Android Objectbox删除实体并删除ToOne<&燃气轮机；在另一个实体中链接到它。应用程序现在仅在进行更改时在第一个构建变体上工作

在我的应用程序中，我有两个实体

CardEntity

和

DeckCard

。我想完全删除

CardEntity

，并更新

DeckCard

以不再引用它

public class CardEntity extends BaseEntity {

    private char letter;
    private int bonus;

    public CardEntity() {
    }

    public CardEntity(char letter) {
        this(letter, 0);
    }

    public CardEntity(char letter, int bonus) {
        this.letter = letter;
        this.bonus = bonus;
    }

    public char getLetter() {
        return letter;
    }

    public int getBonus() {
        return bonus;
    }

    public void setLetter(char letter) {
        this.letter = letter;
    }

    public void setBonus(int bonus) {
        this.bonus = bonus;
    }
}

及

正如预期的那样，这很好。然而，它只适用于我当时在Android Studio中选择的任何构建变体。我所说的selected是指下一次应用程序运行并且更新

objectbox models/default.json

文件时

若我使用的是调试构建变量，那个么它在发布构建变量上就不起作用，反之亦然

我非常确定，当我重命名某个东西或更改它的类型时，我只需要使用

Uid

命令。在这个例子中，我两个都不做，我删除并创建了一些新的东西

下面是objectbox创建的默认.json`文件更改的git差异

更新：为使问题更加清晰…

更新：观察到的行为无法在当前版本的ObjectBox（如2.5.1）中重现，而只能在旧版本（2.0.0）中重现

总结：

• 您打算将两个实体类型的属性“合并”为一个
• CardEntity已删除
• DeckCard获得两个附加属性，并将ToOne删除到CardEntity

---

对不起，不能将两个合并为一个。完全摆脱CardEntity，而不是在DeckCard中使用它，我只想使用这两个原语。构建之间的实体类也没有区别。至于“不工作”，我会抓取一个堆栈跟踪，并在另一条评论中发布它-它从我认为是崩溃开始的地方开始，我不知道崩溃实际上在哪里结束，所以可能有很多“不工作”的后遗症，即应用程序编译、安装、启动，然后在不到1s的时间内崩溃。在任何真正提到应用程序包名称的错误日志中都没有java错误，上面的pastebin是基于对整个电话日志的搜索，但至少它提到了包。“完全摆脱CardEntity，而不是将其包含在DeckCard中，我只想使用这两个原语。”->是的。我想我们指的是同一件事。“合并”两个实体的属性。。。我会澄清。。。对于本机崩溃，我刚刚创建了一个-看起来肯定像一个bug…通过库更新确认所有问题都已修复。谢谢@Markus

public class DeckCard extends BaseEntity {

    private Integer position;
    private char letter;
    private int bonus;

    public DeckCard() {
    }

    public DeckCard(Integer position, char letter, int bonus) {
        this.position = position;
        this.letter = letter;
        this.bonus = bonus;
    }

    public Integer getPosition() {
        return position;
    }

    public void setPosition(Integer position) {
        this.position = position;
    }

    public char getLetter() {
        return letter;
    }

    public void setLetter(char letter) {
        this.letter = letter;
    }

        return bonus;
    }

    public void setBonus(int bonus) {
