GoogleMap object is null

GoogleMap object is null - android

I am trying to add marker on map. But initializeMap() return null.
What could be the issue?
ActivityPlace.java
public class ActivityPlace extends AppCompatActivity {
GoogleMap mMap;
LatLng latlng;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_place);
if (initializeMap() && checkServices()) {
latlng = new LatLng(latitude, longitude);
MarkerOptions options = new MarkerOptions().position(latlng);
Marker marker = mMap.addMarker(options);
CameraUpdate update = CameraUpdateFactory.newLatLngZoom(latlng, 12);
mMap.animateCamera(update);
mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
#Override
public void onMapClick(LatLng latLng) {
//Launch Map Page
}
});
}
}
/*

public boolean checkServices() {
int isAvailable = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if (isAvailable == ConnectionResult.SUCCESS){
return true;
}else if (GooglePlayServicesUtil.isUserRecoverableError(isAvailable)){
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(isAvailable, this, ERROR_DIALOG_REQUEST);
dialog.show();
}else {
Toast.makeText(this, "Cant connect to mapping service", Toast.LENGTH_SHORT).show();
}
return false;
}
/*

*/
private boolean initializeMap() {
if (mMap == null) {
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map_fragment);
mapFragment.getMapAsync(new OnMapReadyCallback() {
#Override

});
}
return (mMap != null);

getMapAsync is async call which will be running in background and your method will return value false only.
My suggestion is to perform other operations when onMapReady is called.
mapFragment.getMapAsync(new OnMapReadyCallback() {
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
latlng = new LatLng(latitude, longitude);
MarkerOptions options = new MarkerOptions().position(latlng);
Marker marker = mMap.addMarker(options);
CameraUpdate update = CameraUpdateFactory.newLatLngZoom(latlng, 12);
mMap.animateCamera(update);
mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
#Override
public void onMapClick(LatLng latLng) {
//Launch Map Page
}
});
}
});

call this before intitializing map .
GoogleApiClient mGoogleApiClient ;
synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
if (mGoogleApiClient != null) {
mGoogleApiClient.connect();
}
}

Try this. It really works.
GoogleApiClient mGoogleApiClient ;
synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
if (mGoogleApiClient != null) {
mGoogleApiClient.connect();
}
}

Google maps v2 not initializing in fragment

I want to show my current location using Google maps v2 from a fragment however the Google maps is not initializing on start up. When i run the application, it is nor crashing but the map is not showing my current location neither is it displaying anything. I have used this code on my activity and it is fully functional.
Below is my java code:
public class MapFragment extends Fragment implements LocationListener,GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener,OnMapReadyCallback {
SupportMapFragment mSupportMapFragment;
MapView mMapView;

if (mSupportMapFragment == null) {
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

fragmentTransaction.replace(R.id.mapwhere, mSupportMapFragment).commit();
}
if (mSupportMapFragment != null) {
mSupportMapFragment.getMapAsync(this);

first of all Chaeck permission in manifest
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
then check method for current location
private GoogleMap.OnMyLocationChangeListener myLocationChangeListener = new GoogleMap.OnMyLocationChangeListener() {
#Override
public void onMyLocationChange(Location location) {
LatLng loc = new LatLng(location.getLatitude(), location.getLongitude());
marker = map.addMarker(new MarkerOptions().position(loc));
if(map != null){
map.animateCamera(CameraUpdateFactory.newLatLngZoom(loc, 16.0f));
}
}
};
then use
mMap.setOnMyLocationChangeListener(myLocationChangeListener);
and be patience map take laoding time depend on you network speed
comment if any query

First check your permissions and your google api key in your manifest
Your xml layout must be something like this without any thing else:
. <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="match_parent"
tools:context="com.isg_biz.isg_tracking.MainActivity" />
You have to implement OnMapReadyCallback, then
your code should be something like this in onCreate() :
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
Do not to copy and past the same xml code literally you have to change (tools : .....) to same that exist in your xml
for documentation, java code & more Please read :
https://developers.google.com/maps/documentation/android-api/map-with-marker

Android Runtime permission don't accept ok, only deny

After fixing another connected problem, now i have this one: i can't click on 'Ok' in the dialog to handle location permission, only on deny.
If i granted permission in manual way (via settings) i have this in log:

Sorry if i wrote stupid things, it's three days i'm going crazy with maps and i edited the code a lot of time.My idea is when i click on the right/down button camera will moves on the user position.
I tried also this lib:
https://github.com/googlemaps/android-samples/blob/master/ApiDemos/app/src/main/java/com/example/mapdemo/PermissionUtils.java
but nothing is changed

}
});

first of all:-
mMap.getCameraPosition().target
above snipped code will give you center position of Google Map.
at the time of loading map do
googleMap.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {
#Override
public void onMapLoaded() {
Log.e("TAG", googleMap.getCameraPosition().target.toString());
}
});
for when map move:-
googleMap.setOnCameraChangeListener(new OnCameraChangeListener() {
#Override
public void onCameraChange(CameraPosition arg0) {
googleMap.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {
#Override
public void onMapLoaded() {
LatLng latLng= arg0.target;
Log.d("TAG", latLng.toString());
//Toast.makeText(this, latLng.toString(), Toast.LENGTH_LONG).show();
}
});
}
});
I hope it will helps you..!

How to get Google Maps object inside a Fragment

I am using fragments in my application and I am new for this. There is a fragment in which I want to display Google Map and want to get its object, for this I have a fragment in my XML and I want to inflate it in the Fragment itself. When I am trying to inflate the map view its showing me error for getSupportFragmentManager().
How do I get the map object then that is the main issue. My XML is like this :-
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="250dp"
class="com.google.android.gms.maps.SupportMapFragment" />
And my Fragment in which I want to get the Google Map object is like that :-
public class FindMyCar extends Fragment {
private TextView mTvFind;
private TextView mTvPark;
private EditText mEtParkHint;
private GoogleMap map;
#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.findmycar, null);
initViews(view);
Typeface type = Typeface.createFromAsset(getActivity().getResources().getAssets(),"Multicolore.otf");
mTvFind.setTypeface(type);
mTvPark.setTypeface(type);
mEtParkHint.setTypeface(type);
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
return view;
}
#Override
public void onDestroyView() {
super.onDestroyView();
}
#Override
public void onDestroy() {
super.onDestroy();
}
private void initViews(View view){
mTvPark = (TextView) view.findViewById(R.id.tvFindCarPark);
mTvFind = (TextView) view.findViewById(R.id.tvFindCar);
mEtParkHint = (EditText) view.findViewById(R.id.etParkHint);
}
Can someone help me to get the object for my map so that I can show current location and draw the marker there.
Any help would be appreciable.
Thanks in advance.

getMap() method is deprecated
getMap() method is deprecated but after the play-services 9.2it is removed, so better use getMapAsync(). You can still use getMap() only if you are not willing to update the play-services 9.2 for your app.
To use getMapAsync(), implement the OnMapReadyCallback interface on your activity or fragment:
For fragment:
public class MapFragment extends android.support.v4.app.Fragment
implements OnMapReadyCallback { /* ... */ }
Then, while initializing the map, use getMapAsync() instead of getMap():
//call this method in your onCreateMethod
private void initializeMap() {
if (mMap == null) {
SupportMapFragment mapFrag = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.fragment_map);
mapFrag.getMapAsync(this);
}
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
setUpMap();// do your map stuff here
}
For Activity:
public class MapActivity extends FragmentActivity
implements OnMapReadyCallback { }
Then, while initializing the map, use getMapAsync() instead of getMap():
//call this method in your onCreateMethod
private void initializeMap() {
if (mMap == null) {
SupportMapFragment mapFrag = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.fragment_map);
mapFrag.getMapAsync(this);
}
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
setUpMap();// do your map stuff here
}
Fragment in XML:
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
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="match_parent"/>

Try this
GoogleMap map = ((SupportMapFragment) getFragmentManager()
.findFragmentById(R.id.map)).getMap();
and in your xml
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />

Try this it works for me

public class MapActivity extends FragmentActivity
implements OnMapReadyCallback { }
Then, while initializing the map, use getMapAsync() instead of getMap():
//call this method in your onCreateMethod
private void initializeMap() {
if (mMap == null) {
SupportMapFragment mapFrag = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.fragment_map);
mapFrag.getMapAsync(this);
}
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
}
You can use this to making map but it will return map object is null because you don't find solution with getMapAsync to create a new object mMap. It only background task with return null

mapFragment.getMapAsync(googleMap -> {

});

Revised code:
Your xml file-

android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Your java file (only relevant code)-
View view = null, mapView = null;
private GoogleMap mMap;
view = inflater.inflate(R.layout.findmycar, container,false);
FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
SupportMapFragment supportMapFragment = (SupportMapFragment) fragmentManager

mMap = supportMapFragment.getMap();
mapView = (View) view.findViewById(R.id.map);

Add Google Maps API V2 in a fragment

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"

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

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" />

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

Hope this will help you :-)

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" />

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();

I've the same issue , I use this code but I still get this error :
unable to instantiate fragment com.google.android.gsm.SupportMapFragment: make sure class name exists ,is public, and has empty construct or that is public
I solved it from here : How to put Google Maps V2 on a Fragment Using ViewPager

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"

</LinearLayout>
</LinearLayout>

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();
