DB model
Using Crom library you can simplified working with DB on Android. You can read about CROM on my previous post here. But here we will digg into DB model, how to create it good and how to upgrade your schema.
Inspiration
I was working on mobile app, and one requirement was that app should keep user's data.
Caching data is nothing unusual. For example creating YATA (Yet Another Twitter App) also would need this feature.
BTW, YATAPP is very frequent choice made by new Android devs :)
OK, let's take a look what Android offers in terms of Database.
