This is an easy way to accomplish this. Adapt it to your Fragment or Activity, add the manifest permission and don't forget to update the location of your emulator (in case you are using one).

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
public class MyFragment extends Fragment implements
        ConnectionCallbacks, OnConnectionFailedListener, LocationListener {


    private GoogleApiClient mGoogleApiClient;
    private LocationRequest mLocationRequest;

    public MyFragment() {
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View view = //...

        // your stuff

        buildGoogleApiClient();

        return view;
    }


    @Override
    public void onStart() {
        super.onStart();
        mGoogleApiClient.connect();
    }

    protected synchronized void buildGoogleApiClient() {
        mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
    }

    protected void createLocationRequest() {
        mLocationRequest = new LocationRequest();
        mLocationRequest.setInterval(10000);
        mLocationRequest.setFastestInterval(5000);
        mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    }

    protected void startLocationUpdates() {
        Log.i(TAG, "Started listening for location updates...");
        LocationServices.FusedLocationApi.requestLocationUpdates(
                mGoogleApiClient, mLocationRequest, this);
    }

    protected void stopLocationUpdates() {
        Log.i(TAG, "Stopped listening for location updates");
        LocationServices.FusedLocationApi.removeLocationUpdates(
                mGoogleApiClient, this);
    }

    @Override
    public void onConnected(Bundle connectionHint) {
        Log.i(TAG, "Connected");
        createLocationRequest();
        startLocationUpdates();
    }

    @Override
    public void onConnectionFailed(ConnectionResult result) {
        Log.i(TAG, "Connection failed: ConnectionResult.getErrorCode() = " + result.getErrorCode());
    }


    @Override
    public void onConnectionSuspended(int cause) {
        Log.i(TAG, "Connection suspended");
        mGoogleApiClient.connect();
    }


    @Override
    public void onLocationChanged(Location location) {
        double latitude = location.getLatitude();
        double longitude = location.getLongitude();

        stopLocationUpdates();

        // do whatever you want to do with lat and long
    }
}

I didn't get how to make this work out.

Can you please share project included with location code.
