运行我的代码时，我得到了这个 CursorWindowAllocationException：

代码： 

     try{
        Uri uri;
        uri = RawContactsEntity.CONTENT_URI;

        final String selection = Data.CONTACT_ID + "=?";
        final String[] selectionArgs = new String[] { contactId.id };
        cur = _resolver.query(uri, null, selection, selectionArgs, null);
        if (cur == null)
            return null;
        if (cur.moveToFirst() == false)
        {
            cur.close();
            return null;
        }
        entityIterator = RawContacts.newEntityIterator(cur);

        if (entityIterator == null)
        {
            Logger.error(TAG, "EntityIterator is null");
            return null;
        }

        while (entityIterator.hasNext())
        {
            Entity entity = entityIterator.next();
            for (NamedContentValues namedContentValues : entity
                    .getSubValues())
            {
                ContentValues contentValues = namedContentValues.values;
                String key = contentValues.getAsString(Data.MIMETYPE);
                if (key != null)
                {
                    contentValuesList.add(contentValues);
                }
            }
        }
    }
    finally
    {
        if (cur != null)
        {
            cur.close();
        }
        if (entityIterator != null)
        {
            entityIterator.close();
        }
    }

但有时我会得到这个例外：

虽然这种崩溃并不容易重现，但它确实偶尔会发生。有谁知道为什么会发生这种情况？
