在我正在编程的android应用程序中，我试图使用gson库保存带有自定义对象的arraylist。如果我称之为

private void saveData(){
    SharedPreferences sharedPreferences = getSharedPreferences("shared preferences",MODE_PRIVATE);
    SharedPreferences.Editor editor =  sharedPreferences.edit();
    Gson gson = new Gson();
    String json = gson.toJson(recipe_items);
    editor.putString("task list",json);
    editor.apply();
}

保存功能，我的应用程序崩溃，并显示以下错误消息：

E/AndroidRuntime: FATAL EXCEPTION: main

RecipeCroll是我的主要活动类，recipe_items是带有自定义对象的arraylist。
这是保存在arraylist中的类

public class recipe_item {
private Drawable mImageResource;
private String time;
private String title;
private String manual;
private ArrayList<Ingredient> ingredients;
public recipe_item(Drawable ImageResource,String time1, String title1,String manual1 , ArrayList<Ingredient> ingredients1){
    mImageResource = ImageResource;
    time = time1;
    title = title1;
    manual = manual1;
    ingredients = ingredients1;
}
public Drawable getmImageResource(){
    return mImageResource;
}
public String getTime(){
    return time;
}
public String getTitle(){
    return title;
}
public String getManual() { return manual; }
public ArrayList<Ingredient> getIngredients() {
    return ingredients;
}

}
我已经试过了
将所有对话框字段设置为 transient
使用排除策略跳过名为mcontext的字段，但它只会给我带来更多错误
我不能做什么
更改popupcue类的代码，因为它是随android提供的
（sry表示英语不好，我很乐意回答）
我在网上找到了什么
这可能就是我正在处理的类：https://github.com/fonix232/scoverre/blob/master/reversed/framework/com/samsung/android/directpeninput/popupcue.java
