Question

I want to access a parameterized url with Android. All it has to do is “load” the page so that it does what its supposed to do (update database with parameters given).

I was having trouble just loading the url so I watched a video on regular HttpClient activity — just waiting for the response and gathering that information. I figured that it would still be loading the page and therefore also letting that page execute. I can’t even get that to run the page correctly or gather a response.

Here’s the code I used:

String url = "http://www.removed.com?param1="+param1+"&param2="+param2;

        try{
            HttpClient httpclient = new DefaultHttpClient();
            HttpGet httpget = new HttpGet(url);
            HttpResponse response = httpclient.execute(httpget);
            HttpEntity entity = response.getEntity();
            InputStream webs = entity.getContent();
            try{
                BufferedReader reader = new BufferedReader(new InputStreamReader(webs, "iso-8859-1"), 8 );
                test.setText(reader.readLine());
                webs.close();
            }catch(Exception e) {
                Log.e("Error in conversion: ", e.toString());
            }
        }catch(Exception e) {
            Log.e("Error in connection: ", e.toString());
        }

Please let me know what I can do to get this to execute the page and update the database. If I put in the parameters manually into a browser, it works.

You haven’t posted where you’re running this or what the error is, but the first two things that come to mind are:

• Do you have INTERNET permissions set in the manifest?
• If this is Honeycomb, is this running in a separate thread? – As of 3.0 you can’t run HTTP requests in the main display thread.
