Question

我在Play商店有一个应用程序，每天我收到错误的报告。但是在某些设备中会出现此错误，但不是全部。我有5000人使用我的应用程序，并且没有得到该错误。

所以：我收到的报告错误：

拜托，有人可以帮帮我吗？

我的应用的链接： https://play.google.com/store/apps/details?id=com.jeanjn.guiadeacademia

我的脚本数据库：

CREATE TABLE IF NOT EXISTS versaoLancada(_id integer primary key,versao integer);
CREATE TABLE IF NOT EXISTS Atualizacao(_id integer primary key,versao datetime);
CREATE TABLE IF NOT EXISTS Exercicio (_id INTEGER PRIMARY KEY,nome VARCHAR(300),categoria integer,descricao varchar(900),url varchar(900), FOREIGN KEY(categoria) references categoria(_id));
CREATE TABLE IF NOT EXISTS Categoria(_id integer primary key,nome varchar(300));
insert into Atualizacao (versao) values (1);
insert into Categoria (nome) values ('Selecione a categoria  ');
insert into Categoria (nome) values ('Abdominal');

这只是其中的一部分。

DataBase类：

    package com.jeanjn.guiadeacademia.Control;

import android.content.Context;
import android.content.ContextWrapper;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;


public class DataBase extends ContextWrapper{
    SQLiteDatabase db = null;

    public DataBase(Context base) {
        super(base);
        db = openOrCreateDatabase("academia.db", Context.MODE_PRIVATE, null);
    }

    public void dropDB()
    {
        this.getDatabasePath("academia.db").delete();
    }

    public Cursor getData(String command)
    {
        Cursor c = db.rawQuery(command, null);
        return c;
    }

    public SQLiteDatabase getDataBase()
    {
        return openOrCreateDatabase("academia.db", Context.MODE_PRIVATE, null);
    }

    public void setData(String command)
    {
        db.execSQL(command);
    }

    public int getInt(String command,String column)
    {
        Cursor c = db.rawQuery(command, null);
        c.moveToNext();
        return c.getInt(c.getColumnIndex(column));
    }

    public void closeDB(Cursor c)
    {
        if(c != null)
            c.close();
        if(db != null)
            db.close();
    }
}

该方法调用setData（...）

public static void atualizar(Scanner s,Context cx)
    {
        while(s.hasNextLine())
        {
            String line = s.nextLine();
            if(line.trim().isEmpty())
                break;
            try{
                DataBase db = new DataBase(cx);
                db.setData(line);
                db.closeDB(null);
            }catch(Exception e)
            {
                Suporte.alertar(cx, "Erro ao cadastrar base de dados!\nPor favor, contate-nos no menu 'Fale conosco'.");
            }
        }
    }

我如何获得txt：

private void cadastrar(Context cx)
    {
        InputStream is = getClass().getResourceAsStream("0.txt");
        Scanner s = null;
        s = new Scanner(is);
        atualizar(s, cx);
    }

Answer 1

只是一个猜测：

CREATE TABLE ... Exercicio ... references categoria(_id));
CREATE TABLE ... Categoria

您应该在创建表Categoria之前创建表Exercicio，因为Exercicio依赖于现有的Categoria。

如果我的猜测是错误的：如果你将sql-line的内容添加到异常消息中，你就会知道出了什么问题：

        }catch(Exception e)
        {
            addToErrorLog("Error executing " + line +":" + e.getMessage());
            Suporte.alertar(cx, "Erro ao cadastrar base de dados!\nPor favor, contate-nos no menu 'Fale conosco'.");
        }
