Set Up Gemini 4 Argon with Android CLI Plugin

Gemini 4 Argon reached Android developers on October 13, 2026. The model handles long-horizon coding tasks, self-corrects builds, and produces production-ready Jetpack Compose code. One of the most useful connections is the official Android CLI plugin, which links Argon to local Android tools.

This guide shows how to install and enable the plugin so Argon can run Gradle builds, manage emulators, and execute Android-specific skills. The steps come from the Android Developers Blog post published the same day as the model launch.

If you already use Antigravity for other work, the plugin adds Android capabilities without changing your existing workflow. See our related post on Gemini 4 Argon in Antigravity for the base setup.

What the Android CLI plugin does

The plugin is the engine that connects an agent to local Android tooling. It lets Argon run programmatic commands for common tasks and load custom developer skills. With the plugin active, Argon can capture error streams from Gradle daemons and the Kotlin compiler, then iterate until a build succeeds.

Google describes this as closed-loop build self-correction. The model maintains a consistent hypothesis across successive rounds of editing so it addresses the root cause of failures rather than applying surface patches.

The same plugin also unlocks AGSL shader generation inside Compose modifiers. Argon can write production-ready GPU shaders for frosted glass, dynamic lighting, and ripple effects that run at 120 FPS alongside fluid animations.

Access requirements

You need one of two paths:

• Google AI Ultra subscription for Antigravity desktop or CLI access to Gemini 4 Argon.
• Paid tier of the Gemini API for use inside Android Studio.

Introductory pricing is $2 per million input tokens and $10 per million output tokens through November 30, 2026. After that date the rates rise to $4 and $20. Cached input tokens stay at a 95 percent discount.

Update Antigravity to the latest version before you start. The plugin is distributed through Antigravity’s own marketplace and CLI, not through the Play Store or Android Studio’s standard plugin manager.

Enable the plugin in the desktop app

Open the Antigravity desktop app on macOS, Windows, Linux, or Googlebook. Go to Settings, then Customizations, then Build With Google Plugins. You may also see this section labeled Antigravity Plugin Marketplace depending on the exact build.

Locate android-cli-plugin in the list and toggle it to Enabled. Restart the app if the toggle does not take effect immediately. Once enabled, Argon can call Android CLI commands when it decides they are relevant to the task.

In Android Studio Canary, the path is different. Open the agent tool window and log in with the Google account that holds your Ultra subscription. This surfaces Antigravity agentic workflows alongside the editor without leaving the IDE.

Install via the terminal

If you prefer the command line, run the following inside a terminal where the Antigravity CLI is already available:

agy plugin install android-cli-plugin

For any terminal agent that uses Android CLI directly, run:

android init

The init command registers the plugin and skills so the agent can discover them. After installation, verify by asking Argon to list available Android skills or to create a simple emulator.

Start an agentic Android task

Open a project or create a new one. Give Argon a concrete goal that requires local tooling:

“Create a new Jetpack Compose project with a single screen that shows a live clock. Use the Android CLI to create an emulator, build the project, and install the APK on the emulator. Fix any build errors automatically until the app launches.”

Argon plans the steps, writes the Compose code, invokes the plugin for emulator and build commands, and iterates on compiler output. You stay in control: approve or reject each terminal action if your agent settings require confirmation.

The same flow works for larger tasks such as migrating an existing View-based screen to Compose or adding AGSL shaders to an animation. Because Argon can read Gradle and Kotlin logs directly, it recovers from common dependency and API-level mismatches without manual intervention.

Tips for reliable results

Set the thinking level to high for multi-step Android work. Medium is the default and works for smaller changes, but high improves root-cause diagnosis on build failures.

Keep the local Android SDK and command-line tools up to date. The plugin relies on the same binaries you would use manually, so outdated tools produce the same errors the agent then has to solve.

Start with a small project if this is your first time. Once the plugin successfully creates an emulator and installs an APK, move to an existing codebase. Large monorepos benefit from the same self-healing loop, but the first run takes longer while Argon maps the project structure.

Monitor token usage. Long-horizon tasks that include multiple build cycles consume more output tokens. The introductory pricing window ends November 30, so check your Cloud billing dashboard before running overnight jobs.

Conclusion

The Android CLI plugin turns Gemini 4 Argon into a practical agent for local Android development. It supplies the missing link between the model’s reasoning and the Gradle, emulator, and skill surfaces you already use.

Enable the plugin in Antigravity desktop, Android Studio Canary, or the CLI, then give Argon a bounded goal that includes a build or emulator step. The self-correction loop handles the rest. For the broader Antigravity setup, start with our Gemini 4 Argon Antigravity guide.
