是的，Android管理API确实支持工作负载身份联合以从AWS Lambda进行调用。以下是一个示例Lambda函数代码，您可以使用它来从Android管理API进行调用：

import google.auth
from google.auth.transport.requests import Request
from google.oauth2 import service_account
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError

def android_api_call():
  # Enter your own credentials file path
  credentials = service_account.Credentials.from_service_account_file('/path/to/credentials.json')
  if credentials.expired and credentials.refresh_token:
    credentials.refresh(Request())

  androidmanage = build('androidmanagement', 'v1', credentials=credentials)

  try:
    # Enter your own enterprise and policy ID below
    res = androidmanage.enterprises().policies().get(enterpriseId='your-enterprise-id', policyId='your-policy-id').execute()
    return res
  except HttpError as error:
    print(f'An error occurred: {error}')
    return None

请注意，您需要使用自己的凭据文件路径和企业/策略ID。您可以根据需要调整函数以执行特定任务。
