android– 在Fragment中使用Google地图时,应用程序崩溃了

概述我第一次使用Fragments作为我的应用程序.我已经在其中一个片段中实现了GoogleMap,每当我选择带有地图的标签时,它会成功加载,但是一旦我进入其他活动的主菜单,它就会崩溃,我不知道为什么.这是我的崩溃日志：–03-2814:14:23.175:E/AndroidRuntime(18215):FATALEXCEPTION:m

在我的片段中,我实现了这样： –

@OverrIDe    public VIEw onCreateVIEw(LayoutInflater inflater, VIEwGroup container,            Bundle savedInstanceState) {        VIEw vIEw = inflater.inflate(R.layout.findmycar, null);        initVIEws(vIEw);        // Getting Google Play availability status        int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getActivity());        if(status!=ConnectionResult.SUCCESS){ // Google Play Services are not available            int requestCode = 10;            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, getActivity(), requestCode);            dialog.show();        }else { // Google Play Services are available            fm = (SupportMapFragment) getFragmentManager().findFragmentByID(R.ID.map);            map = fm.getMap();            if(map == null){                //Toast.makeText(getActivity(), "null", 0).show();            }            else{                map.setMyLocationEnabled(true);                // checking for the best provIDer and connectivity                // Getting LocationManager object from System Service LOCATION_SERVICE                locationManager = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);                if (netInfo !=null && netInfo.isConnected()) {                    if(isGpsEnable()){                        provIDer=LocationManager.GPS_PROVIDER;                        mLocation = locationManager.getLastKNownLocation(LocationManager.GPS_PROVIDER);                        if(mLocation==null){                            //onLocationChanged(location);                            provIDer=LocationManager.NETWORK_PROVIDER;                            mLocation = locationManager.getLastKNownLocation(LocationManager.NETWORK_PROVIDER);                            Log.d("Location","Location " + mLocation + " " + provIDer);                            if(mLocation!=null){                                onLocationChanged(mLocation);                            }                            else{                                Toast.makeText(getActivity(), "Unable to fetch your current location at the moment. Please try again later.", Toast.LENGTH_LONG).show();                            }                        }else {                            onLocationChanged(mLocation);                        }                    }                    else{                        showGpsAlert();                    }                }                else{                    Toast.makeText(getActivity(), "No internet connection", Toast.LENGTH_LONG).show();                }            }        }@OverrIDe    public voID onDestroyVIEw() {        super.onDestroyVIEw();        Fragment fragment = (getFragmentManager().findFragmentByID(R.ID.map));          if(fragment!=null){            Toast.makeText(getActivity(), "inif", 0).show();            FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();            ft.remove(fragment);            ft.commit();        }        else{        }    }    @OverrIDe    public voID onDestroy() {        super.onDestroy();    }    @OverrIDe    public voID onResume() {        super.onResume();        }    }

它完全运行,同时在onDestroyVIEw()方法中销毁引用但在该应用程序崩溃后,不知道该怎么做.

任何帮助都会很明显.
提前致谢.

解决方法:

试试这个,让我知道将以下代码放入onDestroyVIEw()

try{          SupportMapFragment fragment = ((SupportMapFragment) getFragmentManager().findFragmentByID(R.ID.map));          FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();          ft.remove(fragment);          ft.commit();        }catch(Exception e){        }
