    }
    return deviceUniqueIdentifier;
}

Please use this

manifest file

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

In Java File

 public static String getUniqueIMEIId(Context context) {
    try {
        TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        if (ActivityCompat.checkSelfPermission(context, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return "";
        }
        String imei = telephonyManager.getDeviceId();
        Log.e("imei", "=" + imei);
        if (imei != null && !imei.isEmpty()) {
            return imei;
        } else {
            return android.os.Build.SERIAL;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return "not_found";
}

I'm update my code.Please check now. – Saurabh Vadhva Feb 01 '18 at 07:19
Call requires permission which may be rejected by user: code should explicitly check to see if permission is available (with checkPermission) or explicitly handle a potential SecurityExceptionThis check scans through your code and libraries and looks at the APIs being used, and checks this against the set of permissions required to access those APIs. If the code using those APIs is called at runtime, then the program will crash. Furthermore, for permissions that are revocable (with targetSdkVersion 23), client code must also be prepared to handle the calls throwing an exception if the user... – Shahriyar Aghajani Feb 01 '18 at 07:22
Please replace "android.os.Build.SERIAL" to "IMEI number not found". then check and let me know. – Saurabh Vadhva Feb 01 '18 at 07:25

use: String imei = telephonyManager.getImei(); String serial = android.os.Build.getSerial(); for new versions android sdks (for ex. API 27 which I am using currently) – Dhwanit Aug 13 '19 at 18:09

Try this

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
        // TODO: Consider calling

        return;
    }
    String imei = telephonyManager.getDeviceId();

Add Permission in Manifest.xml

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

public  String getIMEI(final Context context) {
    final TelephonyManager ts =
    (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    return ts.getDeviceId()) ;
}

make sure you have Manifest.permission.READ_PHONE_STATE Permission
