SQL请求后应用程序崩溃

Question

我执行SQL请求时，应用程序崩溃。

它说该表不存在，我也不知道为什么。

你能帮我吗？

这是logcat：

这是我正在做的请求：

List<Mushroom> MushroomList = new ArrayList<Mushroom>();
MushroomList = databaseHandler.getAllChampignons();
String res= "";

Log.e("List", MushroomList.toString());

for (Mushroom mushroom: MushroomList) {
    Log.e("NAME", mushroom.getName());
    res = res + mushroom.getId() + "\n";
}

createAlertBox("Resultats", res);

这是我的DataBaseHandler类的代码的一部分，其中的方法getAllChampignons：

这是我创建表的DataBaseHandler类，但是它不起作用.. 我只是向您展示有关蘑菇（蘑菇）的部分 你会发现： -方法onCreate在其中创建表香菇 -创建蘑菇对象的方法 -返回带有与SQL请求相对应的元素的列表的方法 -返回包含数据库所有元素的列表的方法 -方法
