GPS Lat Lon Issue in Blackberry Storm

问题

I Write the following code in my application. It will run successfully in Simulator but while i m trying to run in my device then it gives Lat & Lon (0.0,0.0). What is the problem.

My Code is .

public class GetLatLon extends TimerTask{
public static Timer timer;
private double longitude;
private double latitude;

public GetLatLon(int duration) {
    timer = new Timer();
    try {
        // TODO: update criteria with desired location distances, etc
        LocationProvider.getInstance(new Criteria()).setLocationListener(
                new MyLocationListener(), 1, 1, 1);
    } catch (Exception e) {
        System.err.println(e.toString());
    }

    timer.schedule(this, 0, 10000);
}

public void run() {
    System.out.println("Lattitude :-"+ latitude);
    System.out.println("Longitude :-"+ longitude);       
}

public double getLongitude() {
    return longitude;
}

public void setLongitude(double longitude) {
    this.longitude = longitude;
}

public double getLatitude() {
    return latitude;
}

public void setLatitude(double latitude) {
    this.latitude = latitude;
}

private class MyLocationListener implements LocationListener {
public void locationUpdated(LocationProvider provider, Location location) {
    if (location != null && location.isValid()) {
        QualifiedCoordinates qc = location.getQualifiedCoordinates()
                     try {
        GetLatLon.this.longitude = qc.getLongitude();
        GetLatLon.this.latitude = qc.getLatitude();
        } catch (Exception e) {
             System.err.println("criccomini " + e.toString());
        }
        } else {
            System.err.println("criccomini location not valid");
        }
    }

    public void providerStateChanged(LocationProvider provider, int newState) {

    }
}

}

I had also faced same problem with 9550 Storm-2. I think you face the problem due to your device GPS value does not initiate properly. Try to use this tool :

http://appworld.blackberry.com/webstore/content/12255

this will initiate the GPS values(Plz don't close this tool just send it to background by pressing red key).After initiate the GPS value try to run you application.

i hope problem will be solved. ;)
