Question

我正在我的应用程序中集成谷歌地图。当我在模拟器上编译和朗读我的应用程序时，它显示我黑屏。我添加了所需的权限并在清单中添加了user-library标记，但它仍显示黑屏。这是我的代码

public class ActivityLiveMap extends MapActivity {
    private LocationManager locationManager;
    private Location location;
    private List<Overlay> overlayList;
    private GeoPoint mapPoint;
    private MapController controller;
    private MapView map;

    @Override
    protected void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.activity_map);
        init();
    }

    private void init() {
        map = (MapView) findViewById(R.id.map);
        map.setBuiltInZoomControls(true);
        map.setSatellite(true);
    }

    @Override
    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }
}

的manifest.xml
