googlemap lite mode in mapview is not working in marshmallow

=> I'm using following MapView in my layout:-

------------------------------------------------------------

android:id="@+id/map"
class="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="190dp"
android:layout_gravity="bottom"
android:layout_marginTop="5dp"
android:layout_marginBottom="10dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_below="@+id/ivLocation"
android:padding="1dp"
android:background="#D3D3D3"
map:liteMode="true"
/>
=> I have the following code in onCreateView() of fragment:-

MapsInitializer.initialize(this.getActivity());
mapView = (MapView) view.findViewById(R.id.map);
mapView.onCreate(savedInstanceState);
mapView.getMapAsync(this);
mapView.setClickable(false);

=> And i also have the following code in the fragment class :-

@Override
public void onPause() {
super.onPause();
mapView.onPause();
}

@Override
public void onDestroy() {
super.onDestroy();
mapView.onDestroy();
}

@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
mapView.onSaveInstanceState(outState);
}

@Override
public void onLowMemory() {
super.onLowMemory();
mapView.onLowMemory();
}

@Override
public void onResume() {
super.onResume();
mapView.onResume();
}

@Override
public void onDestroyView() {
super.onDestroyView();
}

@Override
public void onMapReady(GoogleMap googleMap) {
map = googleMap;
if (ActivityCompat.checkSelfPermission(getContext(), android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getContext(), android.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;
}
map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
LocationManager locationManager = (LocationManager) getContext().getSystemService(Context.LOCATION_SERVICE);
Location lastLocation = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
LatLng latLng = new LatLng(lastLocation.getLatitude(), lastLocation.getLongitude());
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, 16));
map.addMarker(new MarkerOptions().position(latLng).title("City Coordinator location at login").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_YELLOW)));
map.getUiSettings().setMapToolbarEnabled(false);
}

This code is working in moto e2 phone with lollipop android, but not working in moto g3 phone with marshmallow android. In marshmallow, map is not loading at all in googlemap lite mode. If i remove this attribute( map:liteMode="true") in mapview, map is loading but marker is not present.

what to pass as arguments for requestPermission(). What permissionType and requestCode should i pass.

It is working after enabling location permission for that app in phone settings.

in the code you have provided, I'm getting error in the following line, android studio is not able to resolve the symbol ACCESS_FINE_LOCATION.

requestPermission(Manifest.permission.ACCESS_FINE_LOCATION, LOCATION_REQUEST_CODE);
