Top Android XML and HttpURLConnection Examples

Let's look at some examples.

This is an android RSS Images GridView example with XmlPullParser,AsyncTask ,HttpURLConnection and GridView..We shall download RSS Feeds from a local website and then parse the feed.We then show parsed images and text news in our GridView.

Lets start.

XmlPullParser Overview

  • Is an interface, xmlPull.v1.XmlPullParser.
  • Added in API level 1;
  • Defines how to parse Xml documents.
  • Has two key methods : next() and nextToken();
  • We use XmlPullParserFactory to create its instance.
  • The method next() enables us work with higher level events while nextToken() at a lower level.
  • Invoking getEventType() enable us know the current state of event of the parser.
  • The first event state is _STARTDOCUMENT, calling next() moves us to the next event.
  • A couple of high level events accessible to next() include:
  1. START_TAG => Raised when XML start tag was read.
  2. TEXT => Raised when text content was read. The text itself can be retrieved using the getText()
  3. END_TAG => End tag was read.
  4. END_DOCUMENT => The very last event.
