Android has become increasingly restrictive in providing access to certain device identifiers like IMEI and serial number for privacy and security reasons.

Device Fingerprinting is something we can do. We can create a device fingerprint by collecting various device attributes such as device model, OS version, Build ID (a unique identifier for the software build running on the device. It includes information about the Android version and build date.), and available sensors. This can provide a reasonably unique identifier for each device within your organization.

Here is the code

activity_main.xml

<?xml version = "1.0" encoding = "utf-8"?>
<LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"
    xmlns:app = "http://schemas.android.com/apk/res-auto"
    xmlns:tools = "http://schemas.android.com/tools"
    android:layout_width = "match_parent"
    android:gravity = "center"
    android:layout_height = "match_parent"
    tools:context = ".MainActivity">
    <TextView
        android:id = "@+id/text"
        android:textSize = "30sp"
        android:layout_width = "match_parent"
        android:layout_height = "match_parent" />
</LinearLayout>

MainActivity.java

import android.content.pm.PackageManager;
import android.os.Build;
import android.os.Bundle;
import android.widget.TextView;
import android.Manifest;
import androidx.annotation.RequiresApi;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;


public class MainActivity extends AppCompatActivity {

    TextView textView;
    @RequiresApi(api = Build.VERSION_CODES.P)

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

        textView = findViewById(R.id.text);
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE)
                != PackageManager.PERMISSION_GRANTED) {

            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.READ_PHONE_STATE}, 101);
        }

    }

    @RequiresApi(api = Build.VERSION_CODES.O)
    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
            case 101:
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
                    return;
                }
                textView.setText(Build.FINGERPRINT);
            } else {
                //not granted
            }
            break;
            default:
                super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }

    @RequiresApi(api = Build.VERSION_CODES.O)
    @Override
    protected void onResume() {
        super.onResume();
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE)
                != PackageManager.PERMISSION_GRANTED) {
            return;
        }
        textView.setText(Build.FINGERPRINT);
    }
}

Add these permissions to the manifest

 <uses-permission android:name = "android.permission.INTERNET"/>
 <uses-permission android:name = "android.permission.READ_PHONE_STATE" />

I hope it helps!
