Add Google Maps API V2 in a fragment

Question

I'm trying to show the map from the Google Maps API V2 in fragment. I tried with the SupportMapFragment, but I can't get the expected output. Also I'm a beginner on this platform! What I really want is just a way to put a map from the Google Maps API V2 for Android in a fragment. Please share your ideas and references.

Thanks in Advance !

Here is the code,

public class YourFragment extends Fragment {
    // ...
  static final LatLng HAMBURG = new LatLng(53.558, 9.927);
          static final LatLng KIEL = new LatLng(53.551, 9.993);
          private GoogleMap map;

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View v = inflater.inflate(R.layout.yourlayout, null, false);

        map = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map))
            .getMap();

Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
                .title("Hamburg"));
            Marker kiel = map.addMarker(new MarkerOptions()
                .position(KIEL)
                .title("Kiel")
                .snippet("Kiel is cool")
                .icon(BitmapDescriptorFactory
                    .fromResource(R.drawable.ic_launcher)));

            // Move the camera instantly to hamburg with a zoom of 15.
            map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));

            // Zoom in, animating the camera.
            map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);

        //...

        return v;
    }

Your layout,

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment" />

</RelativeLayout>

Make some changes in your manifest file also.Like,

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.myapp.android.locationapi.maps"
    android:versionCode="1"

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

                <category android:name="android.intent.category.LAUNCHER" />

I'm trying to put the map in a Fragment here you're doing it in a Activity ! — Seïfane Idouchach, Jun 07 '13 at 07:11
Eclipse is giving me this error : "Cannot cast from Fragment to MapFragment" — Seïfane Idouchach, Jun 07 '13 at 07:19
In this case I can't because I'm using the Master/Flow details Sample and this Fragment is used in a FragmentActivity. — Seïfane Idouchach, Jun 07 '13 at 07:24
Also if I change from Fragment to FragmentActivity then a lot more of error are showing up ! — Seïfane Idouchach, Jun 07 '13 at 07:25
Thanks a lot it finnaly worked ! You should edit your layout code to make the fragment with this class ' class="com.google.android.gms.maps.SupportMapFragment"' — Seïfane Idouchach, Jun 07 '13 at 07:32
@SeïfaneIdouchach: please refer this http://stackoverflow.com/questions/16959083/android-map-v2-not-works-in-emulator-errors-are-occurred-in-log-cat/16959187#16959187 — Suraj, Jun 07 '13 at 07:54
App crashes at map = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)) .getMap();. I guess the getFragmentManager() return null. — Bagusflyer, Dec 04 '13 at 09:07
So, have you ever tried to add this fragment twice. It will crash at second time.. — Onuray Sahin, Dec 05 '13 at 22:12
Yes this crashes when you try and add it the second time. You need to add some code to onDestroyView() to clean things up. But I am not sure the proper way to clean it. Anyone??? — lostintranslation, Apr 07 '14 at 19:05

I've implemented this code before, when I upgrade play-service version to 4.3+ into android studio it crash every time like @PauloRoberto said in previous, other wise it work fine before in eclipse build. Have you any solutions for implementing GoogleMap into a fragment? — biswajitGhosh, Aug 17 '15 at 15:50
@biswajitGhosh any luck on adding a map to Fragment? Getting same crash as you — user1406716, Jan 20 '16 at 07:30
There is a call getChildFragmentManager(), so you should use that instead of getFragmentManager() when you are dealing with fragments inside of a fragment. — smiki, Feb 24 '16 at 13:06

have u implement mapView = (MapView) view.findViewById(R.id.mapView); mapView.onCreate(savedInstanceState); ?? or plz upload ur code — Vaishali Sutariya, Aug 11 '14 at 09:20
Yeah its fixed, i was doing it the wrong way i was putting it in a method which was not getting called :D Thanks for your help. Though i couldn't manage to put gmap api inside another fragment, i got a work around. — Sujal Mandal, Aug 11 '14 at 17:44

Update 10/24/2014 This is all wrong. You shouldn't have a fragment in a fragment. Rather you should extend the SupportMapFragment. See this stackoverflow post for some details: https://stackoverflow.com/a/19815266/568197

here is my onDestroyView()

public void onDestroyView() {
    super.onDestroyView();
    if (mMap != null) {
        getFragmentManager()
                .beginTransaction()
                .remove(getFragmentManager().findFragmentById(R.id.map))
                .commit();
    }
}

in addition to the answer above, I also had to put the following lines to my manifest

<!-- inside <aplication> tag -->    
<meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />

And I also changed the layout to use SupportMapFragment instead of MapFragment

<fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment" />

Use `SupportMapFragment` instead of `MapFragment` and use `getActivity()`

This is a basic example using SupportMapFragment:

public class MainActivity extends ActionBarActivity implements OnMapReadyCallback{
    
    private SupportMapFragment map;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);        
        map = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
        map.getMapAsync(this);//remember getMap() is deprecated!      
    }

    @Override
    public void onMapReady(GoogleMap map) {
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(
            new LatLng(47.17, 27.5699), 16));
        map.addMarker(new MarkerOptions()
            .icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_launcher))
            .anchor(0.0f, 1.0f) // Anchors the marker on the bottom left
            .position(new LatLng(47.17, 27.5699))); //Iasi, Romania
        map.setMyLocationEnabled(true);
    }
}

and change the reference in your layout:

<fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment" />

Isn't this using an Activity when the user asked for implementation in a Fragment? — FlameDra, Mar 09 '17 at 06:19
"Isn't this using an Activity when the user asked for implementation in a Fragment?" : Is that the reason for the -1?, remember **A Fragment is always contained inside an Activity**. — Jorgesys, Jul 25 '17 at 23:47

Here is my code.

Create project in google map concole and generate api key.

and then add dependency to build.gradle(app level).

compile 'com.google.android.gms:play-services-maps:10.2.1'
compile 'com.google.android.gms:play-services-location:10.2.1'
compile 'com.google.android.gms:play-services-places:10.2.1'

remember to add permissions in Android.manifest

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

For all those friends who are facing the problem:-

java.lang.NullPointerException: Attempt to invoke virtual method 'com.google.android.gms.maps.GoogleMap com.google.android.gms.maps.SupportMapFragment.getMap()

Please try integrate GoogleMap using code

FragmentManager fm = getChildFragmentManager();
googleMap = ((SupportMapFragment)fm.findFragmentById(R.id.googleMap)).getMap();

If you are using android studio create google mapsactivity its default map fragment and generate your map API KEY and do your stuff......

SupportMapFragment mapFragment = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map); mapFragment.getMapAsync(this);

and our override method

public void onMapReady(GoogleMap googleMap) {

   mMap = googleMap;
   LatLng map = new LatLng(lat, lon);
   mMap.addMarker(new MarkerOptions().position(map).title("your title"));
   mMap.animateCamera(CameraUpdateFactory.newLatLng(map));
   mMap.setMapType(GoogleMap.MAP_TYPE_NONE);

}

This example was build from the auto generated code from android studio, you dont need to change nothing in maps activity, only the context in the layout file to match your maps Activity

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:weightSum="1">

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="300dp"
tools:context="com.gearwell.app.gpsmaps02.Gpsenmapa"

/>

<LinearLayout
    android:id="@+id/layButtonH"
    android:layout_height="150dp"
    android:layout_marginTop="50dp"
    android:layout_width="fill_parent"
    android:gravity="center"
    android:layout_weight="0.15">
    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Obtener Ubicacion"
        android:id="@+id/btnLocation"

Using MapView within Fragment under Google Maps Android API v2.0

public class MapFragment extends Fragment {

    MapView m;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
            Bundle savedInstanceState) {
        // inflat and return the layout
        View v = inflater.inflate(R.layout.map_fragment, container, false);
        m = (MapView) v.findViewById(R.id.mapView);
        m.onCreate(savedInstanceState);

        return v;
    }

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

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

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

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