java - onCreate() で作成されたクラスの Java.lang.VerifyError でスタックする

Question

このひどい VerifyError を解決するのに苦労しており、解決策が見つかりません。

このスレッドまたはこのスレッドのようなスレッドをいくつか見ましたが、サードパーティのライブラリを使用したり、提案されている String.isEmpty() を呼び出したりしていません。

これらのインポートには supportv4 と v7 を使用します。

import android.support.v7.app.ActionBarActivity;  
import android.support.v4.app.FragmentManager;  
import android.support.v4.app.FragmentTransaction;  
import android.support.v4.app.LoaderManager;  
import android.support.v4.app.TaskStackBuilder;  
import android.support.v4.content.Loader;  

MapActivity の onCreate は次のようになります。

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

    if (mDataController == null) {
        mDataController = new DataController();
    }

    initData();

    FragmentTransaction fragmentTransaction = mFragmentManager.beginTransaction();
    fragmentTransaction.replace(R.id.container, mMapViewFragment, "MapViewFragment");
    fragmentTransaction.commit();
}

initData は次のように定義されます。

public void initData() {

    mListLines = Arrays.asList("ALL",
                  DataController.LINE_NAME_TRAM_1,
                  DataController.LINE_NAME_TRAM_2,
                  DataController.LINE_NAME_BUS_1);

    List<ArrayList<StationItem>> lAllStationsTemp = Arrays.asList(
                                        DataController.mTram1Stations,
                                        DataController.mTram2Stations,
                                        DataController.mBus1Stations);

    mAllStationsTramsBus = new ArrayList<StationItem>(DataController.mTram1Stations);
    for (int i=0; i<lAllStationsTemp.size(); i++) {
        List<StationItem> lCurrentLineStations = lAllStationsTemp.get(i);
        for (final StationItem lStationToInsert : lCurrentLineStations)
        {
            for (int j=0; j<mAllStationsTramsBus.size(); j++) {
                StationItem lCurrentStation = mAllStationsTramsBus.get(j);
                if (lStationToInsert.mStationName.equals(lCurrentStation.mStationName)) {
                    mAllStationsTramsBus.remove(j);
                }
            }
            mAllStationsTramsBus.add(lStationToInsert);
        }
    }

    //Sort results by station name property of object StationItem

    Collections.sort(mAllStationsTramsBus);

    mAllStations = new ArrayList<ArrayList<StationItem>>(Arrays.asList(
                    mAllStationsTramsBus,
                    mDataController.getStationListFromList(DataController.mTram1Stations),
                    mDataController.getStationListFromList(DataController.mTram2Stations),
                    mDataController.getStationListFromList(DataController.mBus1Stations)
                    ));


    List<ArrayList<StationItem>> lAllStationsTemp2 = Arrays.asList(
            DataController.mTram1Stations,
            DataController.mTram2Stations
            );


    mAllStationsTrams = new ArrayList<StationItem>(DataController.mTram1Stations);
    for (int i=0; i<lAllStationsTemp2.size(); i++) {
        List<StationItem> lCurrentLineStations = lAllStationsTemp2.get(i);
        for (final StationItem lStationToInsert : lCurrentLineStations)
        {
            for (int j=0; j<mAllStationsTrams.size(); j++) {
                StationItem lCurrentStation = mAllStationsTrams.get(j);
                if (lStationToInsert.mStationName.equals(lCurrentStation.mStationName)) {
                    mAllStationsTrams.remove(j);
                }
            }
            mAllStationsTrams.add(lStationToInsert);
        }
    }

    //Sort results by station name property of object StationItem

    Collections.sort(mAllStationsTrams);

    mMapViewFragment.mAllStations = mAllStations;
}

ここで、3 つの警告があります: 型の安全性: arrayList のジェネリック配列が varargs パラメーターに対して作成されます。1 つは lAllStationsTemp 用、2 番目は mAllStations 用、最後の 1 つは lAllStationsTemp2 用です。この警告によって問題が変わるかどうかはわかりませんが、ここにあります。

どんな提案でも大歓迎です。このエラーは Android 2.2 で発生します。ご協力いただきありがとうございます。
