Reading XML From HTTP Android

Question

I'm trying to read an xml file from the internet.

This is the code i'm using:

HttpClient client = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.mypage.com/version.xml");
HttpResponse resp = client.execute(httppost);

and I'm getting this ex:

android.os.NetworkOnMainThreadException

I'm trying to do this with an async method following the answers. This is the code I tried:

public class Download extends AsyncTask<String, Void, Document> {

@SuppressWarnings("unused")
private Exception exception;
public Document document;

public Download(String url)
{
    this.execute(url);
}

@Override
protected Document doInBackground(String... url) {
    try {
        HttpUriRequest request = new HttpGet(url.toString());
        HttpClient httpClient = new DefaultHttpClient();
        HttpResponse response = httpClient.execute(request);

        StatusLine statusLine = response.getStatusLine();
        int statusCode = statusLine.getStatusCode();
        if (statusCode == 200) {
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();
            document = builder.parse(response.getEntity().getContent());
            return document;
        } else {
            throw new IOException("Download failed, HTTP response code "
                    + statusCode + " - " + statusLine.getReasonPhrase());
        }            

    } catch (Exception e) {
        exception = e;
        return null;
    }
}

protected void onPostExecute(Document doc)
{
    // TODO: check this.exception 
    // TODO: do something with the feed
    document = doc;
}

}

But the document is null.

Try to include the Web Call logic inside the AsyncTask.

FYI, you can do background process inside the doInBackground() method of AsyncTask.

Or to get rid of problems with orientation change, go with `AsyncTaskLoader` – Michał Klimczak Apr 24 '12 at 07:17
