谷歌地图V2不是沃金

Question

我正在使用谷歌地图v2，并得到了这个错误。

找不到从方法Maps.ag.an.a引用的类“Maps.af.k”

1F:41:29:EC:E8:07:3C:A9:F8:6E:EB:D2:7B:42:41:62:3A:36:CA:F2;com.example.routes

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

public class MainActivity extends FragmentActivity {
GoogleMap googleMap;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    SupportMapFragment fragment = new SupportMapFragment();
    getSupportFragmentManager().beginTransaction()
            .add(android.R.id.content, fragment).commit();
    ;

     googleMap = ((SupportMapFragment)    

  getSupportFragmentManager().findFragmentById(
                R.id.map)).getMap();
  }
}

但我还是犯了这个错误。

尝试扩展Activity而不是fragmentactivity：

  public class MainActivity extends Activity implements LocationListener{
LocationManager locationManager;
    private GoogleMap googleMap;
double lat=17.385044;
double long=78.486671;
 @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
    LocationManager service=(LocationManager)getSystemService(LOCATION_SERVICE);
    locationManager=(LocationManager)getSystemService(Context.LOCATION_SERVICE);
 Criteria criteria = new Criteria();
    provider = locationManager.getBestProvider(criteria, false);
   Location location = locationManager.getLastKnownLocation(provider);
  private void initilizeMap(){
if(googleMap==null){
 googleMap=((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();
    //check if map is created succesfully or not
    if(googleMap==null){
Toast.makeText(getApplicationContext(),"sorry unable to create map",1).show();
    }
 } 
MarkerOptions markerOptions=new MarkerOptions().position(new LatLng(lat,long));
markerOptions.icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_launcher));
CameraPosition cameraPosition=new CameraPosition.Builder().target(new LatLng(17.385044,     78.486671)).zoom(12).build();
 googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
 googleMap.setMyLocationEnabled(true);
 googleMap.setOnInfoWindowClickListener(null);
 }

  @Override
  protected void onResume(){
 super.onResume();
 initilizeMap();
   }
