I hooked up a button to show the second fragment and hide the first.

Problem: When i click the button to show the second mapfragment it will not show up but i lose control the the first fragment(cant move map, cant zoom). I am not sure what is going on here or if i am just missing something stupid again. I feel like the fragment is switching but the view is not refreshing.

public void onTabUnselected(Tab tab, FragmentTransaction ft) {
			Log.d(TAG, "onTabUnselected");
			if (mFragment != null) {
				// Detach the fragment, because another one is being attached
				ft.detach(mFragment);
			}
		}
