Answer by Adnan Abdollah Zaki for How do I fix 'android.os.NetworkOnMainThreadException'?

This exception is thrown when an application attempts to perform a networking operation on its main thread. If your task took above five seconds, it takes a force close.

Run your code in AsyncTask:

class RetrieveFeedTask extends AsyncTask<String, Void, Boolean> {

    protected RSSFeed doInBackground(String... urls) {
       // TODO: Connect
    }

    protected void onPostExecute(RSSFeed feed) {
        // TODO: Check this.exception
        // TODO: Do something with the feed
    }
}
