Re: [android-developers] ORM library
Your points are valid and to similar to my own concerns. While I doubt that ORM would save the day, it would be nice to have a solution that would reduce the large amount of boilerplate that comes along with maintaining table structures. I'll take a look at ORMLite - thanks for your thoughts. On Thursday, 9 May 2013 17:17:28 UTC+1, mbanzon wrote: I have looked at quite a few ORM libs but have always decided to go without them.

[android-developers] ORM library
