открытие гугл карты на вкладке в андроиде не работает

Question

Я пытаюсь открыть приложение Google Map, которое я сделал на вкладке, но оно не работает, оно продолжает получать сообщение о принудительном закрытии, когда я его запускаю. Я создал основной файл активности [TabtestingActivity], в котором создаются вкладки [класс HelloGoogleActivity содержит код карты, и он отлично работает без вкладок]

public class TabstestingActivity extends TabActivity {
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Resources res = getResources();
    TabHost tabHost = getTabHost();  // The activity TabHost
    TabHost.TabSpec spec;  // Reusable TabSpec for each tab
    Intent intent;  // Reusable Intent for each tab

        intent = new Intent().setClass(this, HelloGoogleActivity.class);

    spec = tabHost.newTabSpec("tabOne");  
    spec.setContent(intent); 
    spec.setIndicator("Tab One",res.getDrawable(R.drawable.tabselect)); 
    tabHost.addTab(spec);
        tabHost.setCurrentTab(0);
    }
}

если я создаю класс, в котором есть только текст, он отлично работает с вкладками, но когда я добавляю класс карты, он перестает работать. Это мой main.xml:

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

<TabWidget
 android:id="@android:id/tabs"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content" />
<FrameLayout
 android:id="@android:id/tabcontent       
 android:layout_width="fill_parent"
 android:layout_height="fill_parent" >

 <RelativeLayout 
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:orientation="vertical"
            android:layout_width="fill_parent" 
            android:layout_height="fill_parent">

  <com.google.android.maps.MapView
    android:id="@+id/mapview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:clickable="true"
    android:apiKey="my key"
    android:layout_weight="1"/>
</RelativeLayout>
</FrameLayout> 

</LinearLayout>
</TabHost>

есть ли проблема с моим main.xml?

Это logcat:

Answer 1

Трассировка довольно четкая,

"10-26 00:47:10.207: ERROR/AndroidRuntime(303): Caused by: java.lang.IllegalArgumentException: MapViews can only be created inside instances of MapActivity."

Вы не можете использовать MapView вне MapActivity.
