Android - Cant get latitude/longitude value to store and pass on variable

Question

I am trying to store the latitude/longitude to variables x3 and x4 to pass on Spot[] array but it returns 0. I tried printing it on onConnected method and it works fine.

You can call add marker after getting lat/long and also can move camera on that for reference you can check following code

 public class MapDialogFragment extends DialogFragment implements LibListner, OnClickListener, OnInfoWindowClickListener {

private View dialog;
private MarkerOptions markerOptions;
private SupportMapFragment mMapFragment;
private GoogleMap mMap;
private TextView tvBackText, tvback;
// private ArrayList<String> getClickedTitle;
private ArrayList<Data> newData;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    // Utility.Log("onCreateView");
    getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
    // //
    getDialog().getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    // getDialog().getWindow()
    // .getAttributes().windowAnimations = R.style.DialogAnimation;
    if (dialog != null) {
        ViewGroup parent = (ViewGroup) dialog.getParent();
        if (parent != null)
            parent.removeView(dialog);
    }
    try {
        dialog = inflater.inflate(R.layout.dlg_map, container, false);
    } catch (Exception e) {
        /* map is already there, just return view as it is */

    }

    return dialog;
}

@Override
public void onStart() {
    super.onStart();
    // Utility.Log("onStart");
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Utility.Log("onCreate");
    FragmentManager fm = getChildFragmentManager();
    mMapFragment = (SupportMapFragment) fm.findFragmentById(R.id.mapView);
    if (mMapFragment == null) {
        mMapFragment = SupportMapFragment.newInstance();
        fm.beginTransaction().replace(R.id.mapView, mMapFragment).commit();
    }
}

@Override
public void onActivityCreated(Bundle arg0) {
    super.onActivityCreated(arg0);

    init();
    loadMap();
    initMap();
    listner();

}

            GooglePlayServicesUtil.getErrorDialog(chkGooglePlayServices, getActivity(), 1122).show();
        } else {
            mMap = mMapFragment.getMap();
