Android Google Maps CameraUpdateFactory未初始化

Android Google Maps CameraUpdateFactory未初始化,android,google-maps,Android,Google Maps,通过crashlytics给我一个错误,我从用户体验中得到了一些报告 Fatal Exception java.lang.NullPointerException CameraUpdateFactory is not initialized 这不是一个常规的崩溃,因为它不会对每个用户都发生,但它变得太常规了,我需要解决它 我曾读到,如果地图没有初始化,这可能会发生,我想我已经讨论过了 if(googleMap!=null){ googleMap

通过crashlytics给我一个错误,我从用户体验中得到了一些报告

Fatal Exception java.lang.NullPointerException         
CameraUpdateFactory is not initialized
这不是一个常规的崩溃,因为它不会对每个用户都发生,但它变得太常规了,我需要解决它

我曾读到,如果地图没有初始化,这可能会发生,我想我已经讨论过了

if(googleMap!=null){
                googleMap.animateCamera(CameraUpdateFactory.newLatLng(selectedLatLng));
            }  
另一个可能的原因可能是设备上没有google play服务,或者已经过时,我也添加了一些验证

   public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(FuelsFragment.this.getActivity());

    // Showing status
    //CAMERAUPDATE FACTORY CRASH CAN BE A RESULT OF GOOGLE PLAY SERVICES NOT INSTALLED OR OUT OF DATE
    //ADDITIONAL VERIFICATION ADDED TO PREVENT FURTHER CRASHES

    //https://github.com/imhotep/MapKit/pull/17
    if(status == ConnectionResult.SUCCESS)
    {
        mMapFragment = ReepMapFragment.newInstance();

        FragmentTransaction fragmentTransaction = getChildFragmentManager().beginTransaction();
        fragmentTransaction.add(R.id.mapContainer, mMapFragment);
        fragmentTransaction.commit();

    }
    else if(status == ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED){

        reep.toastNotify("You need to update Google Play Services in order to view maps");
    }
    else if (status==ConnectionResult.SERVICE_MISSING){
        reep.toastNotify("Google Play service is not enabled on this device.");
    }
之后,我不确定下一步该怎么做,因为这不会发生在每个用户身上


如果有人对发生这种情况的原因有任何想法,我将非常感谢您的输入

您是否应该执行
类.forName()
?对于
CameraUpdateFactory
?在
try-catch

中,我得到了相同的错误,尽管我从MapView中获得了一个非空的GoogleMap对象。我通过显式调用MapsInitializer解决了这个问题,尽管文档中说不需要它

我的应用程序片段通过以下方式设置地图视图:

@Override public View 
onCreateView(LayoutInflater inflater, ViewGroup container,
             Bundle savedInstanceState)
{
    View view = inflater.inflate(R.layout.map_panel, container, false);
    mapView = (MapView) view.findViewById(R.id.map_view);
    mapView.onCreate(savedInstanceState);
    configureMap(mapView.getMap());
    return view;
}

private void 
configureMap(GoogleMap map, double lat, double lon)
{
    if (map == null)
        return; // Google Maps not available
    try {
        MapsInitializer.initialize(getActivity());
    }
    catch (GooglePlayServicesNotAvailableException e) {
        Log.e(LOG_TAG, "Have GoogleMap but then error", e);
        return;
    }
    map.setMyLocationEnabled(true);
    LatLng latLng = new LatLng(lat, lon);
    CameraUpdate camera = CameraUpdateFactory.newLatLng(latLng);
    map.animateCamera(camera);
}

在我添加对MapsInitializer的调用之前,我会从CameraUpdateFactory得到一个异常。添加呼叫后,CameraUpdateFactory始终会成功。

有时可能是由于旧版本的Google Play服务造成的,请更新Google Play服务。它可能会帮助您

只需使用MapsInitializer.initialize而不使用try catch,因为它不会在最新版本的Google Play services中抛出GooglePlayServicesNotAvailableException,该异常已通过软件包版本5084032进行验证。

我的
MapUtil
中的某个内容处理此情况:

public static void animateCamera(final MapView mapView, final GoogleMap map, final LatLng location) {
        try{
            CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(location, getBetterZoom(map));
            map.animateCamera(cameraUpdate);
        }catch(Exception e) {
            MapsInitializer.initialize(mapView.getContext());
            if (mapView.getViewTreeObserver().isAlive()) {
                mapView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
                    @SuppressLint("NewApi")
                    @Override
                    public void onGlobalLayout() {
                        GlobalyLayoutListenerUtil.removeGlobalLayoutListener(mapView, this);
                        animateCamera(mapView, mapView.getMap(), location);
                    }
                });
            } else {
                if(map != null){
                    map.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {
                        @Override
                        public void onMapLoaded() {
                            if(location != null){
                                animateCamera(mapView, mapView.getMap(), location);
                            }
                        }
                    });
                }
            }
        }

    }

由于缺少GlobalyLayoutListenerUtil和getBetterZoom,无法完全使用上述代码-请发布缺少的代码。谢谢
