Android – Get List of Users and Profile Name

Introduction

This article will guide you on retrieving a list of users and their profile names on an Android device. We’ll explore different methods and provide code snippets to illustrate the process.

Methods

• Using Android’s AccountManager
• Using Device Policy Manager
• Using the Contacts API

AccountManager

The AccountManager class provides access to user accounts configured on the device. You can use this to get a list of user accounts and their associated profile names.

Code Example

import android.accounts.Account;
import android.accounts.AccountManager;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        AccountManager accountManager = AccountManager.get(this);
        Account[] accounts = accountManager.getAccounts();

        Log.d("AccountManager", "List of accounts:");
        for (Account account : accounts) {
            Log.d("AccountManager", "Name: " + account.name + ", Type: " + account.type);
        }
    }
}

Output

D/AccountManager: List of accounts:
D/AccountManager: Name: user1@gmail.com, Type: com.google
D/AccountManager: Name: user2@example.com, Type: com.example

Device Policy Manager

The Device Policy Manager (DPM) allows you to retrieve a list of user profiles on the device. This method is suitable for scenarios where you need user profiles beyond accounts.

Code Example

import android.app.admin.DevicePolicyManager;
import android.content.ComponentName;
import android.content.Context;
import android.os.Bundle;
import android.util.Log;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        DevicePolicyManager devicePolicyManager = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);
        ComponentName adminComponent = new ComponentName(this, MyDeviceAdminReceiver.class);

        if (devicePolicyManager.isAdminActive(adminComponent)) {
            String[] userIds = devicePolicyManager.getActiveUsers();
            Log.d("DevicePolicyManager", "List of user IDs:");
            for (String userId : userIds) {
                Log.d("DevicePolicyManager", userId);
            }
        } else {
            Log.e("DevicePolicyManager", "Device admin not active.");
        }
    }
}

Output

D/DevicePolicyManager: List of user IDs:
D/DevicePolicyManager: 0
D/DevicePolicyManager: 10

Contacts API

The Contacts API allows you to retrieve contact information, including profile names. You can use this to get a list of user names associated with contacts.

Code Example

import android.content.ContentResolver;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.util.Log;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ContentResolver contentResolver = getContentResolver();
        Uri uri = ContactsContract.Contacts.CONTENT_URI;
        Cursor cursor = contentResolver.query(uri, null, null, null, null);

        Log.d("ContactsAPI", "List of contacts:");
        if (cursor != null) {
            while (cursor.moveToNext()) {
                String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                Log.d("ContactsAPI", "Name: " + displayName);
            }
            cursor.close();
        }
    }
}

Output

D/ContactsAPI: List of contacts:
D/ContactsAPI: Name: User 1
D/ContactsAPI: Name: User 2
