Google makes Android Studio’s BYOA support stable in Rabbit 2

Google announced Android Studio Rabbit 2 on October 28, 2026, with stable Bring Your Own Agent (BYOA) support. Developers can connect more than 40 coding agents that use the Agent Client Protocol (ACP), including Claude Agent, Codex, Junie, and Google Antigravity. The integration brings those agents into Android Studio’s development workflow; the agents remain offerings from their respective providers. (Android Developers)

How to select an agent in Android Studio

Open the agent window and choose an agent, or go to Settings > Tools > AI > Agents to browse and install one. After authenticating, submit a prompt. You can install multiple agents and switch between them.

Google says connected agents can use Android Studio tools including the Android Emulator, build systems, and Logcat. They can also draw on project structure and build context, symbol resolution, and Compose Preview rendering. That gives an agent access to Android-specific development tools from inside the IDE.

Android Studio also includes skills for focused workflows, such as migrating XML Views to Jetpack Compose, upgrading to AGP 9, creating adaptive layouts, and integrating CameraX or Firebase. Its Change Review can analyze agent changes, pending commits, or committed changes; developers can start a review with /review and ask an agent to address issues it identifies.

Android CLI gives developers a separate route

Android CLI is Google’s command-line toolchain for Android development. Google offers official CLI plugins for Claude Code and Codex, while its Android plugin for Google Antigravity brings together Android CLI, Android Skills, and Android knowledge resources. This route equips an external agent workflow with Android tools; BYOA is the option for selecting a compatible agent inside Android Studio. (Android Developers’ Android Dev Summit roundup)

Google also lists privacy, audit, and administrator controls specifically for Gemini Enterprise in Android Studio. Those controls are scoped to Gemini Enterprise. (Android Developers)

Related Android features have different release stages

Google assigns separate maturity labels to agent-related tools and APIs. Rabbit 2’s BYOA support is stable; the other features below are at earlier stages. (Android Developers; Android Developers’ Android Dev Summit roundup; Android Developers)

What Google’s performance figures cover

Google reports that, in its internal testing, agents using android preview completed UI tasks 77% faster while using up to three times fewer tokens. That result concerns agents using the preview-rendering command for UI tasks. (Android Developers’ Android Dev Summit roundup)

For a separate LeakCanary workflow, Google says its most capable models ran the task almost twice as fast and used up to 25% fewer tokens with Android CLI than without it. The figures describe that specific workflow and comparison. (Android Developers’ Android Dev Summit roundup)

Android Bench 2.0 evaluates models and agent harnesses on long-running Android development tasks, such as migrating an app’s UI or building one from mockups. Google says it assesses whether a solution works, along with cost and time, rather than checking compilation alone. (Android Developers’ Android Dev Summit roundup)
