Question

I request a text file from a server. The url does not end in some_file.txt, because the file is created dynamically per the request (not sure if that is even relevant). When I use the code below, I do not read in the text (though I do read in html, if pointed to a url that has html).

            String text = "RESULTS:\n";

            try {  

                String urlString = 
                    "http://appdata.mysite.com/httpauth/" +
                    "hub/DAR_param1_RTQB?" + 
                    "method=query&list=param2"; 

                // Create a URL 
                URL url = new URL(urlString);

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

                String line;
                while ((line = in.readLine()) != null) {
                    text = text + line;
                }                    
            } catch (MalformedURLException e) {
            } catch (IOException e) {
            } catch (Exception e) {
            } finally {
                if ( in != null ) {
                    try {
                        in.close();
                    } catch (IOException e) {
                        Log.e(TAG, "Exception trying to close BufferedReader");
                    }
                }
            } 

            return text;

This returns only “RESULTS:”, but none of the text. What am I missing?

Edit: Here is an example of the file. This is displayed in a browser if the url is pasted into the address bar:

20120120_1734
20120120_1725
20120120_1715
20120120_1705
20120120_1655

You are swallowing all the potential errors that you need to see to troubleshoot this.

In your catch clauses, try adding some code to see the errors.
Something along the lines of:

System.out.println("Error: ", e.getMessage());
