Fix Encryption Key Issue in Android XMPP Application

An Android XMPP application saves encryption keys in an SQL table named 'pubsub_item'. For each user, multiple keys are being saved from each reinstall of the app, however only the latest key is required. The task is to modify this app so that only the latest key gets saved in the database and any previous key overwritten.
