I did checked many post and tried all solutions, but its not working. It seems that other menu item is not a problem, Only this location page gives an error.

fragment_location.xml

<?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">

<Spinner
    android:id="@+id/spinner1"
    android:layout_width="match_parent"
    android:layout_height="40dp"
    android:background="@color/white"
    android:spinnerMode="dropdown"/>

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="40dp"/>

</RelativeLayout>

LocationFragment.java

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

        view = inflater.inflate(R.layout.fragment_location, container, false);// this is the line 73
        SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);

    return view;
}

Answer 1

Try to remove your mapFragment on onDestroyView in LocationFragment.java.

@Override
public void onDestroyView() {
    super.onDestroyView();
    SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
    if (mapFragment != null)
        getChildFragmentManager().beginTransaction().remove(mapFragment).commitAllowingStateLoss();
}

Answer 2

I think the main reason is this you use name instead of class,

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

Try updating around this code base.

  FragmentManager fmanager = getSupportFragmentManager();
   Fragment fragment = fmanager.findFragmentById(R.id.map);
        SupportMapFragment supportmapfragment = (SupportMapFragment)fragment;
        GoogleMap supportMap = supportmapfragment.getMap()

You are using childSupportmanager , also this line view = inflater.inflate(R.layout.fragment_location, container, false); you never anchored your map view from it, example view.findViewVyId you never did that
