Android get string from HTML/PHP

I can't figure out how exactly to get a simple string from an url. I have tried several versions of this code:

String str = null;
    try {
        // Create a URL for the desired page
        URL url = new URL("mysite.com/thefile.txt");

        // Read all the text returned by the server
        BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));

        while ((str = in.readLine()) != null) {
            // str is one line of text; readLine() strips the newline character(s)
        }
        in.close();
    } catch (MalformedURLException e) {
    } catch (IOException e) {
    }
    Toast.makeText(getApplicationContext(), str, Toast.LENGTH_LONG).show();

With all the proper manifest permissions but can't get to return anything. My txt file just contains

www.google.com

and I can access it from the phone or computer in any browser. Any ideas?

I'm not surprised that this doesn't tell you what's wrong, if I look at your code:

} catch (MalformedURLException e) {
} catch (IOException e) {
}

If an error occurs, you won't notice anything. Just place some kind of error reporting into theses catch branches and look at your logs. By the way, mysite.com/thefile.txt is not an URL, while http://mysite.com/thefile.txt is.

I found the answer here.

Here is the code:

Use the DefaultHttpClient httpclient = new DefaultHttpClient();

HttpGet httppost = new HttpGet("http://www.urlOfThePageYouWantToRead.nl/text.txt");
HttpResponse response = httpclient.execute(httppost);
        HttpEntity ht = response.getEntity();

        BufferedHttpEntity buf = new BufferedHttpEntity(ht);

        InputStream is = buf.getContent();


        BufferedReader r = new BufferedReader(new InputStreamReader(is));

        StringBuilder total = new StringBuilder();
        String line;
        while ((line = r.readLine()) != null) {
            total.append(line + "\n");
        }

        TextView.setText(total);
