This document discusses how to navigate users from an Assistant app to an Android app. It provides code to:
1. Check if the user's device supports screen output and send a basic card with a link button if so. If not, it checks if another device is available that supports screen output and requests a transfer.
2. Define functions for the welcome intent and handling a new surface.
3. Build a basic card rich response with a link button that will launch the LINE app when clicked, and provide example HTML to redirect to the LINE app after 5 minutes.
