How can I fix ‘android.os.NetworkOnMainThreadException’?

by

I got an error while running my Android project for RssReader.

Code:

URL url = new URL(urlToRssFeed);
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
XMLReader xmlreader = parser.getXMLReader();
RssHandler theRSSHandler = new RssHandler();
xmlreader.setContentHandler(theRSSHandler);
InputSource is = new InputSource(url.openStream());
xmlreader.parse(is);
return theRSSHandler.getFeed();

And it shows the below error:

android.os.NetworkOnMainThreadException

How can I fix this issue?

    Read this blog post on the NetworkOnMainThreadException for more information. It explains why this occurs on Android 3.0 and above.

    To be on rite track first read about the Network Requests in android then i would recommend to study “Volley”.

    There are many alternative libraries that solve this issue. Many are listed at the bottom of this page. If you got more, we take them 🙂

  • “Due to a bug in previous versions of Android, the system did not flag writing to a TCP socket on the main thread as a strict-mode violation. Android 7.0 fixes this bug. Apps that exhibit this behavior now throw an android.os.NetworkOnMainThreadException.” – So some of us haven’t hit this until recently! developer.android.com/about/versions/nougat/…
