Fragments TabHost with Maps

Question

1. I have a StartActivity that extends FragmentActivity. The layout contains the calling for the fragment, <fragment class="bla.bla.bal.TabsFragment">

2. The TabsFragment contains the interaction between the fragments. All these works fine with different fragments.

3. Now I have another Activity that extend MapActivity. I would like to include this map and keep the TabHost still at the bottom of the view. Does anyone know how to do this?

I've checked Best way to implement tabs with lists, fragments and maps? and need fast help for Google Maps in fragments with compatibility android support libs for android but I still have troubles...
