Use this Code for Current Location:

googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
    // TODO: Consider calling
    //    ActivityCompat#requestPermissions
    // here to request the missing permissions, and then overriding
    //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
    //                                          int[] grantResults)
    // to handle the case where the user grants the permission. See the documentation
    // for ActivityCompat#requestPermissions for more details.
    return;
}
googleMap.setMyLocationEnabled(true);
googleMap.getUiSettings().setZoomControlsEnabled(false);
googleMap.getUiSettings().setMyLocationButtonEnabled(true);
googleMap.getUiSettings().setCompassEnabled(true);
googleMap.getUiSettings().setRotateGesturesEnabled(true);
googleMap.getUiSettings().setZoomGesturesEnabled(true);

if (locationManager == null) {
    locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
}
if (locationManager.getAllProviders().contains(LocationManager.GPS_PROVIDER)) {
    isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
    isNetworkProviderEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
    if (isGPSEnabled) {
        location = getLastLocationByProvider(locationManager, LocationManager.GPS_PROVIDER, getApplicationContext());
    } else if (isNetworkProviderEnabled) {
        location = getLastLocationByProvider(locationManager, LocationManager.NETWORK_PROVIDER, getApplicationContext());
    }

            locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 100000, 1, this);

                        if (Env.currentActivity instanceof LocationActivity) {
                            try {
                                gotoSettings();
                            } catch (Exception e) {
                                e.printStackTrace();
                            }

                }

        }

            latitude = location.getLatitude();
            longitude = location.getLongitude();

    }

    MarkerOptions marker = new MarkerOptions().position(
            new LatLng(latitude, longitude))

    marker.icon(BitmapDescriptorFactory
