Permissions & Registration (Android)

Register your app with Meta AI, then request the device permissions it needs.

The DAT SDK separates two steps:

1. Registration: The user connects your app to Meta AI.
2. Device permissions: After registration, your app requests capabilities such as camera access.

Both flows depend on the Meta AI app being installed on the phone.

Start registration

Wearables.startRegistration(activity)

Observe registration state:

lifecycleScope.launch {
    Wearables.registrationState.collect { state ->
        // Update your registration UI
    }
}

To unregister:

Wearables.startUnregistration(activity)

Check permission status

checkPermissionStatus(...) is a suspend API that returns a DatResult.

lifecycleScope.launch {
    Wearables.checkPermissionStatus(Permission.CAMERA)
        .onSuccess { status ->
            if (status == PermissionStatus.Granted) {
                startStreaming()
            }
        }
        .onFailure { error, _ ->
            showPermissionError(error.description)
        }
}

Request a permission

Use Wearables.RequestPermissionContract() with the Activity Result API:

private val permissionLauncher =
    registerForActivityResult(Wearables.RequestPermissionContract()) { result ->
        result.onSuccess { status ->
            if (status == PermissionStatus.Granted) {
                startStreaming()
            }
        }.onFailure { error, _ ->
            showPermissionError(error.description)
        }
    }

fun requestCameraPermission() {
    permissionLauncher.launch(Permission.CAMERA)
}

Users can allow once or allow always through the Meta AI flow.

Developer Mode vs production

Mode	Registration behavior
Developer Mode	Use mwdat_application_id = 0 and mwdat_client_token = 0 manifest placeholders for local development
Production	Use the application ID and client token assigned in the Wearables Developer Center

For development builds, enable Developer Mode in the Meta AI app before testing registration and permissions.
