Codename One: SQLite connection errors

I am trying to connect an SQLite database (saved in the app folder) to a picker component (accepting strings). The following is the code I used (previously advised):

Database db = null;
Cursor cur = null;
try {
    db = Display.getInstance().openOrCreate("FoodAndBeverage.db");
    if(selectItem.getText().startsWith("Still Water")) {
        cur = db.executeQuery(selectItem.getText());
        int columns = cur.getColumnCount();
        addItem.removeAll();
        if(columns > 0) {
            boolean next = cur.next();
            if(next) {
                ArrayList<String[]> data = new ArrayList<>();
                String[] columnNames = new String[columns];
                for(int iter = 0 ; iter < columns ; iter++) {
                    columnNames[iter] = cur.getColumnName(iter);
                }
                while(next) {
                    Row currentRow = cur.getRow();
                    String[] currentRowArray = new String[columns];
                    for(int iter = 0 ; iter < columns ; iter++) {
                        currentRowArray[iter] = currentRow.getString(iter);
                    }
                    data.add(currentRowArray);
                    next = cur.next();
                }
                Object[][] arr = new Object[data.size()][];
                data.toArray(arr);
                addItem.add(BorderLayout.CENTER, new Table(new DefaultTableModel(columnNames, arr)));
            } else {
                addItem.add(BorderLayout.CENTER, "Query returned no results");
            }
        } else {
            addItem.add(BorderLayout.CENTER, "Query returned no results");
        }
    } else {
        db.execute(selectItem.getText());
        addItem.add(BorderLayout.CENTER, "Query completed successfully");
    }
    addItem.revalidate();
} catch(IOException err) {
    Log.e(err);
    addItem.removeAll();
    addItem.add(BorderLayout.CENTER, "Error: " + err);
    addItem.revalidate();
} finally {
    Util.cleanup(db);
    Util.cleanup(cur);
}

However, I get the following error messages:

This may be due to the app not recognising the database. To clarify, where does the database file need to be saved? I have currently saved the file in the app folder. View of app folder showing where the database file (highlighted) is saved.
