Google Maps looks like an image

I have two Google Maps in my application, which I have implemented in the same way. One is working and one is not. The latter looks like an image and I can't interact with it. I can add markers and move the camera, but the info window doesn't show when I click the marker I can't move it, zoom in and zoom out. It looks like an image, a preview.
Here is the code:
public class MapFragment extends Fragment implements OnMapReadyCallback{
private GoogleMap mMap;
private static Double latitude;
private static Double longitude;
private static String title;
public static MapFragment newInstance(Double mLatitude, Double mLongitude, String mTitle) {
latitude=mLatitude;
longitude=mLongitude;
title=mTitle;
MapFragment fragment = new MapFragment();
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_map, container, false);
SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager()
.findFragmentById(R.id.map_details);
mapFragment.getMapAsync(this);
return view;
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.getUiSettings().setAllGesturesEnabled(true);
mMap.getUiSettings().setMapToolbarEnabled(false);
mMap.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory.fromResource(R.drawable.location_icon))
.position(new LatLng(latitude, longitude))
.title(title));
CameraPosition cameraPosition = new CameraPosition.Builder().target(new LatLng(latitude,longitude)).zoom(12f).build();
CameraUpdate cameraUpdate = CameraUpdateFactory.newCameraPosition(cameraPosition);
mMap.moveCamera(cameraUpdate);
}
public interface OnMapFragmentInteractionListener {
void onMapFragmentInteraction(Uri uri);
}
#Override
public void onResume() {
super.onResume();
}
#Override
public void onPause() {
super.onPause();
}
#Override
public void onDestroy() {
super.onDestroy();
}
#Override
public void onLowMemory() {
super.onLowMemory();
}
}

You should take a look at XML. There is liteMode and when it's set to true it does exactly what you are describing.
<com.google.android.gms.maps.MapView
android:id="#+id/row_map"
android:layout_width="match_parent"
android:layout_height="match_parent"
map:liteMode="true"
map:mapType="none" />
Here look at documentation

I'm just guessing but in code that you posted i see one mistake. To be sure you have to check your imports in the place when you try to use your MapFragment. As I said I guess that in one place it's imported from google pacage and another one from your class. The problem is that the MapFragment that you post here isn't a google MapFragment because you extants it from simple Fragment. To be sure rename your own MapFragment to CustomMapFragment and try to extands from MapFragment or just use it without customize.

Your code listing is missing the class declaration.
I guess you forgot to extend Activity.
You should reformat and expand your listing.

Cannot resolve onCreate or getMapAsync

I have two errors in my code .. the following lines have the errors. Cannot resolve onCreate() method and getMapAsync(). I have done invalidate caches and restart but it didn't help. Please help me solve this issue.
mapView.onCreate(savedInstanceState);
map = mapView.getMapAsync();
public class PlacesMapActivity extends Fragment implements OnMapReadyCallback {
private MapView mapView;
private GoogleMap map;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.map_places, container, false);
// Gets the MapView from the XML layout and creates it
mapView = (MapView) v.findViewById(R.id.map);
mapView.onCreate(savedInstanceState);
// Gets to GoogleMap from the MapView and does initialization stuff
map = mapView.getMapAsync();
map.getUiSettings().setMyLocationButtonEnabled(false);
map.setMyLocationEnabled(true);
// Needs to call MapsInitializer before doing any CameraUpdateFactory calls
try {
MapsInitializer.initialize(this.getActivity());
} catch (GooglePlayServicesNotAvailableException e) {
e.printStackTrace();
}
// Updates the location and zoom of the MapView
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(43.1, -87.9), 10);
map.animateCamera(cameraUpdate);
return v;
}
#Override
public void onMapReady(GoogleMap googleMap) {
}
}

Do not return anything: map = mapView.getMapAsync();
use:
mapView.getMapAsync(this);
then inside onMapReady() get the Map object
#Override
public void onMapReady(GoogleMap googleMap) {
map= googleMap;
}

How can I fetch google map with current location?

I tried to fetch a google map with current location but I got this error
FATAL EXCEPTION: main java.lang.NullPointerException
in
map= ((SupportMapFragment) getActivity().getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
java code
public class MapFragment extends Fragment{
private TextView locationText;
private TextView addressText;
private GoogleMap map;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootview = inflater.inflate(R.layout.fragment_map, container, false);
locationText = (TextView) rootview.findViewById(R.id.location);
addressText = (TextView) rootview.findViewById(R.id.address);
//replace GOOGLE MAP fragment in this Activity
return rootview;
}
public void onMapReady(GoogleMap map) {
//make the call here. it will be called once the map is ready
replaceMapFragment();
}
private void replaceMapFragment() {
map= ((SupportMapFragment) getActivity().getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
// Enable Zoom
map.getUiSettings().setZoomGesturesEnabled(true);
//set Map TYPE
map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
//enable Current location Button
map.setMyLocationEnabled(true);
//set "listener" for changing my location
map.setOnMyLocationChangeListener(myLocationChangeListener());
}
private GoogleMap.OnMyLocationChangeListener myLocationChangeListener() {
return new GoogleMap.OnMyLocationChangeListener() {
#Override
public void onMyLocationChange(Location location) {
LatLng loc = new LatLng(location.getLatitude(), location.getLongitude());
double longitude = location.getLongitude();
double latitude = location.getLatitude();
Marker marker;
marker = map.addMarker(new MarkerOptions().position(loc));
map.animateCamera(CameraUpdateFactory.newLatLngZoom(loc, 16.0f));
locationText.setText("You are at [" + longitude + " ; " + latitude + " ]");
//get current address by invoke an AsyncTask object
//new GetAddressTask(getActivity()).execute(String.valueOf(latitude), String.valueOf(longitude));
}
};
}
}

This may happened because the map is not ready at the moment.
#Override
public void onMapReady(GoogleMap googleMap) {
//make the call here. it will be called once the map is ready
replaceMapFragment();
}

In response to your comment on Kasun's answer, to display the current location marker on the map, call:
googleMap.setMyLocationEnabled(true);
Edit
import com.google.android.gms.maps.SupportMapFragment;
public class MapFragment extends SupportMapFragment
implements OnMapReadyCallback {
#Override
public void onCreate(Bundle inState) {
super.onCreate(inState);
// start a task for connecting to the map
// onMapReady() will be called when it is complete
getMapAsync(this);
}
#Override
public void onMapReady(GoogleMap googleMap) {
map = googleMap
// Enable Zoom
map.getUiSettings().setZoomGesturesEnabled(true);
//set Map TYPE
map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
//enable Current location Button
map.setMyLocationEnabled(true);
//set "listener" for changing my location
map.setOnMyLocationChangeListener(myLocationChangeListener());
}
}

Hi there, inside my initializeMap() , googleMap = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap(); keeps on saying that Cannot cast from Fragment to SupportMapFragment . I am not sure what is happening .
Thanks in advance

Change;
googleMap = ((SupportMapFragment) getFragmentManager().
findFragmentById(R.id.map)).getMap();
with this;
googleMap = ((SupportMapFragment) getSupportFragmentManager().
findFragmentById(R.id.map)).getMap();
Note that getSupportFragmentManager is from android.support.v4.app.FragmentActivity.
Good luck.

You need to use android.support.v7.app.Fragment;
And need to use getSupportFragmentManager
Basically you need v7 library

Check your activity layout. The fragment with map must have the following attribute name="com.google.android.gms.maps.SupportMapFragment" to indicate which fragment class you use.
