Robolectric 3.0 InflateException with a map custom fragment

Question

I've seen many topic talking about this problem for example this answer concerning the SNAPSHOT version.

Is this still necessary because when I try to setup my activity I get :

    android.view.InflateException: XML file /Users/billey_b/android/android/app/build/intermediates/res/merged/targetARTVm/debug/layout/activity_preorder.xml line #-1 (sorry, not yet implemented): Error inflating class fragment

In the XML the fragment in question is declared :

          <fragment
            android:id="@+id/map"
            android:tag="mapfragment"
            class="com.me.widget.CustomSupportMapFragment"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

The CustomMapFragment extends SupportMapFragment

And my dependencies :

testCompile 'org.robolectric:robolectric:3.0'
testCompile "org.robolectric:shadows-play-services:3.0"
testCompile "org.robolectric:shadows-multidex:3.0"
testCompile 'org.robolectric:shadows-maps:3.0'
testCompile "org.robolectric:shadows-support-v4:3.0"

So what I've missed here ?
