My activity with the database has a problem, because I created class right and Android Studio is not showing any errors, but when I run it on the mobile when opening activity that has the bank of data it closes.

Would anyone have any idea what it is?

package BankSimples (bank)

Simple Bank

package BancoSimples;

import java.io.Serializable;

public class SimplesBanco implements Serializable{
    public long id;
    public String timeum;
    public String timedois;
    public String golone;
    public String goldois;


    public SimplesBanco(long id, String timeum, String timedois, String golone, String goldois){
        this.id = id;
        this.timeum = timeum;
        this.timedois = timedois;
        this.golone = golone;
        this.goldois = goldois;
    }

    @Override
    public String toString() {
        return timeum;
    }
}

        if (id != -1) {

        }

        db.close();
        return id;
    }
