You need to ask for runtime permission of read phone state. This is included for better security.

code is as follows:-

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

    String IMEI ="";

    if (ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
       ActivityCompat.requestPermissions(getActivity(),
               new String[]{Manifest.permission.READ_PHONE_STATE},
               123);

    }
    int permission = ContextCompat.checkSelfPermission(getContext(),
            Manifest.permission.READ_PHONE_STATE);
    if(permission == PackageManager.PERMISSION_GRANTED){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            IMEI = telephonyManager.getImei();
        }
        else{
            IMEI = telephonyManager.getDeviceId();
        }
    }
