Сбой приложения при открытии фрагмента

/ 26 апреля 2018

Привет всем Моё приложение зависает, когда вкладки открываются случайным образом, и выдает ошибку, подобную этой, в моем logcat. Любой может помочь мне исправить это

В этом фрагменте я включил отображение информации о карте в заголовке Listview, для которого я использую SupportMapFragment

Вот мой следующий код 

public class ChainTab extends Fragment implements ResponseListner, OnMapReadyCallback, LocationListener, GoogleMap.OnMarkerClickListener {

    String TAG = ChainTab.class.getSimpleName();

    String bottleId;
    String url;

    ListView bottleChainListView;
//    NonScrollListView bottleChainListView;

    Context context;

    View rootView;

    String responseVal;

    private GoogleMap mMap;
    private LocationManager mLocationManager = null;
    private String provider = null;
    private Marker mCurrentPosition = null;
    ProgressDialog PD;
    private List<BottleInfoModel> bottleInfoModelList;
    private List<CreatedAt> createdAtList;
    private List<UpdatedAt> updatedAtList;
    private List<Scans> scansList;
    private Polyline mPolyline = null;
    private LatLng mSourceLatLng = null;
    private LatLng mDestinationLatLng = null;

    TextView serialNoTV, entityNameTV, productTypeChainTV, originTV, getQTYUOM, entityType;



    public View onCreateView(LayoutInflater inflater, ViewGroup viewGroup, Bundle savedInstanceState) {

        rootView = inflater.inflate(R.layout.chain_tab, viewGroup, false);

        bottleInfoModelList = new ArrayList<>();
        createdAtList = new ArrayList<CreatedAt>();
        updatedAtList = new ArrayList<>();
        scansList = new ArrayList<>();
        context = getActivity();


        bottleChainListView = rootView.findViewById(R.id.bottleChainListView);

        return rootView;
    }



    public void displayMsgs(NdefMessage[] msgs) {



        if (msgs == null || msgs.length == 0)
            return;

        StringBuilder builder = new StringBuilder();
        List<ParsedNdefRecord> records = NdefMessageParser.parse(msgs[0]);
        final int size = records.size();

        for (int i = 0; i < size; i++) {
            ParsedNdefRecord record = records.get(i);
            String str = record.str();
            builder.append(str).append("\n");
        }


        Log.i(TAG,"NFC Id Value is :: "+builder.toString().trim());

        else
            Log.i(TAG, "Context Value is  Null....154");
    }
