.e("MAP", "Unable to get the last known position");
return null;
}
}
public static LocationManager getBuiltLocationManager(Context ctx)
{
LocationManager mgr = (LocationManager) ctx.getSystemService
(Context.LOCATION_SERVICE);
return mgr;
}
-----------------------------------------------------
Coud you please help me in finding what is wrong or sending me a code
snippet ? By reading the Google reference documentation, a single call
to getlastknownlocation might be sufficient.... The best provider
returned is always "gps".
Thanks a lot for your help
