Meta Wearables Device Access Toolkit for Android

The Meta Wearables Device Access Toolkit enables developers to utilize Meta’s AI glasses to build hands-free wearable experiences into their mobile applications. By integrating this SDK, developers can reliably connect to Meta’s AI glasses and leverage capabilities like video streaming and photo capture.

The Wearables Device Access Toolkit is in developer preview. Developers can access our SDK and documentation, test on supported AI glasses, and create organizations and release channels to share with test users.

Including the SDK in your project

You can add the Wearables Device Access Toolkit to your Gradle project by following the steps below. You will need to provide a personal access token (classic) with at least read:packages scope as an environment variable named GITHUB_TOKEN or by adding it as a property named github_token in your local.properties file. See SDK for Android setup for more details.

1. Add the repository definition to settings.gradle.kts

val localProperties =
    Properties().apply {
        val localPropertiesPath = rootDir.toPath() / "local.properties"
        if (localPropertiesPath.exists()) {
            load(localPropertiesPath.inputStream())
        }
    }

dependencyResolutionManagement {
    ...
    repositories {
        ...
        maven {
            url = uri("https://maven.pkg.github.com/facebook/meta-wearables-dat-android")
            credentials {
                username = "" // not needed
                password = System.getenv("GITHUB_TOKEN") ?: localProperties.getProperty("github_token")
            }
        }
    }
}

2. Declare the Wearables Device Access Toolkit artifacts in libs.versions.toml

Check the available versions in GitHub Packages.

[versions]
mwdat = "0.7.0"

[libraries]
mwdat-core = { group = "com.meta.wearable", name = "mwdat-core", version.ref = "mwdat" }
mwdat-camera = { group = "com.meta.wearable", name = "mwdat-camera", version.ref = "mwdat" }
mwdat-mockdevice = { group = "com.meta.wearable", name = "mwdat-mockdevice", version.ref = "mwdat" }

3. Add the required components as dependencies in your app’s build.gradle.kts

dependencies {
    implementation(libs.mwdat.core)
    implementation(libs.mwdat.camera)
    implementation(libs.mwdat.mockdevice)
}

Developer Terms

• By using the Wearables Device Access Toolkit, you agree to our Meta Wearables Developer Terms, including our Acceptable Use Policy.
• By enabling Meta integrations, including through this SDK, Meta may collect information about how users’ Meta devices communicate with your app. Meta will use this information collected in accordance with our Privacy Policy.
• You may limit Meta’s access to data from users’ devices by following the instructions below.

Opting out of data collection

To configure analytics settings in your Meta Wearables DAT Android app, add the following <meta-data> element to your app’s AndroidManifest.xml file within the <application> element:

<meta-data
    android:name="com.meta.wearable.mwdat.ANALYTICS_OPT_OUT"
    android:value="true"
    />

Default behavior: If the ANALYTICS_OPT_OUT metadata is missing or set to false, analytics are enabled (i.e., you are not opting out). Set to true to disable data collection.

Note: In other words, this setting controls whether or not you’re opting out of analytics:

• true = Opt out (analytics disabled)
• false = Opt in (analytics enabled)

Complete example:

<application
    android:name=".MyApplication"
    android:label="MyApp"
    android:icon="@mipmap/app_launcher">

    <!-- Required: Your application ID from Wearables Developer Center -->
    <meta-data
        android:name="com.meta.wearable.mwdat.APPLICATION_ID"
        android:value="your_app_id_here"
        />

    <!-- Optional: Disable analytics -->
    <meta-data
        android:name="com.meta.wearable.mwdat.ANALYTICS_OPT_OUT"
        android:value="true"
        />

    <!-- Your activities and other components -->
</application>

AI-Assisted Development

This repository ships one public DAT knowledge base in two first-class formats:

Tool	Public artifact	Recommended setup
Claude Code	.claude-plugin/marketplace.json + plugins/mwdat-android/.claude-plugin/plugin.json	Add this GitHub repo as a marketplace, then install mwdat-android
Codex	plugins/mwdat-android/.codex-plugin/plugin.json	Install the plugin from a cloned checkout of this repo
GitHub Copilot	.github/copilot-instructions.md	Auto-loaded by Copilot in VS Code
Cursor	.cursor/rules/*.mdc	Auto-loaded with glob-based triggers
AGENTS.md-compatible tools	AGENTS.md	Portable fallback for agents that read AGENTS.md
MCP-compatible editors	https://mcp.facebook.com/wearables_dat	Connect as a remote HTTP MCP server

Claude and Codex install from the plugin payload under plugins/. Copilot, Cursor, and AGENTS.md readers use the native file-based artifacts at repo root.

Claude Code

claude plugin marketplace add facebook/meta-wearables-dat-android
claude plugin install mwdat-android@mwdat-android-marketplace

Or use the helper script:

./install-skills.sh claude

Codex

git clone https://github.com/facebook/meta-wearables-dat-android.git
cd meta-wearables-dat-android
codex plugin install ./plugins/mwdat-android

Or use the helper script:

./install-skills.sh codex

Other tool installs

Use the installer when you want the repo-native file surfaces for other tools:

./install-skills.sh copilot   # .github/copilot-instructions.md
./install-skills.sh cursor    # .cursor/rules/*.mdc
./install-skills.sh agents    # AGENTS.md
./install-skills.sh all       # Claude/Codex when available, plus Copilot/Cursor/AGENTS.md

Or run the helper remotely:

curl -sL https://raw.githubusercontent.com/facebook/meta-wearables-dat-android/main/install-skills.sh | bash
