Android SQLite数据库已损坏

此链接完全描述了我的问题： http://old.nabble.com/Android-database-corruption-td28044218.html#a28044218

现在大约有300人使用我的Android应用程序,每次使用此堆栈跟踪向服务器发送崩溃报告时：

android.database.sqlite.sqliteDatabaseCorruptException: database disk image is malformed
    at android.app.ActivityThread.performlaunchActivity(ActivityThread.java:2596)

    at android.database.AbstractCursor.movetoPosition(AbstractCursor.java:171)
    at android.database.AbstractCursor.movetoFirst(AbstractCursor.java:248)

结果是应用程序崩溃并且数据库中的所有数据都丢失了.

需要注意的一点是,每次我读取或写入数据库时​​,我都会得到一个新的sqliteDatabase,并在完成后立即将其关闭.我这样做是为了防止这种腐败错误.

我还尝试使用单个静态对象同步所有数据库读取和写入,这似乎没有帮助.

这可能只是一个sqlite错误吗？

我在这里找到了与内置电子邮件应用程序类似的错误：http://code.google.com/p/android/issues/detail?id=5610.

这是我的代码：

public class keyvalueTableAdapter extends BaseTableAdapter {

    private String tableName;
    private String keyColumnName;
    private String valueColumnName;

    public keyvalueTableAdapter(Context context,String tableName,String keyColumnName,String valueColumnName) {
        super(context);
        this.tableName = tableName;
        this.keyColumnName = keyColumnName;
        this.valueColumnName = valueColumnName;
    }

    protected String getStringValue(int key) {
        Cursor cursor = null;
        sqliteDatabase db = null;
        String value;

        try {
            db = dbOpenHelper.getReadableDatabase();
            cursor = db.query(true,tableName,new String[] { valueColumnName },keyColumnName + "=" + key,null,null);

            if ((cursor.getCount() == 0) || !cursor.movetoFirst()) {
                value = null;
            } else {
                value = cursor.getString(0);
            }
        } finally {
            if (cursor != null) cursor.close();
            if (db != null) db.close();
            dbOpenHelper.close();
        }

        return value;
    }
}


public abstract class BaseTableAdapter {

    protected DbOpenHelper dbOpenHelper;

    public BaseTableAdapter(Context context) {
        this.dbOpenHelper = new DbOpenHelper(context,DatabaseSettings.DATABASE_NAME,DatabaseSettings.DATABASE_VERSION);
    }

}

解决方法

“the DB holds session information so
it’s not very feasible to do a backup.
The data changes by the minute”

您应该尝试使用SharedPreferences：它存储键值对(在后台,它使用文件).
存储值：

SharedPreferences sp=MyActivity.getSharedPreferences("Name",Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.putString("key",value);
editor.putBoolean("another",true);
editor.commit();

检索数据：

sp.getString("key","Not found"); 
// "Not found" is the default value
// if sp does not contain the specified key
sp.getBoolean("another",false); 
// false is the default value
// if sp does not contain the specified key

有关更详细的说明,请参见getSharedPreferences和SharedPreferences.
