        super.onPostExecute(result);
        if (result != null);

    }
}

do you want to change image in your imageView according to if else conditions. — ELITE, Mar 03 '16 at 02:42
change return type of `AsyncTask` to boolean or anything else than `ImageVIew`. and check same condition in `onPostExecute` method and change image accordingly.. — ELITE, Mar 03 '16 at 02:51

Change defination of AsyncTask<ImageView, Void, ImageView> to AsyncTask<Void, Void, String> and change methods accordingly

protected String doInBackground(Void... params) {
    if (m_iNetworkType == cm.TYPE_WIFI) {
        return "wifi";
    } else if (m_iNetworkType == cm.TYPE_ETHERNET) {
        return "ethernet";
    } else {
        return null;
    }
}

and check condition in

@Override
protected void onPostExecute(String result) {
    super.onPostExecute(result);
    if (result != null) {
        if("ethernet".equals(result)) {
            ethernet.setImageResource(R.drawable.ethernetimage);
        } else if("wifi".equals(result)) {
            ethernet.setVisibility(View.INVISIBLE);
        }
    } else {
        ethernet.setVisibility(View.INVISIBLE);
    }
}

add question. recently, new EthernetImage().execute() call on onresume() I want without changing the screen, when the network changes, change the image. I think create receiver class. is it right? – Mar 03 '16 at 06:49
Yes, you have to create `BroadcastReceiver` to check if network state changed and is online, and then change image in image view. – ELITE Mar 03 '16 at 06:56
