什么是更新数据库架构的最佳实践？我可以用SQL命令发送一个文本文件。该应用程序可以检查该文本文件并执行所需的命令。我猜，我将有一个标志，表明该更新已经完成。我还没有找到一个方法来删除一个文件从应用程序，这将是后做数据库进行了更新，最好的东西的资源文件夹。

What is the best practice for updating the DB schema? I could send a text file with the SQL commands. The app could check the text file and execute the commands needed. I am guessing then I will have a flag to indicate that the update has been done. I havent found a way to delete a file in the asset folder from the app, which would be the best thing to do after the DB was updated.

在这个有什么想法？

您可能要重写

onUpdate(SQLiteDatabase db,int old Version,int newVerison)
