Question

I am using location listener in my app.
I have the code like:

    public void startlistning()
    {   
            locationListener = new LocationListener() {
            @Override
            public void onStatusChanged(String provider, int status, Bundle extras) {
                // TODO Auto-generated method stub
            }
            @Override
            public void onProviderEnabled(String provider) {
                // TODO Auto-generated method stub
                Toast.makeText( getApplicationContext(),"Gps Enabled", Toast.LENGTH_SHORT).show();
            }
            @Override
            public void onProviderDisabled(String provider) {
                // TODO Auto-generated method stub
                Toast.makeText( getApplicationContext(),"Gps Disabled", Toast.LENGTH_SHORT ).show();
            }
            @Override
            public void onLocationChanged(Location location) {
                // TODO Auto-generated method stub
                location.getLatitude(); 
                location.getLongitude();
            }
        };
        lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);

But don’t know why the method onLocationChanged did not call when I restart device 1st time (without cellular data (no simcard) available). however, I am using best provider in my app.
Please look into matter. Thanks

Answer 1

Location listener method call when you change the location of device . Its not start when you restart device . If you want to invoke onLocationChanged method you have to change the location of device .

Please try this to get last known location.

    LocationManager locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);

    Criteria locationCritera = new Criteria();
    locationCritera.setAccuracy(Criteria.ACCURACY_FINE);
    locationCritera.setAltitudeRequired(false);
    locationCritera.setBearingRequired(false);
    locationCritera.setCostAllowed(true);
    locationCritera.setPowerRequirement(Criteria.NO_REQUIREMENT);

    String providerName = locationManager.getBestProvider(locationCritera, true);
    Location location  = locationManager.getLastKnownLocation(providerName);

    Log.i("--- Latitude",""+location.getLatitude());
    Log.i("--- Latitude",""+location.getLongitude());
