I'm writing a small alarm clock application, and I'm currently using SharedPreferences to store the settings for each alarm. I figured this would be more lightweight than using the SQLite Database, but now I'm thinking about writing a small thread-safe wrapper for SharedPreference. Am I being an idiot and should just use the database or would this still be more light-weight than the database?
For something this small, how lightweight it is isn't really relevant. Its a matter of 10 nanoseconds versus 50 nanoseconds (not literally but you get the idea). Just use what is easier and more reliable for your app
