Xamarin Android - Using FragmentTabHost in a Fragment

I have a navigation drawer app that I am using Fragments

. I am trying to create Fragment

one that uses tabs with FragmentTabHost

. The problem I am experiencing is that the content I am expecting in the tab is missing. It's just an empty tab.

Fragment

Android.Support.V4.App.Fragment

...

Here is my code:

class MyTabFragment : Fragment
{
    private FragmentTabHost mTabHost;

    public override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);

    }

    public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        mTabHost = new FragmentTabHost(Activity);
        mTabHost.Setup(Activity, ChildFragmentManager);
        mTabHost.AddTab(mTabHost.NewTabSpec("ATab").SetIndicator("ATab"), 
            Java.Lang.Class.FromType(typeof(MyCustomFragment)), null);
        return mTabHost;
    }

    public override void OnDestroyView()
    {
        base.OnDestroyView();
        mTabHost = null;
    }
}

      

        
        
        
      

    

Alternatively, I tried this:

    public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        return inflater.Inflate(Resource.Layout.fragment_tabhost, container, false);
    }

    public override void OnStart()
    {
        base.OnStart();
        mTabHost = View.FindViewById<FragmentTabHost>(Resource.Id.tabhost);
        mTabHost.Setup(Activity, ChildFragmentManager, Resource.Id.realtabcontent);
        mTabHost.AddTab(mTabHost.NewTabSpec("ATab").SetIndicator("ATab"), 
            Java.Lang.Class.FromType(typeof(MyCustomFragment)), null);
    }

      

        
        
        
      

    

XML:

<android.support.v4.app.FragmentTabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tabhost"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <TabWidget
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="0"
            android:orientation="horizontal" />

        <FrameLayout
            android:id="@+id/tabcontent"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:layout_weight="0" />

        <FrameLayout
            android:id="@+id/realtabcontent"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1" />

    </LinearLayout>

</android.support.v4.app.FragmentTabHost>

      

        
        
        
      

    

But in this case, I get a fatal exception. Here is the stack trace:
