发布到 Play 商店后发生 Firebase 错误

如何解决发布到 Play 商店后发生 Firebase 错误

在我的 android studio 调试中没有任何问题，但是当我将应用发布到 Playstore 时，我的应用在启动画面后关闭。我的应用程序使用 firebase，我必须将 SHA-1 从 Playstore 添加到我的 firebase 项目。但仍然无法崩溃：

我从游戏控制台得到的这个错误：

这是我的类别：

public class Category {
    private String id;
    private String name;
    private String picture_path;

    public Category(){
    }

    public Category(String id,String name,String picture_path) {
        this.id = id;
        this.name = name;
        this.picture_path = picture_path;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPicture_path() {
        return picture_path;
    }

    public void setPicture_path(String picture_path) {
        this.picture_path = picture_path;
    }
}

和数据库中的这个类别：

category database
