In My Application i am parsing the feed from the net as like below code:

```
private void downloadEpisodes(String Url) {
    //Make Progress Bar Visible While Downloading Feed
    progress_bar.setVisibility(ProgressBar.VISIBLE);
    Log.d("CGRParser", "Downloading Feed");
    //Start an ASync Thread to take care of Downloading Feed
    new DownloadEpisodes().execute(Url);
}

private class DownloadEpisodes extends AsyncTask<String, Integer, ArrayList<LatestNews>> {
    ArrayList<LatestNews> episodes;
    @Override
    protected ArrayList<LatestNews> doInBackground(String... url) {

        //Download and Parse Feed
        XmlFeedParser parser = new XmlFeedParser();
        episodes = new ArrayList<LatestNews>();
        episodes = parser.parse(url[0]);
        return episodes;
    }

    @Override
    protected void onPostExecute(ArrayList<LatestNews> result) {
        //Feed has been Downloaded and Parsed, Display Data to User
        Log.d("CGRParser", "Feed Download Complete");
        displayEpisodes(result);
    }
}

private void displayEpisodes(ArrayList<LatestNews> news_detail) {
    //Create String Arrays to seperate titles and dates
    Log.d("CGRParser", "Displaying News Titles To User");
    ArrayList<String> episode_titles = new ArrayList<String>();
    ArrayList<String> episode_description = new ArrayList<String>();
    ArrayList<String> episode_link = new ArrayList<String>();
    for (LatestNews news : news_detail) {
        Log.d("News", "News Title: " + news.getTitle());
        Log.d("News", "News Description: " + news.getDescription());
        Log.d("News", "News Link: " + news.getLink());
        episode_titles.add(news.getTitle());
        episode_description.add(news.getDescription());
        episode_link.add(news.getLink());
    }

    this.episode_titles = episode_titles;
    this.episode_description = episode_description;
    this.episode_link = episode_link;

    //Create a ListAdapter to Display the Titles in the ListView
    ListAdapter adapter = new ArrayAdapter<String>(this, R.layout.latest_news_row, R.id.title, episode_titles);
    listview_news.setAdapter(adapter);
    //Set Progress Bar Invisible since we are done with it
    progress_bar.setVisibility(ProgressBar.INVISIBLE);

}

```

Now with this code i want to handle the internet availability. If internate is not available then the Message should be dispaly like "Please check the internate connection."

Please help me for this.
