Uh... not sure I understand. There isn't really swapping to the database, SQLite just opens a file and commits changes to it as you perform transactions on it. Also, you can't put arbitrary objects into the database, for the same kinds of reasons -- you need some way to turn the in-memory representation of an objected into a flattened byte stream. > Pass by reference could always have another layer and this layer would > either get the object from persitance state or from memory if the > object is alive already.

We are killing -processes-. All of the activities in your application (as well as all of its other code) are running in the same process. Once that process is killed, everything in it goes away. > O.S has decided to killing the activity to release the resources and > more is available for other foreground activities.
