Database randomly deletes itself every so often

I have a normal SQLite database in my app, managed through my own ContentProvider and implemented via SQLiteOpenHelper.

On the Droid only, every few weeks or so, the database just disappears. I have several users who wrote me about that, and I've seen it myself too now. I added some debug info (hard to repro when you only see it every few weeks), and in one instance, it just happened inbetween widget updates - first, the widget is displayed and shows the data just fine, the next time, the SQLiteOpenHelper's onCreate is called.

再一次,这只在机器人身上。我从未在G1上看到过。我从来没有关闭数据库,但它是一个内容提供商,听起来好像我不应该首先做这件事(我记得Hakbod说,这个想法是,OS将关闭应用程序的过程中,必要时,这将自动关闭数据库)。

有什么想法吗?
