Exception while hitting a URL from android app

Question

I'm getting exception while hitting a url from android app. I have added Internet permission to the app's manifest.

URL url = new URL("www.example.com?query=abcd");
        HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
        urlConnection.connect();
        urlConnection.disconnect();

This is stacktrace of exception

Please, at least do some research about this exception ... similar questions are asked 10 times a day, because so many people just don't know how to do internet search(or just can't learn on example) — Selvin, Apr 04 '16 at 09:25

According to Android developer guide lines NetworkOnMainThreadException is thrown when you perform any network based operation on main thread. So call your webservice in worker thread(eg async task).

For debugging purpose if you want to call webservice on main thread then

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); StrictMode.setThreadPolicy(policy);

But do not use it unless you want just for debugging
