Question

I am using the following code to get a page’s source which is a plain text (no html tags) from a webserver on LAN. But I am always getting empty string in return and If I open the same URI in browser I can see the text. Following is my code:

                String url = "http://192.168.1.40/touchscreens/get.qsp?display=1";

                HttpClient client = new DefaultHttpClient();

                HttpGet request = new HttpGet();
                request.setHeader("Content-Type", "text/plain; charset=utf-8");

                request.setURI(new URI(url));
                HttpResponse response = client.execute(request);

                in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

                StringBuffer sb = new StringBuffer("");
                String line = "";
                String NL = System.getProperty("line.separator");

                while ((line = in.readLine()) != null) {
                    sb.append(line + NL);
                }

                String page = sb.toString();

                Toast.makeText(getApplicationContext(), page, Toast.LENGTH_LONG).show();

and one more thing when I enter the same URL in android emulator browser I don’t see anything. Am i missing something?

I recommend you should debug your HTTP requests using fiddler (see http://www.fiddler2.com/fiddler2/). This should debug the internet requests from your browser and your app and show you if your requests are missing the necessary headers.
