问题描述

我已经读<解决方案href="http://stackoverflow.com/questions/19491675/failed-to-change-locale-for-db-data-data-my-easymedi-controller-databases-easy">Failed改变区域设置DB/data/data/my.easymedi.controller/databases/EasyMediInfo.db到EN_US但它不帮助我。我仍然有同样的错误。

I have read solution from Failed to change locale for db '/data/data/my.easymedi.controller/databases/EasyMediInfo.db' to 'en_US' but it doesnt help me. I still have the same error.

这些是我的 DBHelper 类。你可以看看，并帮助我？

它完美工作之前，但我已经做数据库一些升级，然后它停止工作。我想，这是这个错误的根源，但我不知道。

It worked perfectly before but I have made some upgrades of database and then it stopped work. I guess that this is the source of this error but I am not sure.

在此先感谢！

在您的要求：

我有打电话CreateDatabase方法在我的 MainActivity 类，你可以看到如下：

I have call createDataBase method in my MainActivity class, as you can see below:

package com.example.mgr;

        infDlaKandButton.setOnClickListener(new OnClickListener() {
            public void onClick(View arg0) {

            }

        });

        infDlaStudButton.setOnClickListener(new OnClickListener() {

        myDbHelper.openDataBase();

    }

    void ble() {
        Intent intent = new Intent();
        intent.setClass(MainActivity.this, SecondActivity.class);
        startActivity(intent);
    }

    @Override
    public void onClick(View arg0) {
        Toast.makeText(this, "ble", Toast.LENGTH_LONG).show();
        // TODO Auto-generated method stub

    }

}

是的，在 android_metadata 表存在于数据库中，并有* EN_US *的价值。

Yes, the android_metadata table exist in the database and has '*en_US*' value.

我已创建新的，非常简单的数据库 Drzewo.db 。当这个表只有2个表： andoid_metadata 和另一个（ Przyjeci ），那么一切正常！但后来我加入了新表，并设法使升级和我有同样的错误。

I have create new, very simple database Drzewo.db. When this table has only 2 tables: andoid_metadata and another one (Przyjeci) then everything works! But later I have added new table and tried to make an upgrade and I have the same error.

有我的登录（从这个新的数据库）：

我在上班的蚀的* JUNO * +的的Andr​​oid 4.2.2 的

I work on eclipse *juno* + Android 4.2.2

推荐答案

大概是数据库文件实际上是损坏。 你可以尝试打开它 sqlitebrowser

Probably the database file is actually corrupted. You can try to open it with sqlitebrowser

另外，还可以做一些其他的检查，并尝试将它的情况下恢复已损坏，如果您在计算机中安装的SQLite。您可以按照此步骤操作：

Also, you can do some other checks and try to restore it in case it is corrupted, if you install sqlite in your computer. You can follow this steps:

1. 在获取此处源码并安装它
2. 开启命令的SQLite oyour environnment变量路径添加路径，让您可以启动sqlite的命令处处

3. 进入该目录，其中有数据库，并启动SQLite的：

1. Get sqlite here and install it
2. Open command a add path to sqlite oyour environnment variable path to allow you to launch sqlite commands everywhere

3. Go to the directory, where you have the database, and launch SQLite:

sqlite3 yourfile.db

您可以通过检查数据库的完整性：

You can check the database integrity by:

pragma integrity_check;

如果它说，该文件是确定的，那么我们就输了！如果已损坏，让试图恢复它。

If it says that the file is ok, then we are lost! If it is corrupted, lets try to restore it.

有时，损坏的sqlite3的数据库，最好的解决办法是简单而有效：转储和恢复

Sometimes the best solution for a corrupted sqlite3 database is simple yet effective: Dump and Restore

1. 您的数据导出到一个SQL文件：

1. Export your data to an sql file:

echo .dump | sqlite3.exe yourdbname.db > yourdbname.sql

更改文件名MV yourdbname.db yourdbname.db.original

Change file name mv yourdbname.db yourdbname.db.original

用SQL创建一个新的数据库。

Create a new database with your sql.

sqlite3.exe -init yourdbname.sql yourdbname.db

打开使用SQLite浏览器的新文件，看看会发生什么！

Open the new file with sqlite browser, and see what happens!
