Android 17 - Android becomes an intelligence system

Hi everyone!

Android 17 puts apps closer to the agent layer.

With AppFunctions, an app can expose its own actions as local tools for Android MCP. @Gemini and other assistants can discover those actions and run workflows with access to the app’s local state.

The UI still matters, but the app’s core capabilities can now become callable system-level tools.

It also changes the baseline for app design. Developers now have to assume their apps may run across phones, tablets, foldables, desktop windows, floating bubbles, and handoff surfaces, and @Google is pushing Compose as the default way to build for that world.

The release notes I read first are always the security ones. An OS deployed at this scale is its own attack surface, so the boring hardening work matters more than the headline features, glad to see privacy controls strengthened.

Thant Awesome! Can't wait to try it

AppFunctions and Android MCP are the most interesting parts here. If apps can expose real local actions to assistants, Android starts feeling less like a launcher and more like an agent-ready platform.

the AppFunctions story is interesting but feels like it'll fragment badly in practice - every app defining its own tools means discoverability just becomes chaos at scale. iOS shortcuts went through this exact problem and it never really resolved. also the multi-surface adaptive layout thing has been 'coming soon' since the first foldables launched. show me one concrete use case that only works because of this specific architecture and i'll be more convinced
