i get an error on setOnItemClickListener of a listview

Question

I am trying to pass data through an intent, but its throwing an error I don't understand.

Activity:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_editor);
    conn = new ConnectionDetector(this);
    mEditorAdapater = new EditorAdapter(this, new ArrayList<ParseObject>());
    mListView = (ListView) findViewById(R.id.listEditor);
    mListView.setAdapter(mEditorAdapater);
    swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_refresh_layout_edit);
    swipeRefreshLayout.setOnRefreshListener(this);
    swipeRefreshLayout.post(new Runnable() {
        @Override
        public void run() {
            swipeRefreshLayout
                    .setRefreshing(true);
            queryPieces();
        }
    });

    mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

            String title = pieces.get(position).getString("title");
            String status = pieces.get(position).getString("status");
            String story = pieces.get(position).getString("story");
            String category = pieces.get(position).getString("category");
            String location = pieces.get(position).getString("location");
            String journo = pieces.get(position).getString("Journo");
            String objectId = pieces.get(position).getObjectId();
            // byte[] storyClip = pieces.get(position).getBytes("storyClip");
            Intent in = new Intent(Editor.this, EditPieceActivity.class);
            in.putExtra("title", title);
            in.putExtra("status", status);
            in.putExtra("story", story);
            in.putExtra("category", category);
            in.putExtra("location", location);
            in.putExtra("id", objectId);
            startActivity(in);
            //in.putExtra()
        }
    });

    pieces = new ArrayList<ParseObject>();
}

and this is the error am getting android is not being helpful in telling me what is wrong.

your pieces arraylist is empty...It is initialized but has no values it in...so check whether you are adding data to pieces arraylist properly — Shadow Droid, Oct 06 '15 at 14:26
You are sending empty data to your adapter always. See you are creating new object in your adapter. mEditorAdapater = new EditorAdapter(this, **new ArrayList()**); I am not sure how you are populating your listview. And logcat saying your `pieces` ArrayList is also empty. — Kunu, Oct 06 '15 at 14:38

This is a problem with your "pieces" array list-- it has nothing to do with starting a new activity or passing data through an intent. Maybe comment everything out in the onItemClick method and put

log.v("PIECES SIZE: ",""+pieces.size());

If this logs a 0, then you know your problem lies within that array.
