I am developing an app using a NavigationDrawer
i.e. DrawerLayout
and navigating to different Fragments
. When I call a Map_Fragment_Page
the application crashes, but not the first time. For the first time it displays the Map
properly but after that when I navigate different fragments and again come to Map_Fragment_Page
then it crashes giving an error android.view.InflateException: Binary XML file line #8: Error inflating class fragment
I tried so many different solutions and I also also searched on Google
but still not getting the required solution. The problem is not yet fixed.

Answer
Yes.. I want Map inside a Fragment.
You should use a MapView
http://developer.android.com/reference/com/google/android/gms/maps/MapView.html
public class HowToReach extends Fragment {
MapView mapView;
GoogleMap map;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment2, container, false);
// Gets the MapView from the XML layout and creates it
try {
MapsInitializer.initialize(getActivity());
} catch (GooglePlayServicesNotAvailableException e) {
Log.e("Address Map", "Could not initialize google play", e);
}
switch (GooglePlayServicesUtil.isGooglePlayServicesAvailable(getActivity()) )
{
case ConnectionResult.SUCCESS:
Toast.makeText(getActivity(), "SUCCESS", Toast.LENGTH_SHORT).show();
mapView = (MapView) v.findViewById(R.id.map);
mapView.onCreate(savedInstanceState);
// Gets to GoogleMap from the MapView and does initialization stuff
if(mapView!=null)
{
map = mapView.getMap();
map.getUiSettings().setMyLocationButtonEnabled(false);
map.setMyLocationEnabled(true);
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(43.1, -87.9), 10);
map.animateCamera(cameraUpdate);
}
break;
case ConnectionResult.SERVICE_MISSING:
Toast.makeText(getActivity(), "SERVICE MISSING", Toast.LENGTH_SHORT).show();
break;
case ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED:
Toast.makeText(getActivity(), "UPDATE REQUIRED", Toast.LENGTH_SHORT).show();
break;
default: Toast.makeText(getActivity(), GooglePlayServicesUtil.isGooglePlayServicesAvailable(getActivity()), Toast.LENGTH_SHORT).show();
}
// Updates the location and zoom of the MapView
return v;
}
@Override
public void onResume() {
mapView.onResume();
super.onResume();
}
@Override
public void onDestroy() {
super.onDestroy();
mapView.onDestroy();
}
@Override
public void onLowMemory() {
super.onLowMemory();
mapView.onLowMemory();
}
}
fragment2.xml
android:layout_width="match_parent"
android:layout_height="match_parent">
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/map" />
Update:
https://developers.google.com/android/reference/com/google/android/gms/maps/MapView#public-constructors
getMap()
is deprecated. Use getMapAsync(OnMapReadyCallback)
instead. The callback method provides you with a GoogleMap instance guaranteed to be non-null and ready to be used.
