android - Get Current Location 0 in marshmallow where below 23 API its give exact current Location using fused Location

I got current Location in Below 23 devices but getting (0.0,0.0) latitude and Longitude in 23 emulator device.

EDIT Currently I am using Fused Location Provider for get Current Location

public class ContactUsFragment extends Fragment implements ConnectionCallbacks, OnConnectionFailedListener, LocationListener {
 @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.i("TAG", "OnCreate Called");
    locationManager = (LocationManager) getActivity()
            .getSystemService(Context.LOCATION_SERVICE);
    buildGoogleApiClient();


}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         final Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    view = inflater.inflate(R.layout.fragment_contact_us, container, false);

    Log.i("TAG", "OnCreateView Called");
    setComponants(view);  // **** Method For Set Componants Of Layout

This is Map Image on click of it I want to get current Location and pass it to Native Google Map app of device for navigate to target Location

 mapImage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.i("TAG", "On ImageView Click");


            if (Build.VERSION.SDK_INT >= 23) {

                if (checkPermission(Manifest.permission.ACCESS_FINE_LOCATION, getActivity().getApplicationContext(), getActivity())) {

                    if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
                        navigateToGoogleMap();
                    } else {
                        showSettingsAlert();
                    }
                } else {
                    requestPermission(Manifest.permission.ACCESS_FINE_LOCATION, PERMISSION_REQUEST_CODE, getActivity().getApplicationContext(), getActivity());
                }
            } else {

                if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
                    navigateToGoogleMap();
                } else {
                    showSettingsAlert();
                }

            }


        }


    });
    return view;
}

Below is code for get Current Location

private synchronized void buildGoogleApiClient() {
    Log.i("TAG", "Building GoogleApiClient");
    mGoogleApiClient = new GoogleApiClient.Builder(getActivity().getApplicationContext())
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API)
            .build();
    createLocationRequest();
}

private void createLocationRequest() {
    mLocationRequest = new LocationRequest();
    mLocationRequest.setInterval(UPDATE_INTERVAL);
    mLocationRequest.setFastestInterval(FASTEST_INTERVAL);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(mLocationRequest);
    //**************************
    builder.setAlwaysShow(true); //this is the key ingredient
    //**************************

}
@Override
public void onConnected(Bundle bundle) {

    Location mCurrentLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
    // Note that this can be NULL if last location isn't already known.
    if (mCurrentLocation != null) {
        // Print current location if not null
        Log.d("DEBUG", "current location: " + mCurrentLocation.toString());
        currentlatitude = mCurrentLocation.getLatitude();
        currentlongitude = mCurrentLocation.getLongitude();
    }
    // Begin polling for new location updates.
    startLocationUpdates();
}

private void startLocationUpdates() {

    LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,
            mLocationRequest, this);
}

private void stopLocationUpdates() {
    LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
}

@Override
public void onConnectionSuspended(int i) {
    if (i == CAUSE_SERVICE_DISCONNECTED) {
        Toast.makeText(getActivity().getApplicationContext(), "Disconnected. Please re-connect.", Toast.LENGTH_SHORT).show();
    } else if (i == CAUSE_NETWORK_LOST) {
        Toast.makeText(getActivity().getApplicationContext(), "Network lost. Please re-connect.", Toast.LENGTH_SHORT).show();
    }
    mGoogleApiClient.connect();
}

@Override
public void onLocationChanged(Location location) {
    String msg = "Updated Location: " +
            Double.toString(location.getLatitude()) + "," +
            Double.toString(location.getLongitude());
    Toast.makeText(getActivity().getApplicationContext(), msg, Toast.LENGTH_SHORT).show();

    currentlatitude = location.getLatitude();
    currentlongitude = location.getLongitude();
}

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {

}

*This code is Working Properly when I use in below API23 devices but when I try on marshmallow Device it give current Location 0.0,0.0 *
