Android SupportMapFragment inside Fragment

I'm trying to use SupportMapFragment inside a fragment. On the first launch, the map is display without any error.

But when I perform a transaction to another fragment, and after that return to the map, I have an error inflating fragment. But I don't have any error when I make en new instance of the fragment that contains the map.

Here is my layout :

<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"
    android:animateLayoutChanges="true"
    tools:context=".ui.HomeMapFragment">

    <fragment
        android:id="@+id/map"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@+id/footer"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"
        android:name="com.google.android.gms.maps.SupportMapFragment" />

    <FrameLayout
        android:id="@+id/footer"
        android:layout_height="110dp"
        android:layout_width="match_parent"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:background="@color/colorPrimary"/>

</RelativeLayout>

And I instanciate my SupportMapFragment in onCreateView like this :

 //Instantiate the map fragment
 mHolder.supportMapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);

And I call onMapReady in onActivityCreated :

if (mHolder.supportMapFragment != null)
     mHolder.supportMapFragment.getMapAsync(this);

Error log :

I know that it's not a good thing to hard code a fragment inside the layout of a fragment but I've already tried to perform this using a frameLayout but I get many more error

If you want to have map in fragment, you need to use MapView instead of SupportMapFragment How to use MapView in android using google map V2?
