Android is moving from simple chatbots to proactive on-device agents that can see your screen and act across apps.
A leaked Android app, COSMO, briefly shipped by Google, bundles a local Gemini Nano model and uses accessibility to watch activity and suggest actions — drafts, calendar events, even browser tasks. That signals agents that run offline but escalate to cloud models when needed.
On the other side, Apple’s agent plans point to hosting autonomous agents in the App Store with tighter privacy controls and deeper Siri-to-app hooks.
Developers are already prototyping screen-watching helpers, like this screen-watching helper that validates tasks by reading UI state.
On-device agents rewire data flow: more decisions at the edge, fewer server round-trips, and new privacy boundaries.
Cross-app actions require auditable permissions and intent-driven APIs, not brittle UI automation.
-
terminal
Build a small Android proof with accessibility-driven actions and a Nano-class model; measure latency, battery, and offline accuracy.
-
terminal
Trace agent-initiated flows end-to-end; verify consent prompts, least-privilege scopes, logging, and rollback paths.
Legacy codebase integration strategies...
- 01.
Wrap agent access behind feature flags and per-tenant policy; scrub PII when screen-reading triggers server calls.
- 02.
Map legacy flows to Intents/App Intents to avoid selectors and fragile UI scripting.
Fresh architecture paradigms...
- 01.
Expose idempotent, event-driven "skills" with narrow scopes and signed requests so agents can call them safely.
- 02.
Plan hybrid execution: light local checks, server escalation for heavy tasks with quotas and circuit breakers.
