Well, it's not a real code snippet but..

since I found my self doing the monkey job of buildling a
sqlite helper class as suggested in many books / examples /
tutorials a couple of time , I thought it would have been funnier to write a script to automatize
this process rather than doing it by hand (again(.

So you can find the results of my efforts at http://github.com/fedepaol/Android-sql-lite-helper

The usage is quite easy: it's a python script. You provide the
description of the tables (in java terms) in a file, and it
automatically generate the helper .java.

I don't know if something similar and probably better already exists,
I really liked trying to make this work.

The script is pretty young, so if you have any questions or issues or
suggestions please contact me.
