Here's my my_location.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
Here's my code:
public class MyLocation extends Fragment {
private GoogleMap googleMap;
Context mContext;
public MyLocation (){ mContext = getActivity(); };
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
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 included all the libraries and generated the API key
output is shown below
no error message is logged. what could possibly go wrong in displaying the map ?
Note : same code is working on another application with different API key ofcourse and map is displayed correctly.
IMPORTANT NOTE:The app was already published on google play store before adding the Maps SDK API,so is there any modifications that I should do considering that or its irrelative?
Go to console.google.com
And generate a new API key with package name(com.package.app) same as in your mobile app and SHA1.
Get the new API key, replace in the code. Uninstall the app and re-run.
Okey , so i am not using FragmentActivity, and this may not directly tell the solution.
But this code definitely works and shows map using android.support.v4.app.Fragment.
import android.support.v4.app.Fragment;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapView;
import com.google.android.gms.maps.MapsInitializer;
import com.google.android.gms.maps.OnMapReadyCallback;
public class OrderMapFrag extends Fragment implements OnMapReadyCallback{
private GoogleMap mGoogleMap;
private MapView mMapView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_order_map, container, false);
........
........
mMapView.onCreate(savedInstanceState);
mMapView.onResume();
try {
MapsInitializer.initialize(getActivity().getApplicationContext());
} catch (Exception e) {
e.printStackTrace();
}
mMapView.getMapAsync(this);
return view;
}
#Override
public void onMapReady(GoogleMap googleMap) {
mGoogleMap = googleMap;
//setting initial elements in map if required after this , as map got initialized properly
}
}
But I am not using exact same elements and permissions you use in Manifest. For me these are the used ones.
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<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"
android:value="MY API KEY"/>
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();
}
}

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 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.

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...

I m using google maps v2 and getting this error.
Could not find class 'maps.af.k', referenced from method maps.ag.an.a
I m following all the rules correctly. I have created SHA1 finger print and added it to ANdroid Key for apikey with projct name
1F:41:29:EC:E8:07:3C:A9:F8:6E:EB:D2:7B:42:41:62:3A:36:CA:F2;com.example.routes
Then in mainest file i m using
<fragment
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="#+id/map"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
i have also imported the googleplayservices and correctly added it to the project
My code is
public class MainActivity extends FragmentActivity {
GoogleMap googleMap;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SupportMapFragment fragment = new SupportMapFragment();
getSupportFragmentManager().beginTransaction()
.add(android.R.id.content, fragment).commit();
;
googleMap = ((SupportMapFragment)
getSupportFragmentManager().findFragmentById(
R.id.map)).getMap();
}
}
but still i m getting that error.
Try to extend Activity rather then FragmentActivity:
public class MainActivity extends Activity implements LocationListener{
LocationManager locationManager;
private GoogleMap googleMap;
double lat=17.385044;
double long=78.486671;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LocationManager service=(LocationManager)getSystemService(LOCATION_SERVICE);
locationManager=(LocationManager)getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
provider = locationManager.getBestProvider(criteria, false);
Location location = locationManager.getLastKnownLocation(provider);
private void initilizeMap(){
if(googleMap==null){
googleMap=((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();
//check if map is created succesfully or not
if(googleMap==null){
Toast.makeText(getApplicationContext(),"sorry unable to create map",1).show();
}
}
MarkerOptions markerOptions=new MarkerOptions().position(new LatLng(lat,long));
markerOptions.icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_launcher));
CameraPosition cameraPosition=new CameraPosition.Builder().target(new LatLng(17.385044, 78.486671)).zoom(12).build();
googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
googleMap.setMyLocationEnabled(true);
googleMap.setOnInfoWindowClickListener(null);
}
#Override
protected void onResume(){
super.onResume();
initilizeMap();
}
I had the same problem and my solution was to remove and add the googleplayservices again.
When you are using SupportMapFragment no need of extending FragmentActivity just extend the Activity See the below example code:
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
public class MainActivity extends Activity {
private GoogleMap map;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
Note: You have to add google play services library project as a reference to your project, your package name must be com.example.routes you have to add the map fragment in your xml layout not in the manifest.
Make following changes to your Manifest.xml
Add following permissions.
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
Add the OpenGL
<uses-feature
android:glEsVersion="0x00020000"
android:required="true"/>
Add the API key
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="API_KEY"/>
Example manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.package"
android:versionCode="1"
android:versionName="1.0" >

</RelativeLayout>
also include the following in your manifest file
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="enter your APIKEY" />
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
this code should be an element of application
then include this under the uses permission of your manifest file
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<!-- External storage for caching. -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<!-- My Location -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<!-- Maps API needs OpenGL ES 2.0. -->
<uses-feature
android:glEsVersion="0x00020000"
android:required="true" />
i hope this helps
