Google Opens Android to Third-Party AI Agents, Unveils...

Google rewired Android Studio this week, and the headline number is 40. That's how many third-party coding agents developers can now run directly inside the IDE, thanks to a new "Bring Your Own Agent" feature announced at this year's Android Dev Summit. Anthropic's Claude Agent, OpenAI's Codex, and Google's own Antigravity tool all land in a built-in marketplace, accessible through the open Agent Client Protocol.

For years, Android developers were stuck with whatever AI tooling Google decided to ship. That changes with Android Studio Rabbit 2.

The shift extends past the IDE itself. New APIs, including a Gemini Nano 4-powered Agentic API and support for the Model Context Protocol, let developers run agent functions locally on phones and tie app features straight into Google Search and the Gemini app. Google also used the summit to debut hardware: the XREAL AURA, a $1,099 pair of Android XR smart glasses built with XREAL, which projects virtual workspaces and leans on Gemini to read the wearer's surroundings. Together, the announcements point to Google treating agents, not just apps, as the core unit of Android development going forward.

With Android Studio Rabbit 2, Google is launching a "Bring Your Own Agent" (BYOA) feature. Developers are no longer limited to Google's own AI tools. Instead, they can use the open Agent Client Protocol (ACP) to run more than 40 different coding agents directly in the IDE.

Google opens Android development to third-party AI agents and unveils new Gemini APIs - THE DECODER

Why this matters

Google just moved the agent war onto home turf. Letting more than 40 third-party coding agents, including Claude and Codex, into Android Studio is an admission that no single company will own the agentic coding stack, so Google would rather be the platform everyone builds on than the lab everyone compares itself to. For developers, that means less lock-in anxiety and more real competition over which agent actually writes better code, faster.

The Gemini Nano 4 Agentic API matters more. Running agent functions locally through MCP means apps can host interactive agents without round-tripping to a server, which cuts latency and gives founders a cheaper story for shipping agent features at scale. For researchers, it's a useful signal: on-device agentic processing is moving from novelty to infrastructure Google expects third parties to build against.

We'd watch two things from here: how fast those 40-plus agents actually ship meaningful integrations rather than demo-ware, and whether "alpha" on the Nano 4 API turns into something production-ready before competitors catch up on-device.
