Getting Started with Android Management API in Node.js

If a company provides Android devices to its employees for daily tasks, how would it make sure these devices are being used securely? For instance, how can you ensure employees use appropriate passwords, access only the apps they need, and avoid potential security risks?

And it’s not just about regular employees. Think about scenarios where extra-sensitive data is involved—like devices used by high-level executives, or even the Presidents. These devices demand stricter controls and advanced security measures to ensure they’re not just compliant but also safeguarded against any potential threats.

Whether it's enforcing strong passwords, restricting app usage, or adding an extra layer of protection for critical roles, the management of these devices has to be seamless yet comprehensive.

That’s where the Android Management API comes in. It’s a powerful tool designed to simplify the management of Android devices. In this article, we’ll explore how companies can use the Android Management API with Node.js to manage devices programmatically. Whether you're an enterprise admin or a developer building a device management solution, this guide will get you started.

What is the Android Management API?

The Android Management API, provided by Google, lets businesses remotely manage Android devices by enforcing security policies, configuring settings, and even restricting certain device features. It’s built on the principles of simplicity and scalability, allowing enterprises to manage thousands of devices with consistent policies.

Using this API, you can:

Enforce password and security policies.
Restrict app usage to only approved apps.
Lock or wipe devices remotely if they’re lost or stolen.
Configure network settings like Wi-Fi or VPN.

The possibilities are endless, but today we’ll focus on a beginner-friendly approach: setting up the API and performing basic tasks like creating an enterprise and enforcing a simple policy using Node.js.

Common Use Cases for Android Management API

Before we dive into the implementation, let’s look at some real-world scenarios where the Android Management API shines:

Password Enforcement: Companies can enforce password rules like complexity, length, and expiration to enhance device security.
App Management: Restricting app installations to only approved apps or blocking certain apps entirely is a breeze.
Remote Device Control: Enterprises can remotely lock or wipe devices to prevent data leaks in case of theft or employee offboarding.
Network Configuration: Configure corporate Wi-Fi or VPN settings without manual intervention.

Some Example Usecases:

Android device management is used in various scenarios, including:

Employee Devices: Managing corporate-owned devices to enforce policies like app restrictions or secure logins.
Kiosk Devices: Setting up devices for specific tasks, like self-check-in at airports or food delivery terminals.
Loaned Devices: Temporarily configuring devices for events or contractors.
High-Security Devices: Enforcing stricter policies for sensitive use cases, such as executive-level devices or government-issued phones.

While we’ll only touch on a few of these in this article, the API allows for a highly customized and centralized management experience. I will put more advanced content regarding it soon so make sure to subscribe my Newsletter

EMM Console and the Android Management API: How It All Comes Together

To manage Android devices effectively, organizations rely on a structured flow involving the EMM Console, the Android Management API, and the devices themselves. Let’s break this down:

What is the EMM Console?
The Enterprise Mobility Management (EMM) Console is the dashboard where administrators define policies, like app restrictions, password requirements, or device usage modes. It’s the control panel for managing Android devices across the organization.

As a developer, your role depends on the needs of the business. If the organization uses an existing EMM solution, your job may involve integrating the Android Management API and configuring policies. However, if the business requires a tailored solution, you might build a custom EMM Console. This involves developing both the backend (to interact with the Android Management API) and the frontend dashboard for policy management.
The Role of the Android Management API
The API acts as a bridge, translating policies defined in the EMM Console into enforceable rules on devices. It ensures the seamless application of security measures, app restrictions, and other configurations.
Devices
Devices receive these policies and enforce them in real-time. For instance, they restrict unauthorized apps, enforce password requirements, and lock down devices to specific usage scenarios.

High-Level Example

Imagine a sales team needs secure devices:

The admin creates a "Sales Policy" in the EMM Console.
The Android Management API communicates this policy to all devices.
On the devices, only CRM and email apps are accessible, and weak passwords are disallowed.

This flow ensures every device complies with company policies while giving administrators centralized control, whether through an existing EMM or a custom-built solution.

Setting Up Your Project and Environment

Prerequisites

To get started, ensure you have:

Node.js installed on your machine.
A Google Cloud account to enable the API and manage credentials.
Basic familiarity with APIs and JSON formatting.

Step 1: Enable the Android Management API

The Android Management API is not enabled by default in Google Cloud. You need to enable it for your project before making any API calls.

Log in to the Google Cloud Console.
Create a new project or select an existing one.
Navigate to APIs & Services > Library. Search for "Android Management API" and enable it for your project.

This step ensures your project has access to the API’s functionality.

Step 2: Create a Service Account

The service account acts as the identity that your application uses to interact with the Android Management API.

In the Google Cloud Console, navigate to IAM & Admin > Service Accounts.
Click Create Service Account, give it a name, and assign the "Android Management API Admin" role.
Generate a key in JSON format and download it. This file contains sensitive credentials—store it securely, as we’ll use it to authenticate our Node.js application.

Implementing Basic Features with Node.js

Now that your environment is set up, let’s dive into using the API with Node.js. We’ll start with authentication and build up to creating an enterprise and applying a simple policy.

Step 1: Set Up Your Node.js Project

Before writing any code, initialize a Node.js project and install the necessary dependencies:

npm init -y  
npm install googleapis

This creates a new project folder, initializes it with a package.json file, and installs the googleapis library, which we’ll use to interact with the Android Management API.

Step 2: Authenticate with the API

Authentication is a critical first step. We’ll use the downloaded service account key to authenticate our app and obtain a client for API calls.

const { google } = require('googleapis');  
const fs = require('fs');  

// Load service account key  
const auth = new google.auth.GoogleAuth({  
  keyFile: './service-account-key.json', // Path to your key file  
  scopes: ['https://www.googleapis.com/auth/androidmanagement']  
});  

(async () => {  
  const client = await auth.getClient();  
  const androidManagement = google.androidmanagement({ version: 'v1', auth: client });  
  console.log('Authenticated successfully!');  
})();

Here’s what’s happening:

We load the service account key using GoogleAuth.
The scopes define the permissions we’re requesting (in this case, access to the Android Management API).
Finally, we create a client that we’ll use for all API interactions.

Step 3: Create an Enterprise

An enterprise represents your company in the Android Management API. It’s the base entity under which policies and devices are managed.

const enterpriseName = 'MyCompanyEnterprise';  

(async () => {  
  const client = await auth.getClient();  
  const androidManagement = google.androidmanagement({ version: 'v1', auth: client });  

  const response = await androidManagement.enterprises.create({  
    requestBody: {  
      enterpriseDisplayName: enterpriseName,  
      projectId: 'your-google-cloud-project-id'  
    }  
  });  

  console.log('Enterprise created:', response.data);  
})();

This code creates an enterprise and returns its unique ID. Replace your-google-cloud-project-id with your actual project ID.

Step 4: Apply a Basic Policy

Policies allow you to enforce specific rules across devices. Let’s create a simple policy that enforces strong passwords.

const policyName = 'BasicPolicy';  

(async () => {  
  const client = await auth.getClient();  
  const androidManagement = google.androidmanagement({ version: 'v1', auth: client });  

  const response = await androidManagement.enterprises.policies.patch({  
    name: `enterprises/{enterprise-id}/policies/${policyName}`,  
    requestBody: {  
      passwordRequirements: {  
        minimumLength: 8,  
        requireLetters: true,  
        requireNumbers: true  
      }  
    }  
  });  

  console.log('Policy applied:', response.data);  
})();

This code:

Defines a policy that requires passwords to be at least 8 characters long, with both letters and numbers.
Applies the policy to the specified enterprise. Replace {enterprise-id} with the ID obtained in the previous step.

Exploring Advanced Features

While we covered the basics, the Android Management API has much more to offer:

Device Enrollment: Seamlessly onboard new devices into your enterprise.
App Management: Define which apps are allowed, blocked, or required on devices.
Fleet Management: Manage configurations for hundreds or thousands of devices efficiently.

Exploring these features can unlock powerful capabilities for businesses, and the official documentation is a great place to dive deeper.
