我已经完成了所有Google Play服务，并已全部导入

public class Check extends Activity {
    static final LatLng HAMBURG = new LatLng(53.558, 9.927);
    static final LatLng KIEL = new LatLng(53.551, 9.993);
    private GoogleMap map;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
                .getMap();
        Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
                .title("Hamburg"));
        Marker kiel = map.addMarker(new MarkerOptions()
                .position(KIEL)
                .title("KIEL")
                .snippet("Kiel is cool")
                .icon(BitmapDescriptorFactory
                        .fromResource(R.drawable.ic_launcher)));

        // Move the camera instantly to hamburg with a zoom of 15:
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));

        // Zoom in with animation:
        map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
        setContentView(R.layout.map);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
}

您是否拥有Google Maps API密钥？您应该注册并获取密钥并按顺序将其放入您的应用程序中能够使用他们的Api。看到这个链接： https://developers.google.com/maps/documentation/android/start#get_an_android_certificate_and_the_google_maps_api_key

地图无效的Android应用程序，同时显示没有错误，
