Display Google maps in tab using FragmentTabHost

问题

I'm trying to implement tabs for navigation in an Android app using this tutorial from Krishnabhadra

Tab1 -> Frag1 -> Frag2

Tab2 -> Frag3

Tab3 -> Frag4

Everything works fine with the scenario like this, but when I change Frag2 view to Google maps:

Navigate from Frag1 -> Frag3 or Frag4 -> Back to Frag1: works just fine

Navigate from Frag1 -> Frag2 (now is Google maps) -> Frag3 or Frag4 or back to Frag1: works just fine until I navigate back to Frag2 again then problem occurs

Everything is quiet the same as in the tutorial except the layout for the maps fragment

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <FrameLayout
        android:id="@+id/mapFrame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

        <fragment
            android:id="@+id/shopsMaps_map"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            class="com.google.android.gms.maps.SupportMapFragment" />

        <ImageButton
            android:id="@+id/myMapLocationButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom|left"
            android:layout_marginBottom="10dp"
            android:layout_marginLeft="10dp"
            android:background="@drawable/track_icon"
            android:contentDescription="My Location" />
    </FrameLayout>

</LinearLayout>
