Strategy to handle Nearby Messages API - Android

I am currently working on an messaging application for Android that communicates with other devices using Nearby Messages API. Since this is the first time that I work with this API, I would like to know if there is a pattern or strategy to handle the connections.

For instance, when the user changes the activity (e.g. opens a new conversation), I would like to keep the connection active, so I would like to work with a Connection Manager or something to keep listening and parsing the messages.
