Integrate Google Mobile Ads SDK with AI tools

To optimize Gemini in Android Studio, use an AGENTS.md file in your project. By adding an AGENTS.md file to your project, you provide Gemini with context specific to Google Mobile Ads SDK and improve the output of AI-assisted code generation. For details, see Customize Gemini using AGENTS.md files.

This guide covers optimizing Gemini in Android Studio for Google Mobile Ads SDK.

Before you begin

Before you continue, do the following:

Add AGENTS.md file to your project

Google provides an AGENTS.md file with instructions for Gemini to help you with the following integration steps:

  • Add Google Mobile Ads SDK to your project.
  • Implement banner ads.

To use instructions specific to Google Mobile Ads SDK in AI code assist, follow these steps:

  1. Create a new file named AGENTS.md anywhere in your project's file system.

  2. In your AGENTS.md file, add the following instructions:

# AI Coding Agent Instructions for the Google Mobile Ads SDK

## Integrate the SDK

*   When I ask to integrate the Google Mobile Ads SDK, **always** use the latest
    stable version for `com.google.android.gms:play-services-ads`.
*   After looking up the latest stable version of
    `com.google.android.gms:play-services-ads`, **always** check the project for
    a version catalog to manage dependencies.
*   Make sure the project meets the SDK requirements of `minSdk` 23 or higher
    and `compileSdk` of 35 or higher.
*   **Always** make sure there is a `<metadata>` tag for application ID in the
    project. If it's not there, add it.
*   You MUST initialize the Google Mobile Ads SDK on a background thread, as
    recommended in the Google Mobile Ads SDK v24.0.0 release notes.

## Banner Ads

*   When I ask to implement a banner ad or something similar, without specifying
    a type, **always** follow up to confirm the type of ad.
*   When I ask for an "anchored adaptive" ad, ask me if I want the ad anchored
    to the top or bottom of the screen.
*   When I ask for an "inline" adaptive banner ad, explain that inline adaptive
    ads are used for scrolling content. If my application has no scrollable view
    elements (e.g. `ScrollView` or `List`), default to implement an anchored
    adaptive banner ad.
*   When I ask for a "collapsible" banner ad, create an extra parameter that
    aligns the expanded ad to the `AdView`. Ask me if I want the ad collapsed to
    the top or bottom.
*   When I ask for a "fixed size" banner ad, **always** ask me if I'm sure or
    would I like to implement an anchored adaptive banner ad. Explain why
    anchored adaptive banner ads perform better than fixed size ads.

*   **Mandatory `AdView` Implementation Steps:**
    *   **Always** provide the code for a UI container intended to host the
        `AdView`.
    *   **Always** call `adView.destroy()` to prevent memory leaks.

## Migrate to the GMA Next-Gen SDK

*   When I ask to migrate to the "Next Gen" SDK, **always** use the latest
    stable version for
    `com.google.android.libraries.ads.mobile.sdk:ads-mobile-sdk`.
*   Make sure the project meets the SDK requirements of `minSdk` 24 or higher
    and `compileSdk` of 35 or higher.
*   Replace the `com.google.android.gms:play-services-ads` dependency with the
    Next Gen `com.google.android.libraries.ads.mobile.sdk:ads-mobile-sdk`
    dependency.
*   All `com.google.android.gms.ads.*` import statements must change to
    `com.google.android.libraries.ads.mobile.sdk.*`.
    *   If the change is in a custom event adapter, ask me if I'm sure I want to
        migrate this class before making the change.
*   Preserve the `com.google.android.gms.ads.APPLICATION_ID` `<meta-data>` tag
    in the `AndroidManifest.xml` file if present.
*   YOU MUST analyze the code until all errors have been resolved. Resolve the
    errors by using the APIs from the GMA Next-Gen SDK. Refer to the Android
    documentation.

Prompt Gemini in Agent Mode

After configuring your AGENTS.md file, you can prompt Gemini in Android Studio in Agent Mode.

In Agent Mode, you can use the following example prompts:

Integrate the SDK

Integrate the latest version of the GMA SDK to my project. Refer to the Android
documentation.

Add a banner

Add an anchored adaptive banner ad to the bottom of the screen. Refer to the
Android documentation.
