本文介绍了谷歌地图API第2不工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想建立使用谷歌地图API第2版的应用程序，但事情是，应用程序一直给我力量关闭虽然我也跟着所需的所有指令。
I am trying to build an application using Google Maps API v2 but the thing is, the application keeps giving me force closes although i followed all the required instructions.
下面是Android的一部分
Here is the android part
import android.support.v4.app.FragmentActivity;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
public class GPSonMap extends FragmentActivity{
MapView map;
MapController controller;
LocationManager locationManager;
LocationListener listener;
PendingIntent pendingIntent ;
Criteria criteria;
MapOverlay overlay;
@Override
public void onCreate(Bundle onsaved)
{
super.onCreate(onsaved);
setContentView(R.layout.map);
Log.d("", "entered");
map = (MapView)findViewById(R.id.mapView);
}
和这里是XML
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MapsActivity" >
<fragment
class="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/mapView"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>
这是我的清单

另外一个问题，我面对的是，当我尝试
进口com.google.android.gms.maps.MapFragment;
它提供了一个错误，它不承认一个包名称为 com.google.android.gms ，所以我不能甚至使用 GoogleMap的或 MapFragment 为例。
One other problem I face, is that when i try to
import com.google.android.gms.maps.MapFragment;
it gives an error that it doesnt recognise a package name to be com.google.android.gms so i cant even use the GoogleMapor MapFragment for example.
因此，没有人有任何解决这些问题的2？
So does anyone have any solution to those 2 problems?
推荐答案
presumably，您没有添加引用了谷歌播放服务库项目，您的应用程序的项目。请参见的谷歌播放服务SDK文档，特别是题为部分要设置一个项目使用谷歌Play业务的SDK。
Presumably, you have not added a reference to the Google Play Services library project to your app project. See the Google Play Services SDK documentation, specifically the section entitled "To set up a project to use the Google Play services SDK".
