HTTP url connection Android

Question

I am having trouble getting my app to open a connection to the URL that is a JSON file online. I followed guidelines how out to get the inBackground thread to fetch the URL, though when I call .connect() on that URL it seems to return out of the inBackground function because I tested just having a String that would be modified and displayed as a Toast, and modifying the String right after httpConn.connect() caused no change at all. I made sure my permissions were right in the manifest, but perhaps there is something small I am overlooking.

protected String doInBackground(URL... urls){

        InputStream in = null;
        String result = "test";
        int responseCode = -1;
        try {
            URL url = urls[0];
            URLConnection urlConn = url.openConnection();
            if (!(urlConn instanceof HttpURLConnection)) {
                throw new IOException("URL is not an Http URL");
            }
            HttpURLConnection httpConn = (HttpURLConnection) urlConn;
            httpConn.setRequestMethod("GET");
            httpConn.setDoInput(true);

            result = "get here";
            httpConn.connect();
            result = "don't get here";

            responseCode = httpConn.getResponseCode();
            if(responseCode == HttpURLConnection.HTTP_OK){
                in = httpConn.getInputStream();
            }
            httpConn.disconnect();
            result = readIt(in, 10);
            return result;
        }
        catch (Throwable t){
            t.printStackTrace();
        }
        return result;
    }

Any ideas of what is causing there not to be any connection or how to test if I am simply overlooking or not completely understanding this? I can additional code if needed. Thank you
