How to Use Gemini 4 Argon in Android Studio Canary

Android developers gained access to Gemini 4 Argon on 13 October 2026. Google’s frontier model handles long-horizon coding tasks, including multi-file refactors, build diagnosis, and Jetpack Compose UI generation. Google AI Ultra subscribers can use it through Google Antigravity inside the latest Android Studio Canary.

This guide walks through the official setup path from the Android Developers Blog. It covers prerequisites, login, plugin installation, and practical prompts that trigger agentic workflows.

Prerequisites

You need an active Google AI Ultra subscription to access Argon through Antigravity in Android Studio Canary. Paid Gemini API tier users can call the model in stable Android Studio, but the Canary + Antigravity path unlocks the full agentic harness described by Google.

Download the latest Android Studio Canary from the Android Studio preview channel. Install or update the Antigravity desktop app or CLI from antigravity.google. Confirm your account shows Ultra benefits.

Google recommends the official Android CLI plugin so the agent can run Gradle tasks, capture compiler output, and invoke device tools without leaving the IDE.

Step 1: Open Android Studio Canary and sign in

Launch Android Studio Canary. Open or create any Android project. Click the Agent tool window (or View > Tool Windows > Agent).

Select the Google Antigravity agent from the available options. Sign in with the Google account that holds your AI Ultra subscription. The agent window should confirm the connection and list available models, including Gemini 4 Argon.

If the agent does not appear, check that you are on the Canary channel and that BYOA support is enabled. Restart the IDE after signing in.

Step 2: Enable the Android CLI plugin

The plugin connects Antigravity to local Android build tools. Two paths exist.

In the Antigravity Desktop app: open Settings > Customizations > Build With Google Plugins (or the Plugin Marketplace). Locate android-cli-plugin and toggle it to Enabled.

From the terminal (Antigravity CLI):

agy plugin install android-cli-plugin

After installation, run android init in your project directory if you use a terminal-based agent. This registers skills and tool access for the current project.

Once active, the agent can read Gradle logs, run builds, and apply fixes without manual copy-paste.

Step 3: Run a self-healing build task

Argon is trained to maintain hypotheses across edit rounds and use AST awareness when diagnosing failures. Give it a failing build and let the closed-loop process work.

Example prompt in the Agent window:

“The current Gradle sync fails with a Kotlin version mismatch. Capture the compiler output, identify the root cause, update the version catalog and build files, then re-run the build until it succeeds.”

The agent should pull error streams from the Gradle daemon, propose targeted changes, apply them, and verify. Review the diff before accepting large edits. Keep the conversation in one thread so context (including prior thinking) remains available.

Step 4: Generate Compose UI with shaders

Argon can emit production-ready Jetpack Compose, including AGSL shaders for effects such as frosted glass or dynamic lighting. These run on the GPU and pair with 120 FPS animations.

Try:

“Create a Compose screen with a frosted-glass bottom bar using an AGSL shader. Include a Material 3 top app bar, a LazyColumn of sample cards, and a floating action button. Match the existing theme colors.”

Inspect the generated Modifier.graphicsLayer blocks and shader code. Test on a physical device or emulator running a recent API level. Adjust density and color schemes in a follow-up prompt if the result needs refinement.

For comparison against other models on long-horizon Android work, see the guide to Android Bench 2.0 long-horizon tasks.

Tips for better results

• State the goal and the verification step in one prompt. “Fix the build and confirm the unit tests pass” works better than open-ended requests.
• Use medium thinking for most coding; switch to high only for architecture or multi-module refactors.
• Keep API keys and secrets out of prompts. Prefer local files or environment variables the agent can reference.
• Enable project context sharing so the agent sees your module structure and dependencies.
• After major changes, run the full test suite yourself. Agents reduce cycle time but do not replace final review.
• Monitor usage. Introductory Gemini API pricing ends 30 November 2026; Ultra plan limits differ.

What this setup does not replace

Stable Android Studio still supports Argon through a paid Gemini API key for completion and simpler agent tasks. Firebase AI Logic can call the same model from your app code at runtime. The Canary + Antigravity path is specifically for interactive, multi-step engineering inside the IDE.

Conclusion

Gemini 4 Argon is available today for Ultra subscribers inside Android Studio Canary via Antigravity. Install the Canary build, sign in to the agent, enable the Android CLI plugin, and start with a self-healing build or Compose generation task. Official documentation remains the source for model limits and safety notes.
