set this permission in manifeast:

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

Now use this to get unique no:

TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
  telephonyManager.getDeviceId();

getDeviceId is deprecated you can use this method to get the device IMEI

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        IMEINumber = telephonyMgr.getImei();
    } else {
        IMEINumber = telephonyMgr.getDeviceId();
    }

You can use below which is preferrable which has the least chances of reset.

private String android_id = Secure.getString(getContext().getContentResolver(),
                                                        Secure.ANDROID_ID);

Please refer THIS from which you can decide the preferable one.

Use the below code:

 public String androidId;

 androidId = String
                .format("%16s", Settings.Secure.getString(getApplicationContext().getContentResolver(), Settings.Secure.ANDROID_ID))
                .replace(' ', '0');

As per the latest release in Android 10, Restriction on non-resettable device identifiers. PPS must have the READ_PRIVILEGED_PHONE_STATE privileged permission in order to access the device's non-resettable identifiers, which include both IMEI and serial number.

"READ_PRIVILEGE_PHONE_STATE" is only accessible by The best practices suggest that you should "Avoid using hardware identifiers." for unique identifiers. You can use an instance id from firebase e.g FirebaseInstanceId.getInstance().getId();.

Or you can go with this also,

String deviceId = android.provider.Settings.Secure.getString(
                    context.getContentResolver(), android.provider.Settings.Secure.ANDROID_ID);
