How to Get an Android Device\'s Latitude and Longitude?

Obtaining Latitude and Longitude of a Mobile Device in Android

Question:
How can I access the current Latitude and Longitude of an Android device using location tools?

Answer:
Utilize the LocationManager class:

LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE); // Obtain the LocationManager
Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER); // Get the last known GPS location
double longitude = location.getLongitude(); // Extract longitude
double latitude = location.getLatitude(); // Extract latitude

If no current location is available, getLastKnownLocation() may return null. To receive asynchronous location updates, consider providing a LocationListener to requestLocationUpdates():

private final LocationListener locationListener = new LocationListener() {
    @Override
    public void onLocationChanged(Location location) {
        longitude = location.getLongitude();
        latitude = location.getLatitude();
    }
};

lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 2000, 10, locationListener);

Ensure your application has the ACCESS_FINE_LOCATION permission for GPS usage:

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

For improved accuracy, you can consider adding the ACCESS_COARSE_LOCATION permission and determining the best provider using getBestProvider().
