I am trying to create an application that allows user's store RSS feeds and
view articles. I allow the user to enter a URL, but I am having trouble
parsing the XML. When I try to parse the XML from the URL the user entered
I get an UnknownHostException: Host is unresolved: ...
I have added *<uses-permission android:name="android.permission.INTERNET"
/> *to the Android manifest. I have been Google searching for a while but
the only solution I found on StackOverflow was to recreate the AVD, which
didn't work for me.
Any help would be appreciated.
Thanks!
*Code:*
public void createFeed(Context ctx, URL url) {
String method = "createFeed";
try {
targetFlag = TARGET_FEED;
mDb = new RSSDatabaseAdapter(ctx);
currentFeed.url = url;
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
xr.setContentHandler(this);
* xr.parse(new InputSource(url.openStream()));*
} catch (IOException e) {
Log.e(LOG_TAG, e.toString());
e.printStackTrace();
} catch (SAXException e) {
Log.e(LOG_TAG, e.toString());
e.printStackTrace();
} catch (ParserConfigurationException e) {
Log.e(LOG_TAG, e.toString());
e.printStackTrace();
}
}
