如何僅在Google地圖中顯示某個地方？

我是剛剛開始的最近2天的android的初學者。我突然對它感興趣，因爲我參加了一個關於android的短期研討會。我目前正在開發自學習和瞄準一個應用程序，上面的Jellybean 4.1支持顯示地圖。我已經知道關於API等。現在地圖顯示，但我想要的目標是當我打開地圖時只顯示某個位置。例如，我將打開該應用程序（僅適用於韓國），GPS會自動啓用，並且會確定我目前在首爾。該地圖不會顯示其他國家，但只會設置爲韓國，並且只會縮放到首爾城。這裏是我有的代碼，但現在我有點失望，因爲我收到太多的錯誤，我不明白。如何僅在Google地圖中顯示某個地方？

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback { 

    private GoogleMap mMap; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_maps); 
     // Obtain the SupportMapFragment and get notified when the map is ready to be used. 
     SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager() 
       .findFragmentById(R.id.map); 
     mapFragment.getMapAsync(this); 

     Intent intent=new Intent("android.location.GPS_ENABLED_CHANGE"); 
     intent.putExtra("enabled", true); 
     sendBroadcast(intent); 
    } 

    @Override 
    public void onMapReady(GoogleMap googleMap) { 
     mMap = googleMap; 

     // Add a marker in Sydney and move the camera 
     LatLng seoul = new LatLng(8.2280, 124.2452); 
     mMap.addMarker(new MarkerOptions().position(seoul).title("Marker in seoul")); 
     mMap.moveCamera(CameraUpdateFactory.newLatLng(seoul)); 
     mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(8.2280,124.2452) , 14.0f)); 
    } 
}

我做了下面的答案，有一對夫婦更多的錯誤：

哪些錯誤？你可以發佈嗎？ –

使用此：

CameraPosition cameraPosition = new CameraPosition.Builder() 

    .target(MOUNTAIN_VIEW)  // Sets the center of the map to Mountain View 

    .zoom(17)     // Sets the zoom 

    .bearing(90)    // Sets the orientation of the camera to east 

    .tilt(30)     // Sets the tilt of the camera to 30 degrees 

    .build();     // Creates a CameraPosition from the builder 

map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));

這應有助於：

if (seoul!=null) { 

     mMarkerOptions = new MarkerOptions(); 
     mMarkerOptions.position(seoul); 
     mMarkerOptions.title(completeAddress); 
     mMap.addMarker(mMarkerOptions).showInfoWindow(); 
     mMap.moveCamera(CameraUpdateFactory.newLatLng(seoul)); 
     mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(seoul, 14.0f)); 
    }
