这是我的主要课程

public class MyActivity extends FragmentActivity {
    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);
        //setContentView(R.layout.main);

        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, animating the camera.
        map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
    }

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


}

我在IntellijIdea 12上工作，我添加了android支持库和谷歌播放服务，但当我尝试运行我的应用程序模拟器“不幸的是，mapv2example已停止”我从谷歌获取地图版本2 api密钥也是我的错误日志

你是否在build.gradle中正确编译了google play服务...你可以按照android开发者网站上的步骤... http://developer.android.com/google/play-services/setup.html ...也许你将不得不使用gmaps api v3 ......

...问候!!
