Is it possible to store user defined objects in a SQLite database from Android? For example: I am creating one class and I want to store that class object in the database. Is it possible? If it is, how to proceed? On the Blackberry platform, I am able to store objects directly in persistent objects. Is it possible to do this with SQLite and Android?

You'll need to be able to serialize your object into a byte stream and then recreate your object from a byte stream. Then, just store that byte stream in your db.
One option is to use an O/R mapper like SQLObject. It will do most of the plumbing to persist the Python object to a database, and it supports SQLite.
The Android SDK provides dedicated APIs that allow developers to use SQLite databases in their applications. The SQLite files are generally stored on the internal storage under /data/data/<packageName>/databases. However, there are no restrictions on creating databases elsewhere.

EDIT: Read this article to learn about serialization in Java. It caters to the subject in a much better way than I would be able to by just giving some code snippets.

Instead of storing them in SQLite why not store them in db4o, which is specifically designed for storing objects. A simple tutorial for sotring objects using db4o.
