This roundtable invites a collaborative exploration around what App Functions are, and what they might be for. Kick-Off Questions What are some use-cases where you might use App Functions within your own app? How might a permission model work that allows you to call other apps' functions?

How fundamentally does the App Functions feature alter the existing Android inter-process communication (IPC) model (e.g., Intents, Services, Content Providers)? Are they a replacement or an extension? How would you go about keeping track of changes to features like this? What tools and resources would you reach for? How can you try new tech out?
