为什么我的地图不起作用？

Question

嗨:)我有一些问题，包括我的Android应用程序中的谷歌地图。我一直在尝试一切，包括扩展MapActivity并将此行添加到我的项目清单<uses-library android:name="com.google.android.maps" />。我仍然得到同样的错误。

这是logcat的输出。

这是我到目前为止唯一的代码

public class Map extends MapActivity {
    MapView map_view;
    GoogleMap map;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout_map);

        MapsInitializer.initialize(this);

        map_view = (MapView) findViewById(R.id.map_view);
        map_view.onCreate(savedInstanceState);
        map = map_view.getMap();
        map.setMapType(GoogleMap.MAP_TYPE_SATELLITE);

代码似乎在此行崩溃：setContentView(R.layout.layout_map); 谢谢！
