Android - android.view.InflateException: Binary XML file line #8: Error inflating class fragment



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.



howtoreach.xml




xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">


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

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.
