I am using google map in a fragment and getting null when calling getMap(), this is my code:
In my MapViewFragment
private GoogleMap mGoogleMap;
I am getting null at this line, in onCreate() method...
mGoogleMap = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
In fragment_map_view file
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
The getMap method is deprecated. You should use getMapAsync:
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
#Override
protected void onCreate(Bundle savedInstanceState) {
// ...
((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMapAsync(this);
}
#Override
public void onMapReady(final GoogleMap googleMap) {
mGoogleMap = googleMap;
// Do something with your map
}
}
did you add the permissions and google API key ?
here is my code from project call this function in OnCreate()
private void CheckGoogleMap()
{
try {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().
findFragmentById(R.id.map)).getMap();
}
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
}
catch (Exception e) {
e.printStackTrace();
}
}
in XML file
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment"
android:layout_alignParentTop="true"

before closing of application TAG in Manifest file add this

android:value="YOUR API KEY" />
in Gradle add
compile 'com.google.android.gms:play-services:8.1.0'
I got the reason for it, I think I should post for future readers......
Actually as I GoogleMap was called in a fragment so, in the line..
mGoogleMap = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
instead of
getFragmentManager(), getSupportFragmentManager() should be used in fragments.
Corrected one-
mGoogleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

I'm trying to get my current location on google map but it's giving me a blank map.
this is my fragment
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback, LocationSource.OnLocationChangedListener, GoogleMap.OnMapClickListener {
private GoogleMap mMap;
private LatLng userLocation;
private GoogleApiClient mGoogleApiClient;
private Location mLastLocation;
public LocationManager mLocationManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
}
#Override
public void onLocationChanged(Location location) {
userLocation = new LatLng(location.getAltitude(), location.getLongitude());
Toast.makeText(this, "found you...", Toast.LENGTH_SHORT).show();
MarkerOptions markerOptions= new MarkerOptions();
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(userLocation, 10));
mMap.addMarker(new MarkerOptions().position(userLocation).title("you are here"));
}
#Override
public void onMapClick(LatLng latLng) {
}
}
then that's my manifest

I am trying over a week to setup my Google Map v2. but its not working for me.I tried answers from questions related to it but no use.i couldn't track the exact problem.please help.

This is my error log

you need to extend FragmentActivity/AppCompatActivity if you are using SupportMapFragment.
public class Map extends FragmentActivity/AppCompatActivity {
And
FragmentManager myFragmentManager = getSupportFragmentManager();
SupportMapFragment mySupportMapFragment = (SupportMapFragment)myFragmentManager.findFragmentById(R.id.map);
googleMap = mySupportMapFragment.getMap();
You can check Android Map V2
Try this
googleMap = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
Try this...

Here's my code:
public class MyLocation extends Fragment {

View root = inflater.inflate(R.layout.my_location, container, false);
googleMap = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
}
}
Unfortunately, it displays NPE at the line
googleMap = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
What did I do wrong?
In case, parts of my manifest

Solved my problem with the link given in the accepted answer! Here's what I did:
I just changed
googleMap = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
to
googleMap = ((SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map)).getMap();
Your issue is same with link1 link2 link3
Please do some search before ask a question.
The issue is because it takes time for google map to load ( if you're using inside a fragment, you can expect this load time to be huge) and when you try to access map before it is being loaded, you'll get NullPointerException saying map reference went null. You should wait for the map to load first and then you should access the map views. You have pre-defined callback for that and here is how you should use it.
supportMapFragment.getMapAsync(new OnMapReadyCallback() {
#Override
public void onMapReady(GoogleMap map) {
googleMap = map; }
});
i can show plain guide in inside part i have to add marker to specific geolocation
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="100dp"
android:name="com.google.android.gms.maps.SupportMapFragment"
/>
I don't did anything in java code however i extended my class with Fragment
Don't forget to add google-play-service-lib as a library project and
it should sharing the same workspace of your project
Java code
public class SomeFragment extends Fragment {
MapView mapView;
GoogleMap map;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.some_layout, container, false);
// Gets the MapView from the XML layout and creates it
mapView = (MapView) v.findViewById(R.id.mapview);
mapView.onCreate(savedInstanceState);
// Gets to GoogleMap from the MapView and does initialization stuff
map = mapView.getMap();
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

mapView.onResume();
super.onResume();
}

Edit: After your edit new question arise.
After initializing map check if it is not null from official documentation
if(map != null)
{
Marker marker = map.addMarker(new MarkerOptions()
.position(new LatLng(37.7750, 122.4183))
.title("San Francisco")
.snippet("Population: 776733"));
}
In your layout, replace your code with this one :
<RelativeLayout
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="100dp">
</RelativeLayout>
and in your code :
private SupportMapFragment supportMapFragment;
private GoogleMap map;
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
FragmentManager fm = getChildFragmentManager();
supportMapFragment = (SupportMapFragment) fm.findFragmentById(R.id.map);
if (supportMapFragment == null) {
supportMapFragment = SupportMapFragment.newInstance();
fm.beginTransaction().replace(R.id.map, supportMapFragment).commit();
}
}
#Override
public void onResume() {
super.onResume();
...
map = supportMapFragment.getMap();
...
}

Old MapView has been depreciated. You can't create a new Map key for publishing your app.
You have to use new Google Maps for Android v2 API. Here's a link to the documents and example.
https://developers.google.com/maps/documentation/android/start
make sure Google Repository && Google play Services is up to Date
add below to Project level Gradle
classpath 'com.google.gms:google-services:3.0.0'
and below two statements to App Level Gradle
compile 'com.google.android.gms:play-services-location:11.0.1'//for location
compile 'com.google.android.gms:play-services-maps:11.0.1'//for maps
compile 'com.google.android.gms:play-services-places:11.0.1'//for places
And add permission in Manifest
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
add below statment in tag
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
<meta-data
android:name="com.google.android.geo.API_KEY"

I could do this with the Google Map Activity bundled with Android Studio 1.2.1.1. I created a Google Maps Activity and followed the instructions as below:
Created the API Key following the instructions in google_maps_api.xml
To get one, follow this link, follow the directions and press "Create" at the end:
https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend&keyType=CLIENT_SIDE_ANDROID&r=XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY%3Bnpackagename
You can also add your credentials to an existing key, using this line:
XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY:XY;newmapscreen.avapps.nbapl.com.newmapscreen
Once you have your key (it starts with "AIza"), replace the "google_maps_key"
string in this file.
-->
<string name="google_maps_key" translatable="false" templateMergeStrategy="preserve">
AIzaXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
</string>
After that, I ensured all the dependencies are there in Android Manifest, build.gradle. See this answer for details.
In your MapActivity.java, you can add additional markers, and use the Android Google Maps API V2 features to enhance your map.
(replace XY:XY ...with whats in your google_maps_api.xml)
