Tools and libraries that simplify Location API in Android?

    // Example of using Fused Location Provider from Google's Location Services
    import com.google.android.gms.location.FusedLocationProviderClient;
    import com.google.android.gms.location.LocationServices;
    import com.google.android.gms.tasks.OnSuccessListener;
    import android.location.Location;

    public class LocationActivity extends AppCompatActivity {
        private FusedLocationProviderClient fusedLocationClient;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_location);
            
            fusedLocationClient = LocationServices.getFusedLocationProviderClient(this);
            getLastLocation();
        }

        private void getLastLocation() {
            fusedLocationClient.getLastLocation()
                .addOnSuccessListener(this, new OnSuccessListener() {
                    @Override
                    public void onSuccess(Location location) {
                        // Got last known location, in some rare situations this can be null
                        if (location != null) {
                            double latitude = location.getLatitude();
                            double longitude = location.getLongitude();
                            // Use the location data (latitude and longitude)
                        }
                    }
                });
