How do I get the current GPS location programmatically in Android?

Question

I need to get my current location using GPS programmatically. How can i achieve it?

Answer 1

I have created a small application with step by step description to get current location's GPS coordinates.

Complete example source code is in Get Current Location coordinates , City name - in Android.

See how it works:

• All we need to do is add this permission in the manifest file:

  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
  

• And create a LocationManager instance like this:

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

• Check if GPS is enabled or not.

• And then implement LocationListener and get coordinates:

  LocationListener locationListener = new MyLocationListener();
  locationManager.requestLocationUpdates(
  LocationManager.GPS_PROVIDER, 5000, 10, locationListener);
  

• Here is the sample code to do so

/*---------- Listener class to get coordinates ------------- */
private class MyLocationListener implements LocationListener {

    @Override
    public void onLocationChanged(Location loc) {
        editLocation.setText("");
        pb.setVisibility(View.INVISIBLE);
        Toast.makeText(
                getBaseContext(),
                "Location changed: Lat: " + loc.getLatitude() + " Lng: "
                    + loc.getLongitude(), Toast.LENGTH_SHORT).show();
        String longitude = "Longitude: " + loc.getLongitude();
        Log.v(TAG, longitude);
        String latitude = "Latitude: " + loc.getLatitude();
        Log.v(TAG, latitude);

        /*------- To get city name from coordinates -------- */
        String cityName = null;
        Geocoder gcd = new Geocoder(getBaseContext(), Locale.getDefault());
        List<Address> addresses;
        try {
            addresses = gcd.getFromLocation(loc.getLatitude(),
                    loc.getLongitude(), 1);
            if (addresses.size() > 0) {
                System.out.println(addresses.get(0).getLocality());
                cityName = addresses.get(0).getLocality();
            }
        }
        catch (IOException e) {
            e.printStackTrace();
        }
        String s = longitude + "\n" + latitude + "\n\nMy Current City is: "
            + cityName;
        editLocation.setText(s);
    }

    @Override
    public void onProviderDisabled(String provider) {}

    @Override
    public void onProviderEnabled(String provider) {}

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {}
}
