Question

I have a todo list type application that stores all of the note data in a sqlite3 database. Each activity in the application needs access to the database to edit different

In my opinion, the Content Provider is complicated and if you are not sharing with activities that are not your own, you don't need it. Therefore, I suggest you use a singleton class first. Then if you have more time or need it, go for the Content Provider.

I've used a singleton successfully for 6 months without much difficulty. (I was careful to really make it a singleton though, only one instance that loads the data once)

Singleton

• Advantage: Easy to implement
• Advantage: because I used a common instance, I could implement caching easily and hence make the application not have to do to the database as often
• Disadvantage:can't share your data with external Activities

Content Provider

• Advantage: You can share your data with external Activities
• Advantage: You can integrate with the Search API
• Disadvantage: Complicated, need to represent your data in a different way
• Disadvantage: Yet another Android API to spend time learning
