Android application crashes on trying to inflate map layout on some devices but works fine on latest devices

This is my layout file:
My xml file which contains the map layout
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical" 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"
android:name="com.google.android.gms.maps.SupportMapFragment">
</fragment>
</FrameLayout>
My FragmentClass
public class RouteFragment extends Fragment {
GoogleMap map;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.map_layout,container,false);
// Getting reference to SupportMapFragment of the activity_main
SupportMapFragment fm = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
// Getting Map for the SupportMapFragment
map = fm.getMap();
MarkerOptions options = new MarkerOptions();
// Setting the position of the marker
options.position(MainActivity.lng1);
options.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN));
map.addMarker(options);
options.position(MainActivity.lng2);
map.addMarker(options);
map.moveCamera(CameraUpdateFactory.newLatLng(MainActivity.lng1));
map.animateCamera(CameraUpdateFactory.zoomTo(8));
if(getArguments().getInt("Driving")==1)
map.addPolyline(MainActivity.lineOptions);
else {
Polyline line = map.addPolyline(new PolylineOptions()
.add(MainActivity.lng1, MainActivity.lng2)
.width(5)
.color(Color.RED));
}
return v;
}
}
Here is the exception:
FATAL EXCEPTION: main
android.view.InflateException: Binary XML file line #8: Error inflating class fragment

Manifest file:
I have requested the desired permissions and defined the uses-library for incroporating maps in the application.
<uses-library android:name="com.google.android.maps"/>

GoogleMap throwing null pointer on getMap();

I am having a FragmentActivity, where I have successfully implemented a Google Map through my XML with this code:
<fragment
android:id="#+id/googleMap"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
However, if I try to initialize the map to find a persons location with this code:
GoogleMap googleMap;
googleMap = ((SupportMapFragment)(getSupportFragmentManager().findFragmentById(R.id.googleMap))).getMap();
It is throwing a null pointer exception, as I have understood from other questions regarding this error, it shouldn't be a problem initializing the map when it is created in the XML file. And yes I have used
setContentView(R.layout.map);
Before I initialize the map.

You use the Support Fragment So in your XML File Add
this Line In Fragment
class="com.google.android.gms.maps.SupportMapFragment"
like belove.
<fragment
android:id="#+id/googleMap"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"
/>
and Put This
googleMap = ((MapFragment) getFragmentManager().findFragmentById(
R.id.googleMap)).getMap();

The error is due to incorrect variable initialization try to change your code as shown below,thanks
private GoogleMap gMap;
MapFragment googleMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map_search);
googleMap= (MapFragment) getFragmentManager().findFragmentById(
R.id.googleMap);
gMap= googleMap.getMap();

In you xml you are using MapFragment.Change it -
<fragment
android:id="#+id/mapfragment"
android:layout_width="wrap_content"
android:layout_height="200dp"
android:layout_alignParentTop="true"
android:layout_gravity="center_horizontal"
class="com.google.android.gms.maps.SupportMapFragment" />
java -
googleMap = ((SupportMapFragment)getActivity().getSupportFragmentManager().findFragmentById(R.id.mapfragment)).getMap();

Android fail to load google map in fragment

I'm trying to use google map in fragment, but I meet a problem I don't understand.
I don't arrive to load the map in this line :
gMap = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
This line seems to return always null...
I tried to use MapFragment inseatd of SupportMapFragment, but it's not possible.
How to resolve it ?
To explain why i want to show it in a fragment, it's because i'm using a navigationdrawer, and one of my item needs to show the map.
thx,
EDIT : My xml :
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"/>

I think you should call with getsupportFragmentManager not with getFragmentManager otherwise it will return null always

If you are using SupportMapFragment, you need to change your layout!
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.SupportMapFragment"/>
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" />

I dont think it is possible as google map contains a < fragment> tag. See here why:
Note: You cannot inflate a layout into a fragment when that layout includes a . Nested fragments are only supported when added to a fragment dynamically.
Some people in SO however managed to show map in a fragment, but the solution was hacky.

Map Fragment Class doesnt infalte! Getting InflateException

I am having trouble with my android app.
I am trying to switch between two tabs which one of them should show a Map.
but the thread is exiting with uncaught exception.
When i debug i get this:
Binary XML file line #7: Error inflating class
com.google.android.gms.maps.MapView
I looked at every possible google search result but I coudlnt find the answer.
this is my mapclass
public class MapFragment extends Fragment {
MapView mapView;
GoogleMap map;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.mapview_tab, 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);
MapsInitializer.initialize(this.getActivity());
// Updates the location and zoom of the MapView
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(47.223065, 8.816511), 10);
map.animateCamera(cameraUpdate);
return v;
}
}
this is my xml file mapview_tab
<?xml version="1.0" encoding="utf-8"?>
<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" >
<com.google.android.gms.maps.MapView android:id="#+id/mapview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
and this dependency i added to the pom.xml file
<dependency>
<groupId>com.google.android.gms</groupId>
<artifactId>google-play-services</artifactId>
<version>16.0.0</version>
<scope>provided</scope>
</dependency>
and here are some important code writings out of my manifest:
<permission android:name="com.example.permission.MAPS_RECEIVE"
android:protectionLevel="signature"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-feature
android:glEsVersion="0x00020000"
android:required="true" >
</uses-feature>
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="dsvfdfsAdsfasdfcvdasVGJfsDSSDzcfdASWD"/>
<uses-library android:name="com.google.android.maps"/>
the googleplaylibraray jar file is a "non-runtime maven dependenciy"
I HOPE SOMEONE CAN HELP ME OUT!!

after clicking on the MAP TAB this is the last I get, then my phones freezes.

Post device version also it may be due to extends fragment class, if you are using devices for testing with lower version you have extend
public class MapFragment extends
android.support.v4.app.Fragment

check this link https://developers.google.com/maps/documentation/android/start#getting_the_google_maps_android_api_v2
---guidlines by google
way to go:--> use mapfragmet instead of mapview....
update
For Map class
public class MapFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.mapview_tab, container, false);
return v;
}
}

Accessing dynamically added google map fragment in framelayout

I have dynamically added my google map fragment in framelayout. Now I want to put markers and do other stuff with google map. but i am not able to access that through get fragment manager. The code shows no error but when it executes it returns null pointer exception.
I thinks its logical error. Something to do with type casting. plz help

I got answer on my own.
So it was really silly mistake.. after 6 hours i found that the error was on this line
googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.mapView)).getMap();
which was getting its parent view instead of child so replaced it with this line
googleMap = ((MapFragment) getChildFragmentManager().findFragmentById(R.id.mapView)).getMap();
and everything is fine :).
