Android SQLite Query, Insert, Update, Delete, Always Need to be On Background Thread?

Question

I currently use Loaders to grab data from my ContentProvider (to enable auto-updating of my Cursors). This approach is straight-forward for Querying the database, though, it seems ill suited for any other DB operation (such as Insert, Update, Delete).

My questions are:

1. Do all SQLite operations need to be on a background thread, or is it safe to do simple operations like Inserting, Updating, or Deleting a single row on the UI thread?
2. What is a nice design patter to ensure all queries go through a background thread? I would like to implement AsyncTask, should I create a SuperTask so to speak that extends AsyncTask and Executes each SQLite operation? (Bonus: Can you provide bare-bones example?)
