How to deal with the error "Hostname was not verified" in android

Question

I have been trying to test internet connection by connecting to the server https://mobile.twitter.com/.

For that reason, I have used an AsyncTask as follow:

class CheckInternetConnection extends AsyncTask<Void, Void, Boolean>{
        @Override
        protected void onPostExecute(Boolean result){
            if(result)
                //do stuff
            else
                //do stuff
        }
        @Override
        protected Boolean doInBackground(Void... params) {
            try {
                HttpURLConnection urlc = (HttpURLConnection) (new URL("https://mobile.twitter.com/").openConnection());
                urlc.setConnectTimeout(1500); 
                urlc.connect();
                return (urlc.getResponseCode() == 200);
            } catch (IOException e) {
                Log.e(LOG_TAG, "Error checking internet connection", e);
            }
            return false;
        }
    }

Well the problem is that I get the error

How can I verify the hostname?

Most likely, the site uses a certificate that is not trusted by Android. This answer may help if you want to install the missing root certificate yourself: How to install trusted CA certificate on Android device?
