Overview

Google marked Android Dev Summit on October 28 with a set of developer-tooling releases built around coding agents. According to the Android Developers Blog, Android Studio Rabbit 2 is now stable, and its Bring Your Own Agent (BYOA) feature lets developers choose agents including Claude Agent, Codex from OpenAI, Junie and Google Antigravity inside the IDE. The same day, Google’s summit roundup described new Android CLI commands for testing on remote physical devices and rendering Compose previews. On November 2, 9to5Google reported that Google also announced a Quick Share SDK for Android and iOS apps, due in the first half of 2027.

What Shipped in Android Studio

Google says Rabbit 2 is “now stable and ready for you to use in production” and lists Bring Your Own Agent, new XR Emulator features, a LeakCanary update, a new agent skills manager tool and AI code review among its features, per the Rabbit 2 announcement. The developer-tools roundup says Android Studio now supports over 40 ACP-compatible coding agents through BYOA and the open Agent Client Protocol (ACP), and that agents get access to project structure and build, symbol resolution, Compose Preview rendering, the Emulator and Logcat.

Two review-related features are described in the same roundup. Change Review starts a review session from pending agent changes or the Git changes window and generates a report of potential issues; it can also be invoked with the /review command from the agent tool window. A Migration Assistant for moving XML Views to Jetpack Compose is, according to Google, “available in the latest version of Android Studio Canary”, so it is not part of the stable Rabbit 2 release.

Android CLI Additions

Google says it launched Android CLI earlier this year as a tool-first interface for agents; the Herald’s earlier coverage of the Android Studio I/O Edition also described Android CLI. The summit roundup lists these additions:

  • android device remote provisions a real physical device from a secure Google device lab, so an agent or CI pipeline can install and test an app as it would on a local device connected over adb.
  • android preview renders Compose Previews without an emulator or the IDE. Google says that in its internal testing, agents that used it completed UI tasks 77% faster while using up to 3x fewer tokens. These are Google’s figures and the roundup does not publish the test setup.
  • android analyze scores how well R8 shrinks, optimizes and obfuscates an APK or app bundle, with JSON output for CI.
  • Android CLI is now available as an official agent plugin for Claude and Codex, alongside an updated plugin for Google Antigravity.

Google also introduced Lightbuild, which it calls an early preview of a declarative, agent-ready build experience in which build configuration is a strict YAML schema. The company recommends trying it with new or experimental projects “while continuing to use Gradle and AGP for production apps”.

Platform and Jetpack Announcements

In its Dev Summit announcement post, Google lists several API stages:

  • Navigation 3 1.2 is stable, with deep links support and richer Predictive back handling.
  • AppFunctions, which Google describes as Android’s unified tool calling layer, is in beta.
  • A2UI for Jetpack Compose, which lets agents respond with interactive UI built from an app’s own components, is in alpha.
  • The ML Kit Agentic API, built on Gemini Nano 4, is in alpha.
  • Compose 1.13 is described as an “upcoming” stable release that moves Grid and Flexbox adaptive layouts to stable.
  • Core Jetpack XR SDK libraries are stable.

Quick Share SDK and Connected Apps

Abner Li of 9to5Google reported that the Quick Share SDK is coming in the first half of 2027 and will let developers add file sharing directly in their apps instead of sending users to the system Share sheet. Google’s listed capabilities include end-to-end encrypted transfer, automatic hotspot creation, Wi-Fi Direct on supported devices and offline operation, and a Quick Share iOS SDK will also be offered.

Separately, 9to5Google reported on October 28 that Google announced a Connected Apps Platform for bringing third-party services into Gemini and Search. Developers need a cloud-hosted MCP server or an Android MCP using the AppFunctions APIs, and register through a new Google Connected Console. Google is opening preview access in phases over the coming months, per the same report.

What We Don’t Know

  • Google’s posts give no release date for the stable Compose 1.13 release, which they describe as upcoming.
  • Google’s 77% and 3x figures for android preview come from internal testing, with no methodology provided in the roundup.
  • The roundup says the LeakCanary subcommand for Android CLI is “coming soon” and that Fix with AI for memory leaks is in the Canary build, so neither is part of the stable release.
  • No sources cited here give a more specific Quick Share SDK date than the first half of 2027.
