Answer 2

Globals

private GoogleMap googleMap; 

Dans onCreate

try{ 
     _SetMap(); 
}catch(Exception e){ 
    e.printStackTrace(); 
} 

oncreate A l'extérieur, faire une nouvelle méthode _SetMap

private void _SetMap() { 
    if (googleMap == null) 
     googleMap = ((MapFragment) getFragmentManager().findFragmentById(
       R.id.map)).getMap(); 
    googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
} 
} 

Xml

<?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" 
android:orientation="vertical"> 

<fragment 
     android:id="@+id/map" 
     android:name="com.google.android.gms.maps.MapFragment" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"/> 


</LinearLayout> 

Dans le fichier manifeste en dehors étiquette d'application définissent

<permission 
    android:name="YourPackageName.permission.MAPS_RECEIVE" 
    android:protectionLevel="signature" /> 
    <uses-permission android:name="YourPackageName.permission.MAPS_RECEIVE" />

    <uses-feature

et dans la balise d'application manifeste définissent
