Question

我做什么： 我使用诺基亚Here-maps包装器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PolyLines在这两个点之间绘制方向。一切正常，使用Google Play服务但在诺基亚X上我无法获得用户位置，在地图对象上调用setMyLocationEnabled会抛出：

java.lang.IllegalArgumentException：提供者不存在：null at android.os.Parcel.readException（Parcel.java:1435）at android.os.Parcel.readException（Parcel.java:1385）at android.location.ILocationManager $存根$ 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）at com.nokia.maps.DeviceLocation.start（DeviceLocation.java:107）at 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.access $ 19（MapView.java:271）at at com.nokia.android.gms.maps.MapView $ 4.onFactoryInitializationCompleted（MapView.java:263）在com.nokia.maps.MapFactory $ 2.run（MapFactory.java:455）

MapsFragmentLegacy class

public class MapsFragmentLegacy extends Fragment {

    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，初始变焦，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：）
