我做什么： 我使用诺基亚 Here-maps wrapper v2 来显示带有一个自定义标记和用户位置的地图。然后我使用折线在这两个点之间绘制方向。Google Play 服务一切正常，但在诺基亚 X 上我无法获取用户位置，调用地图对象上的 setMyLocationEnabled 会抛出：

java.lang.IllegalArgumentException：提供程序不存在：在 android.os.Parcel.readException(Parcel.java:1385) 在 android.location.ILocationManager$ 的 android.os.Parcel.readException(Parcel.java:1435) 处为 null Stub$Proxy.requestLocationUpdates(ILocationManager.java:540) 在 android.location.LocationManager.requestLocationUpdates(LocationManager.java:836) 在 android.location.LocationManager.requestLocationUpdates(LocationManager.java:430) 在 com.nokia.maps.DeviceLocation .M(DeviceLocation.java:380) 在 com.nokia.maps.DeviceLocation.start(DeviceLocation.java:107) 在 com.nokia.maps.PositioningManager.start(PositioningManager.java:171) 在 com.nokia.android。 gms.maps.GoogleMap.setPositionManagerEnabled(GoogleMap.java:1442) 在 com.nokia.android.gms.maps.GoogleMap.setMyLocationEnabled(GoogleMap.java:1420) 在 com.nokia。android.gms.maps.GoogleMap.onInitializationComplete(GoogleMap.java:696) 在 com.nokia.android.gms.maps.MapView.attachMapToMapViewSetup(MapView.java:293) 在 com.nokia.android.gms.maps.MapView。在 com.nokia.android.gms.maps.MapView$4.onFactoryInitializationCompleted(MapView.java:263) 在 com.nokia.maps.MapFactory$2.run(MapFactory.java:455) 访问 $19(MapView.java:271)

    android:layout_height="match_parent"
    android:id="@+id/map"

    private MapsFragmentLegacy mMapFragment;

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

    private void setUpMapIfNeeded() {
        try {
            if(mMapFragment == null) {
                if (MyWrapper.hasHere(context)) {

                } else {
                    mMapFragment = new MapsFragmentGoogle();
                }
                FragmentManager fragmentManager = getSupportFragmentManager();
                fragmentManager.beginTransaction().add(R.id.map_container, mMapFragment).commit();
            }
        }
        catch(Exception e){
            if(DEBUG)e.printStackTrace();

            mMap.setMyLocationEnabled(true);
            mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(mLatLng, 16));
            mMap.addMarker(new MarkerOptions()
                .icon(BitmapDescriptorFactory.fromResource(R.drawable.marker))

MapsFragmentLegacy 类

public class MapsFragmentLegacy extends Fragment {
    protected static int FRAGMENT_LAYOUT = R.layout.maps;
    protected static final int FRAGMENT_ID = R.id.map;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        return inflater.inflate(FRAGMENT_LAYOUT, container, false);
    }
}

使用相机位置、初始缩放、工作缩放控件和自定义标记正确显示地图。任何帮助将不胜感激 ：）
