SQLiteException“无法提交 - 没有事务处于活动状态”，而与CONFLICT_REPLACE插入

Question

我有一些麻烦更新我的数据库。

这是日志：

这是我使用插入新的数据的代码：

int updateSize = 0;

// cvs is an ArrayList<ContentValues> array with each entry holding 
// the new values for a certain table
// I know I could use a Map but let's change one thing after another

for(ArrayList<ContentValues> list : cvs)
    updateSize += list.size();

Log.d(DEBUG_TAG, "Start updating databases");
Log.d(DEBUG_TAG, "update size: "+updateSize);

if(updateSize > 0) {

    dbHelper = ShaufelDatabaseHelper.getInstance(context);
    connection = dbHelper.getWritableDatabase();

    for(int i=0; i<cvs.length; i++) {
        String table;
        switch(i) {
            case 0: table = "cemeteries"; break;
            case 1: table = "customers"; break;
            case 2: table = "graves"; break;
            case 3: table = "orders"; break;
            case 4: table = "plants"; break;
            case 5: table = "plantevents"; break;
            case 6: table = "services"; break;
            case 7: table = "serviceevents"; break;
            default: throw new RuntimeException("wtf");
        }
        Log.d(DEBUG_TAG, "updating table "+table);

        for(ContentValues cv: cvs[i]) {
            // replace updated values, insert new ones
            connection.insertWithOnConflict(table, null, cv, SQLiteDatabase.CONFLICT_REPLACE);
        }
    }
}

关于这个奇怪的是，唯一的例外是不是每次抛出。它更像是这样的：

如果你启动应用程序并登录，更新工作。然后，如果您注销并重新登录的（不关闭应用程序）的更新再次发生，但这次例外。 如果您关闭应用程序（不只是迫切的家，但强制关闭了Android系统），直到注销并重新登录它会再次工作。 这些更新都包含相同的数据（目前我们正在测试这个东西），它是由相同的代码运行，但它只能一半的时间。

这是在Android 4.0.3上的HTC感觉运行。

Answer 1

1802是SQLITE_IOERR_FSTAT，当同时连接仍处于打开数据库文件被删除其发生。

你在做任何类型的文件删除的更新吗？
