Insert, Update and Delete from a SQLite Database (Android)

I already have a SQLite Database setup which I am using as cache for the Android application. The application does a HTTP Request and gets back a List of objects which I can insert into the db. After the first request, if I do anymore requests, how do all of the following in a better way:

1) insert all new objects from the list

2) update all objects that were already in the db

3) delete all rows that were not there in the latest list of objects.

I know that options 1 and 2 can be done using the "INSERT OR UPDATE" query. How can I manage the 3rd option efficiently?

Right now my approach is to delete all from table and then insert all. But that isn't very efficient. Any ideas how to improve it?
