该应用程序运行良好,但在某些设备上关闭,此应用程序代码

我的代码是:

 public List<item> getListProduct() {

        item product = null;
        List<item> productList = new ArrayList<>();
        openDatabase();
        Cursor cursor = mDatabase.rawQuery("SELECT * FROM tablo", null);
        cursor.moveToFirst();
        while (!cursor.isAfterLast()) {
            product = new item(cursor.getInt(0),
                               cursor.getString(1),
                               cursor.getString(2),
                               cursor.getString(3),
                               cursor.getString(4),
                               cursor.getString(5),
                               cursor.getInt(6));
            productList.add(product);
            cursor.moveToNext();
        }
        cursor.close();
        closeDatabase();
        return productList;
    }

我得到这个错误

Caused by: android.database.sqlite.SQLiteException
