A simple RSS reader IV, start browser to open the selected feed

Modify from the former post "A simple RSS reader III, show details once item clicked." When any item clicked, the link of the selected feed will be opened in installed browser, by starting activity with Intent of ACTION_VIEW. The second parameter of Intent() constructor is the target Uri to be opened.

Modify onListItemClick() to:
Uri feedUri = Uri.parse(myRssFeed.getItem(position).getLink());
Intent myIntent = new Intent(Intent.ACTION_VIEW, feedUri);
startActivity(myIntent);

This exercise will fail caused by android.os.NetworkOnMainThreadException for android:minSdkVersion="10" or higher. To fix it, implement the RSS feed reader run in AsyncTask.
