java android exception crash verifyerror

Stuck with Java.lang.VerifyError for a class created in onCreate()

I'm having a hard time trying to resolve this awful VerifyError, and can't find a solution.

I've seen a few threads like this one or this one but I'm not using 3rd party libraries nor calls to String.isEmpty() as it is suggested.

I just use supportv4 and v7 for these imports:

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;

My onCreate in MapActivity looks like this:

@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 is defined by this:

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;
}

Here, I have 3 warnings: Type safety: a generic array of arrayList is created for a varargs parameter. One is for lAllStationsTemp, the second is for mAllStations, and the last one is for lAllStationsTemp2. I'm not sure wether this warning changes anything to my problem, but it's here.

And my DataController contains this:

Any suggestion would be greatly appreciated. This error occurs on Android 2.2. Thanks for your help.

Solution

Ok, I just found the cause of this error. After several weeks, I had to ask to find it :)

I was focusing on usual cases where this error occurs, but my code wasn't at fault. I didn't see this warning: "VFY: arbitrarily rejecting large method (regs=93 count=23019)".

It appears that my constructor had too many variables declared in it, resulting in a memory management problem, as explained here.

My constructor was like this:

public DataController() {

    ArrayList<String> lConnection_S1 = new ArrayList<String>(Arrays.asList("T1"));
    ArrayList<String> lConnection_S2 = new ArrayList<String>(Arrays.asList("T1", "T2"));
    ...
    ArrayList<String> lConnection_S2034 = new ArrayList<String>(Arrays.asList("T1", "T2"));

    mTram1Stations = new ArrayList<StationItem>(Arrays.asList(
        new StationItem("Station 1","T1",0,0,lConnection_S1),
        new StationItem("Station 2","T1",0,0,lConnection_S2)
    ));

    mBus1Stations = new ArrayList<StationItem>(Arrays.asList(
        new StationItem("Station 1","B1",0,0,lConnection_S1),
        new StationItem("Station 2","B1",0,0,lConnection_S2)
    ));

    mTram1Locations = new ArrayList<LatLng>(Arrays.asList(
        new LatLng(40.190, 3.20),
        new LatLng(40.191, 3.21),
        new LatLng(40.192, 3.22)
    ));
}

I didn't write all my variables as it wouldn't be readable, but as you can see, it goes up to lConnection_S2034, and raises the VerifyError on Android 2.2.

What I did to solve my problem was declaring these local variables as instance variables, and initialising them in the constructor like this:

public class DataController {

    ArrayList<String> mConnection_S1;
    ArrayList<String> mConnection_S2;
    ...
    ArrayList<String> mConnection_S2034;

    public DataController() {

        mConnection_S1 = new ArrayList<String>(Arrays.asList("T1"));
        mConnection_S2 = new ArrayList<String>(Arrays.asList("T1", "T2"));
        ...
        mConnection_S2034 = new ArrayList<String>(Arrays.asList("T1", "T2"));
    }
}
