Hi All

I need to get the current location coordinates on the start of the app.Iam working out in 8520 simulator.

Iam trying out with a sample code here but getting the location=null in 8520 simulator and in 9800 simulator iam getting the coordinates as 43.6775,-80. 7339

Criteria criteria = new Criteria();
        criteria.setVerticalAccuracy(50);
        criteria.setHorizontalAccuracy(50);
        criteria.setCostAllowed(true);
        criteria.setPreferredPowerConsumption(
        Criteria.POWER_USAGE_HIGH);
        try {
        screen.setMessage("Getting location...");
        LocationProvider provider =
        LocationProvider.getInstance(criteria);
        Location location = provider.getLocation(-1);
        QualifiedCoordinates qualifiedCoordinates =
        location.getQualifiedCoordinates();
        screen.setLocation(qualifiedCoordinates.getLongitude(),
        qualifiedCoordinates.getLatitude());

Plzzzz any help....

Thanks.

Have a good look at this KB article and the code supplied is useful too:

If you look at the Simulator, in the 'Windows' menu you will see a Simulate menu option, click on that and you will see for most devices, a GPS option.  This is the location that it will get when using GPS.  I'm not sure how you can simulate any of the other location options, but if you change this I suspect it might change the others too.

You can use this code for getting current location ... Dont use this code directly. plz understand than use...

Class test

{

Criteria criteria;

LocationProvider locationProvider;

switch (MODE) {
case Constants.GPS_MODE_SATELLITE:  //1
criteria.setCostAllowed(false);
break;
case Constants.GPS_MODE_CELLSITE:   //2
criteria.setHorizontalAccuracy(Criteria.NO_REQUIREMENT);
criteria.setVerticalAccuracy(Criteria.NO_REQUIREMENT);
criteria.setCostAllowed(true);
criteria.setPreferredPowerConsumption(Criteria.POWER_USAGE_LOW);
// Will wait for two minutes
criteria.setPreferredResponseTime(120000);
break;
}

private LocationProvider getLocationProvider() throws LocationException {
return LocationProvider.getInstance(criteria);
}

}
