我正在尝试使用 Google Maps API v2 构建一个应用程序,但问题是,尽管我遵循了所有必需的说明,但该应用程序不断给我强制关闭。
这是安卓部分
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);
}
这是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

我面临的另一个问题是,当我尝试
import com.google.android.gms.maps.MapFragment;
它时,它会给出一个错误,它无法识别包名称,com.google.android.gms
所以我什至不能使用GoogleMap
orMapFragment
例如。
那么有人对这两个问题有任何解决方案吗?
