MapFragment inside Fragment is not loading properly on second time opening of the fragment
I have a mapFragment inside a fragment along with other views, When i am opening the fragment for first time, its working normal, but reopening the fragment leads to a blank (White) screen..
Does anybody have the same problem? or anyone knows how to solve this.. Kindly help
public class CostEstimationFragment extends Fragment implements OnMapReadyCallback{
private GoogleMap mMap;
MapFragment mapFragment;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (rootView != null) {
ViewGroup parent = (ViewGroup) rootView.getParent();
if (parent != null)
parent.removeView(rootView);
}
try {
if(savedInstanceState==null){
rootView = inflater.inflate(R.layout.abc_layout, container,
false);
}
} catch (InflateException e) {
e.printStackTrace();
}
if(mMap==null)
mMap = getMapFragment().getMap();
mMap.clear();
}
XML of the respective class abc_layout.xml
<ScrollView>
<RelativeLayout>
<ListView/>
<LinearLayout
android:id="@+id/mapviewLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="50dp"
android:orientation="vertical"
android:layout_below="@+id/estimateLayout"
android:padding="10dp"
android:background="@color/white"
android:elevation="2dp">
<fragment
android:id="@+id/map"
class="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="300dp"/>
</LinearLayout>
<RelativeLayout/>
<ScrollView/>
Update-1
After reopening the Fragment i am getting below errors

I am using NavigationDrawer to do fragment transaction, So from onItemClickListerner of the BaseActivity i am calling this fragment,
if(title.equalsIgnoreCase("COSTESTIMATION")) {
fragment=new CostEstimationFragment();
}
if (fragment != null) {
FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
Fragment f = getFragmentManager().findFragmentById(
R.id.frame_container);
// fm.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
ft = fm.beginTransaction();
if (f != null) {
ft.hide(f);
}
ft.add(R.id.frame_container, fragment);
ft.addToBackStack(null);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
ft.commit();
UPDATE-2 added
if(fragment instanceof CostEstimationFragment){
ft.replace(R.id.frame_container, fragment);
}
i need to keep track of all other fragments opened to give a proper navigation to the app, so i just changed ft.replace(R.id.frame_container, fragment); for this fragment..
Now getting below errors in LogCat

I have done this way:
Always remove MapFragment on onDestroyView() to prevent InflateException.
onCreateView
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState){
if (view != null) {
ViewGroup parent = (ViewGroup) view.getParent();
if (parent != null)
parent.removeView(view);
}
try
{
view = inflater.inflate(R.layout.fragment_map_layout,null);
MapFragment mapFragment = (MapFragment) getActivity().getFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}catch (InflateException e) {
/* map is already there, just return view as it is */
}
return view;
}
onDestroyView
@Override
public void onDestroyView() {
super.onDestroyView();
MapFragment mapFragment = (MapFragment) getActivity().getFragmentManager()
.findFragmentById(R.id.map);
if (mapFragment != null){
getActivity().getFragmentManager().beginTransaction().remove(mapFragment).commit();
}
}
Hope this would help you.

implement OnMapReadyCallback interface in your fragment then Edit your code like below
if(mMap==null){
getMapFragment().getMapAsync(this);
//remove mMap.clear();
}
@Override
protected void onStart() {
super.onStart();
if(mMap==null){
getMapFragment().getMapAsync(this);
}
}
@Override
public void onMapReady(GoogleMap map) {
mMap=map;
}
And Also change this line:
ft.add(R.id.frame_container, fragment);
to
ft.replace(R.id.frame_container, fragment);
