UIL Bug #1153.java

@Override

        super.onResume();
        //Register broadcast receiver to receive changes in connectivity
        registerReceiver(brConnectivityChangeReceiver, new IntentFilter(
                "android.net.conn.CONNECTIVITY_CHANGE" //Ideally, put this in the strings.xml file
        ));
    }

private BroadcastReceiver brConnectivityChangeReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            //Get reference to the ConnectivityManager to retrieve network info object
            ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
            //Get Network Info to access current connection type
            NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
            //Check if connected internet type is WiFi or not
            if (networkInfo != null && networkInfo.getType() == ConnectivityManager.TYPE_WIFI)
                ImageLoader.getInstance().displayImage(url, imageView, imageLoadingListener); //Attempt to load image again
            else
                Log.i(TAG, "Don't have Wifi Connection"); //Do nothing here since the user has already been prompted once to turn on wifi
        }
    };
